Scientists exposed the "violating the laws of physics" rocket engine

Representatives of scientific circles of the Dresden Technical University conducted research on the engine EmDrive, which, according to its developers, acts on the principle of "violating the laws of physics."

On the essence of the developers' statement: a conical resonator chamber with a magnetron that generates electromagnetic waves “is capable of transforming these waves into cravings.” It is stated that if you select the “correct” geometry of the truncated cone of the engine, the system will start moving towards its narrow part due to the presence of microwaves within the entire system. In this case, the developers added each time that this contradicts the laws of physics, namely, the law of conservation of momentum, since there is no fuel consumption and there is no generation of a directional beam of waves.

The engine, as stated, when bringing to "technical excellence", can be used in space programs.

Dresden scientists decided to study the EmDrive system in detail and finally concluded that there are no violations of the laws of physics during the operation of the engine for the simple reason that, in fact, there is no work itself.

The effect of thrust arises, but, firstly, it is critically minimal, and secondly, its cause is not the EmDrive itself, but the interaction of the magnetic fields created by the current running along the cables with the Earth’s magnetic field.

Research results published in SpaceDriveProject.

From the material:

Despite the fact that we used as many twisted or coaxial cables as possible, some magnetic fields eventually leak through our cables and connectors. Considering the strength of the magnetic field of the Earth 48 μT with a slope of 70 ° in central Europe, several centimeters of cables and a current of 2A (similar to what is required to power the amplifier), we get the appearance of the Lorentz force, similar to our observed values ​​of "thrust". Therefore, we suspect that the interaction of the power supply for the amplifier with the Earth’s magnetic field masked any real movement that could be below our observed value. In the next installation, we expand our experimental unit so that the configuration of the cavity and the amplifier can be completely shielded with sheets of metal in order to significantly reduce this effect. (...) After our improvement of settings, we will try the dielectric disk configuration, various geometries, as well as higher power levels.

As a result, experiments have led to the fact that the EmDrive design does not represent any breakthrough in physics.

The assumption that this rocket engine in reality does not break anything or does not work was expressed as early as last autumn by US scientist Bryce Cassenty:

EmDrive's work violates Newton's third law, which says that force cannot arise by itself without the interaction of physical bodies. Both action and opposition are the direct result of the work of the law of conservation of momentum. If this law is violated, then all modern physics built on its basis will be wrong. Therefore, many of us believe that all the statements about the work of EmDrive are the product of erroneous measurements.

Research results confirmed this hypothesis. However, this does not reduce the interest of specialists and "fans" to the engine configuration.

Well, if approached from a scientific point of view, then our "Guarantor" at a speech before the federal assembly, apparently received advice on lasers and hypersound from priests and clergy ... And everyone applauded while standing ... It's like dumb people to rub anti-scientific nonsense from the rostrum about lasers and hypersound, absolutely not giving a damn about the fundamental laws of physics? As Mr. Rogozin likes to bother about “new” physical principles (what the term is, it’s not clear), apparently it consists in erasing from the consciousness of citizens the knowledge of the laws of physics. Then for the people they will naturally become "new."

If we talk about the laser, then in principle it cannot become a military weapon. In the best case, their destiny is extremely narrow, specific areas of application such as burning optics for reconnaissance. equipment, sights, single volleys for short distances, etc. If we talk about the use of lasers on the battlefield to “burn” tanks / infantry / missiles / aircraft, then this is just technical nonsense. Here, the physically irresistible diffraction law comes into force, which states that the laser radiation always diverges from the angle = wavelength / beam diameter. There is only one way to deal with beam divergence - by reducing the wavelength. However, it follows from the fundamental laws of physics that the shorter the wavelength, the more difficult it is to implement quantum amplification of radiation, or, in human terms, to build a laser. At distances of the order of meters, it can be ignored. So what is next? If we take specifically a combat infrared laser with a wavelength of 2 μm (THEL combat lasers work at such a length, etc.) and a beam diameter of 1 cm, then we get the angle of divergence 0.2 of the milliradian (this is a very small difference - for example, ordinary laser pointers / rangefinders diverge by 5 milliradians and more). Divergence 0.2 mrad. at a distance of 100 meters it will increase the diameter of the spot from 1 cm to approximately 3 cm (if anyone else remembers school geometry). That is, the impact density will fall in proportion to the area in 7 times only by 100 meters. That is: if we know that a laser with a power of 100 KW burns an inch steel plate at point-blank somewhere in 2-3 seconds, then at a distance of 100 meters it will do this, roughly, 18 seconds. And on a kilometer, the beam density will fall already 300 times. Therefore, it is easy to understand that the distance of hitting a target even in 1 km for an 100-kW laser is an unattainable dream in real conditions. Unless you understand, for example, a canister of gasoline. Or a naked man tied to a tree.

If we talk about hypersound, then shortly before the "enchanting" performance of the "Guarantor", there was an interview with the chief developer of hypersonic weapons in the Russian Federation.

Quote:
Russian developers of hypersonic weapons have to solve the problem of ensuring long-term movement with the hypersonic speed of an object in the atmosphere. This was reported to Izvestia by the adviser to the head of the corporation NPO Mashinostroyeniya on science Herbert Efremov.
According to the expert, for this it is necessary to create ramjet, rocket-turbo-ramjet or a combination of turbo-ramp marching engines. However, according to him, world-famous direct-flow apparatuses, both domestic and American, are exclusively research.
“These technologies have not yet been mastered. Moreover, even in direct-flow engines already tested in different countries, it has not yet been possible to provide stable, reliable combustion in combustion chambers when driving in hypersound. It is still unclear whether these problems will be resolved in the near future, ”said Efremov.
In addition to the development of the marching engine and thermal protection, the creation of a hypersonic apparatus involves the solution of "a mass of other technical problems." “For example, issues of motion control, guidance, the passage of radio waves through plasma. And also ensuring stealth and maneuvering, ”notes Efremov.

Well, what else can be supplemented? Efremov "issued" all the fundamental laws of physics and problems in the field of hypersonic weapons in this interview ... how is it now to cut the state order?

PS It’s good and easy to cut the military budget when the government is ignorant and amateur. Make the main picture beautiful on the video, as a cardboard rocket flies along a predetermined path, and then lights up, as they launch a beautiful hypersonic unit that after a few minutes of flight starts to fall apart when moving at a speed less than three times the declared speed. Nowadays, only beautiful startups are taught to do well! And do not believe fairy tales at all, be realistic and smart people!

It is somewhat strange to read such pseudo-scientific discussions about the failure of Putin's rocket and laser.
The missile, obviously, has no ramjet engine. No one said, however, that this is all easy and simple. But, apparently, the tasks are solved. How? They don’t report about us. If this does not fit in your head, this does not mean that the president is lying.
Regarding the laser ... Academician E.P. Velikhov also spoke about the tests in distant Soviet times of a megawatt-class laser at a range of 1-1.5 km. Of course, this is not much. And there are enough specific problems, such as transparency of the atmosphere, etc. But all this was already then! And now lasers at their peak can deliver up to a gigawatt of power, and indeed science does not stand still.
But if the CIA or Mossad personally reported to you about the lack of entih affairs in Russia, then tell me directly. And you should not start a "cancer for a stone"
Z.Y. In his message, Putin thanked the FSB for secrecy in the development of these weapons. And why did you get what Herbert Efremov said was not part of this cover?

If the rocket does not have a ramjet engine, then there will be no prolonged hypersonic flight. It can only accelerate and fall along a ballistic trajectory, and there can be no talk of any long hypersonic flight. A hypersonic ramjet is a ramjet operating at flight speeds above M = 5. At the moment, all hypersonic engines are experimental: there is not a single sample that has passed flight tests, confirming the practical feasibility of its mass production. Other problems have already been voiced by G. Efremov. Namely, management and thermal protection. And besides, the USA has been trying to solve this problem for almost two decades. And they have a hundred times more opportunities than ours and they, unlike us, pay their engineers and designers. And we have not fed our 25 years. Where does that come from? By magic?

Do not read pseudo-scientific literature. The USSR at one time went all the way to create a combat laser from and to, which the United States is now doing and, in fact, reinventing the wheel. In the USSR, completely different tasks were posed before the laser. Namely: to blind and burn optics of the enemy, target designation, violation and failure of electronic systems and so on. The laser is not capable of anything more in combat conditions, due to weak power, absolute inefficiency, insurmountable laws of physics and elementary and CHEAP methods of protection against it. Remember how many laser projects there were in the USSR, at what time, and what results he achieved. For example, the marine projects FOROS and DIXON, ground TERRA-3, space SKIF-2D, on a movable chassis OMEGA, STYLE, COMPRESSION, DAL, SANGVIN, aircraft A-60. Which were long before the laser Boeings and Firestrikes and also successfully functioned. Only their tasks were completely different.
Regarding the "secrecy" of lasers ... First, learn the fundamental law of diffraction so that our government balabols do not hang noodles on your ears. Lasers have two drawbacks: low power and beam divergence. Whatever the power, but if a beam of radiation with a diameter of several kilometers falls on the target, the benefit of such a laser is zero — unless you can make a rangefinder out of it ... There is only one way to deal with beam divergence — by reducing the wavelength. However, it follows from the fundamental laws of physics that the shorter the wavelength, the more difficult it is to implement quantum amplification of radiation, or, in human terms, to build a laser. And at least you are killed, but it is impossible to overcome it. The beam will still diverge and with it power. The second problem is the balance of energy. As is known, the usual laser operation scheme provides for the “pumping” of the working medium (crystal or gas) with energy up to a certain level, and when a jump occurs, the accumulated energy is discharged by a light beam of a certain wavelength. But where to get that energy that did not go to the goal with the beam? So, for the most part, it will stand out in the firing device in the form of heat. Thus, only 20% will go to the goal (although in reality no more than 10%), but the remaining 80% will remain with us. And therefore, even if we damage the enemy’s equipment, we can easily evaporate our own unit. It is no accident that even in much less powerful earthly installations, flowing water cooling is used not only for mirrors, but also for the working volume of the laser. the most powerful combat laser to date is the ABL chemical COIL laser. Its power is about 1 megawatts. The power of the 76-mm division gun F-22 of the 1936 model of the year is about 150 megawatts. 150 times more! Divide the kinetic energy of the projectile (M * V ^ 2) / 2 by the time it is reached (about 0.01 seconds). We still do not take into account the explosive energy in the projectile itself. There are still as many. Think about this simple fact: a small ancient cannon from the time of the Second World War at a price of scrap metal is hundreds of times more powerful than an ultramodern “battle” laser weighing tens of tons and costing over 5 billions of dollars. A shot from ABL alone costs millions of dollars. And this energy shot is comparable to the burst of a heavy machine gun. The power of a Kalashnikov assault rifle is about 100 kilowatts. A US-Israeli laser with the same 100 kW (THEL) power was tested, they wanted to use it to protect against Grad missile shells. THEL installation in size - 6 delivered next to the bus. The project was closed at 2006 for complete inadequacy, although it still successfully shot down missiles and mines. By heating them in flight for several seconds. (The question is - what about the volley ????) Characteristically, no one even mentioned the possibility of defeating infantry with such a laser. Otherwise, even a child would clearly see its true capabilities, comparing it with an ordinary machine gun.

There will be no development with lasers until they begin to apply, first of all, the mathematical methods described in the Pharaoh’s problem. That is, the beam must be bundled and created with compression and expansion algorithms. A light beam behaves absolutely analogously to a jet of hydro-gas-dynamic flow. The crystal does not allow to form such a stable light flux.

Right! A laser beam in a gas can undergo "self-focusing" when the atmospheric channel heated by the laser becomes a kind of optical fiber. The beam is also able to focus to a point that can become a source of x-ray radiation due to colossal heating in the area of ​​self-focusing. The main thing here is to use this effect so that such a point appears at the right time and in the right place ... But this is already from the category of fiction.

[gridasov]

I’ll fix it a bit. The category of fiction can be a wide area of ​​application, but not in any way, at least the primary methods that can be carried out yesterday. A ray of light is a process of physical sonoluminescence. And if this self-focusing point is formed in the algorithm of its movement in space and along the vector, then we will get a stable energy process. That is, the energy transfer process itself should be converted into a pulse one with a controlled frequency. . In practice, this is done in such a way that, first, it is necessary to use hydro-gas-dynamic sources of a sonoluminescent process, and then instead of crystals, a radiation surface from a circle and in the order of algorithms is used. In general, this is already mechanics.

Respected! Learn the materiel! Understand the difference between the environment of the movement of the object in mid-air and outside the atmosphere. Between the booster block, the booster accelerator, the marching engine and the hypersonic ramjet engine! Hypersound can only be within the atmosphere. Since sound is a physical phenomenon, which is the propagation of mechanical vibrations in the form of elastic waves in a solid, liquid, or gaseous medium. You are very angry with your ignorance.

Under certain conditions, you can run the cart. But in reality, there are insurmountable fundamental laws of physics that do not allow this to be done and there is no way around them. In what "miraculous" way did the law of diffraction and the problem of the remainder of energy be circumvented? And in order to destroy a tank with a "short" distance, as you put it, you need to bring this installation at least a kilometer to the tank, and at the same time burn it for about a minute (depending on the power of the unit), and then if it does not move.

For your information, the USA had such a project as Excalibur. The space X-ray shield project was supervised by the legendary "father" of the American hydrogen bomb, Edward Teller, and was called the Excalibur. Each missile defense station "Excalibur" was about a hundred moving metal rods of x-ray lasers mounted around a nuclear charge. Each rod was combined with a personal target capture and guidance system based on a small telescope. After selecting targets and pointing several rods at each of them, the nuclear charge was detonated, and x-ray laser beams “hit” the missiles. According to calculations, each rod could radiate energy in 5 − 6 kJ over a distance of 100 km. After the first unsuccessful test, there was an encouraging Dauphin test result, during which November 11 1980g. At a depth of 1 306 meters below the surface of a Nevada test site, a nuclear device was detonated. Its capacity did not exceed 20 kilotons. During the test, the new Excalibur design was tested, theoretically calculated by Peter Hagelstein, a young member of Group O. The Dauphin test was related to a combat X-ray laser. Moreover, information about the results of the test is the only, albeit meager source of estimates that are considered experimentally confirmed. Namely, radiation with a wavelength of 1.4 nm lasted ~ 1 ns at an average power of ~ 100 Terawatt. Thus, ~ 100 kJ of directed energy was obtained from the string - as from a machine gun, if you do not take into account the beam divergence on the way to the target. 26 March 1983 year in an underground mine at a test site in Nevada in the framework of the Cabra program was the first, and so far the only, explosion of an X-ray laser with a nuclear pump power of 30 ct. Of this enormous energy, only the miserable 130 kJ hit the tip of Excalibur. An attack with such a sword would not be so far away, because the beam of radiation diverged significantly: every 10 m by a fraction of a millimeter, and after 100 km by almost a dozen meters.
Instead of miraculous weapons, a zilch turned out - in the most ideal case, at least one nuclear missile defense had to be spent on one warhead. And when you consider that many missiles carry several warheads and in addition there are a lot of false targets ... And it is not so easy to disable the target with a laser beam, even an X-ray, because modern warheads can withstand close nuclear explosions. In addition, the moratorium on nuclear tests following the first experiment completely transferred the task of creating nuclear-pumped X-ray lasers to the field of theoretical research.

Where are the social, industrial, economic, scientific achievements of Russia over the past 25 years? Which you can truly be proud of. Where are they? Why are they telling us that the United States is an "enemy", while placing the Reserve, Welfare, Stabilization Funds of the Russian Federation precisely in government bonds, banks in the USA, England, France, Germany and not one in Russia. Just look at the article of the RF BC 96.11 and 96.12 1. The funds of the Reserve Fund, the National Welfare Fund, may be placed in debt instruments in the form of securities of foreign states, foreign state agencies and central banks of the following countries: Austria; Belgium; Great Britain; Germany; Denmark; Canada; Luxembourg; Netherlands; USA... Why is our power rubbing us about patriotism and the achievements of a completely different state called the USSR. Why are they telling us to live badly for their homeland, while the speakers have bills and villas abroad, they tell us about love for the motherland, and the offspring and wives themselves live and study abroad and, moreover, the citizens of another country. Moreover, everyone from "Guarantor" to "defender of traditional values" Ms. Mizulina. Why they scare us with the State Department and the Anglo-Saxons, and they themselves give them all the trump cards and cannot open their mouth against them when it comes to business. When they talk about import substitution, and they themselves use Mercedes, iPhones and drink French cognacs and, moreover, write such laws under which crontons come to our industry with such loans for factories and businesses, with the complete destruction of secondary specialized education and the complete absence of skilled workers. When our Sberbank gives its citizens mortgage loans in 12-16 percent, and in "enemy" Poland or the Czech Republic under 3-4 percent. When the government cannot explain to the people how the state was going to substitute if it doesn’t produce a damn and there are no capacities and nothing has been created for this, no conditions, no production facilities, no specialists. It is possible to continue ad infinitum the "great" achievements of our "wise" government. Recently, Mr. Shuvalov said. "There will be no deoffshorization! Offshore money will hurt the Russian economy! " And the list of backbone companies, in respect of which forced deoffshorization was supposed, includes 199 public and private legal entities. This included the largest enterprises, banks, retail chains, central media and other companies, which together provide more than 60% of national GDP. These are Gazprom, Rosneft, Russian Railways, Norilsk Nickel, Transneft, RIA Novosti, Channel One, Russian Post, AFK Sistema and so on. If we add to this list those offshore companies that are not included in the list of backbone companies, it is easy to notice that almost the entire Russian economy, with the exception of grandmothers selling seeds in the market, is tied to offshore companies. And to be honest it’s a SHAME when WWII Veterans are paid 10.000 rubles on Victory Day, and a regional useless deputy receives 300-400 thousand rubles per month ... is this normal?

PS If we do not learn to think with our own head and do not stop believing in priestly-government tales ... to be beaten to us!

Once again about the law of diffraction. The fundamental law that states: laser radiation always diverges from angle = wavelength / beam diameter and you’ll at least be killed, but it is impossible to overcome it. In principle, electromagnetic waves can be focused, as Alexey Tolstoy wrote, and, in general, all existing projects are not far from the immortal “hyperboloid”. But no matter how precisely the focusing mirrors were made, the beam still, alas, diverges. And the degree of this discrepancy is directly proportional to the radiation wavelength divided by the beam diameter. It turns out that the shorter the wave and the wider the beam, the smaller the discrepancy. And in order for the beam to be effective, it must be thin, otherwise all the power is scattered over too large an area. Thus, the main military effect of the laser beam is purely thermal, light quanta should simply be absorbed by the affected object and heat it to such a state that it becomes unusable. In order to have an effect on the target (the metal hull of a ship or aircraft), a certain number of joules must reach it. How much is difficult to say. Depends on the degree of security of the object. And yet, apparently, it is at least several tens or even hundreds of megajoules - for such vulnerable objects as a rocket with a full fuel tank, and at least thousands megajoules - for nuclear warheads that successfully overcome dense layers of the atmosphere without losing operability . For a continuous laser, even without taking into account the beam divergence, we are already talking about powers of thousands of megawatts. But then it turns out that the power of the energy source should be millions of kilowatts!
And you can safely forget about missiles flying in the atmosphere at 20 speeds (as our "Guarantor" blurted out) ... since at the moment, humanity simply does not have such technologies.

And space shuttles at what speed move in the atmosphere during landing? We manage their flight!

[Saburov]

Quote: faradien

And space shuttles at what speed move in the atmosphere during landing? We manage their flight!

In general, shuttles enter the atmosphere and immediately begin to brake this time. Secondly, shuttles have ceramic and PIR thermal insulation. Thirdly, shuttles do not have a prolonged hypersonic flight in the atmosphere. For that short period of time, at high speeds, the heated air for some time disconnects from the control center.

If in detail. Landing consists of several stages. First, a braking impulse is issued to leave the orbit — approximately half a turn to the landing site, while the shuttle flies aft forward in an inverted position. The duration of the orbital maneuvering engines is about 3 minutes; characteristic speed taken from the orbital speed of the shuttle - 322 km / h; such inhibition is sufficient for the perigee of the orbit to be within the atmosphere. Then the shuttle performs a pitch turn, taking the necessary orientation for entering the atmosphere. The ship enters the atmosphere with a large angle of attack (of the order of 40 °). Keeping this pitch angle, the ship performs several S-shaped maneuvers with a roll of up to 70 °, effectively damping the speed in the upper atmosphere (this also minimizes the wing lift, which is undesirable at this stage). The temperature of individual sections of the thermal protection of the ship at this stage exceeds 1500 °. The maximum overload experienced by astronauts during atmospheric braking is around 1,5 g.
After the extinction of the main part of the orbital speed, the ship continues to decline as a heavy glider with a low aerodynamic quality, gradually reducing the pitch. A landing maneuver is being carried out. The vertical speed of the ship at the descent stage is very high - of the order of 50 m / s. The angle of the landing glide path is also large - of the order of 17-19 °. At an altitude of the order of 500 m and a speed of about 430 km / h, the ship begins to level and the landing gear is released. The strip touches at a speed of the order of 350 km / h, after which a brake parachute with a diameter of 12 m is released; after braking to a speed of 110 km / h, the parachute is reset. The crew leaves the ship in 30-40 minutes after stopping.

While you can calm down at the thought that the laws of physics triumph!
When will we, let our descendants, see that the time has come for the supremacy of the laws of reason! Will the time come, or is it a pipe fantasy?

Mutually, Victor!

It is not so easy to answer your question. "The magnitude of the mind on the planet is constant, but the population is growing ..." (c)

[rocket757]

Well, the universe identity is expanding, it seems non-English scientists have proved this.
To look for a receding mind in it, these are deeds, even the fulfillment of a yes-and-red future.
I wish there was enough Schaub mind on our planet, Schaub our descendants lived up to that time and accomplishments!

It would be nice for us to look at this with at least one peep.

[rocket757]

A couple of options are available!
Children at our reincarnation in the future - at mysticism, however, and spiritual!
You can look at the masterpieces of Hollywood .... the fantasy is continuous, but sometimes it is very beautiful and spectacular!
I don’t propose about cryogenics, as long as it is about scientific quackery.

[bouncyhunter]

There is another option - to urgently become the Duncans MacLeods.

[rocket757]

Oh, I forgot .... however, it’s innate, it turned out later that it’s finally an alien!
Does your aunt have an alien with an elixir of immortality or at least rejuvenation?

[bouncyhunter]

It was. But this bastard replaced all the elixirs with a chat at the store's forgotten stores. I thrust him into a plate of Evonoy out of anger and sent a delicious pendell to my homeland (Alpha Centauri).

pasha It’s just not easy ... There’s another law, the law of equilibrium ... well, if good happened at one end of the earth in spite at the other end to neutralize evil ... I’m booming, do we bring a lot of good, America is already green from evil ... maybe it would be necessary to use a couple of nuclear weapons to use it, and then they will bake cakes for the poor ...

The namesake, hello! We need to do more good deeds - then the mattresses will be bent from their own anger and poison.

They triumph if liquids having easily evaporated fractions do not affect the physical body. Here recently in Syktyvkar one alcoholic dropped out from the 5th floor changing the gravitational field of the earth and the speed of a freely falling body. Having recorded contact with the ground, this “explorer” in one socks ran away “to the library”, thereby destroying the established physical quantities and amazed the police and the ambulance. And you say))) When it is possible to create a drunken atom, then all physics will give us an understanding that we do not understand anything in physics.

[rocket757]

For some reason I’m not surprised at such a fact of unlawful antiphysical effects of liquids, which are often called simply OH! In the common people AWL!
It has a wide range of effects, depending on the moral and physical condition of the target — from flights / landings, contrary to all physical and other laws, to manifestations of emotionally awkward fluctuations, in the common people designated as - Shaw in a sober mind, then in a drunken language! !! - and a lot of all sorts of different things!

, Paul.
The exposure of this “engine” passed two months ago. To make this bucket work, you need to add Dneproges or NPPs to it. Everything in our world rests on energy and its efficiency. Although the idea itself, in general, requires attention.
Came across like an interesting article. However, read it yourself:

By the way, our developers have begun to create a mini-atomic reactor on a heavy liquid-metal coolant, and this is a breakthrough.

If we assume that the physical vacuum is some kind of structure, and not an abstract "void", then such an engine is quite real. The effect occurs due to asymmetry - a bucket (truncated cone). Electromagnetic waves in a bucket create an electromagnetic field in which the tension at the top and bottom is different. And if we assume that the electromagnetic field is able to act on a physical vacuum, then a force gradient should arise from the top to the base. And all these critics must be driven away with rags.

[gridasov]

Why guess? A vacuum is simply a structure of finely dispersed, if one can say so composite. Therefore, the energy density of interactions is higher than in the environment of gases and air. Therefore, the vector of radial pressure relative to atmospheric outward. It is not clear why this causes a problem of understanding. What is a vacuum.

Let's wait, what China will say, they like it are already testing in space. And one wants to believe that humanity will at least somehow break out of this cosmic stagnation. But while it’s more profitable to fight ....

[Dormidont]

And that’s true, why fight on Earth when there is so much space in space for this

[voyaka uh]

Right Did not see your post. Wrote a post about this below.

[vadimtt]

Strange conclusion in the article, significantly different from the original
In general, the researchers began to make the following installation in order to remove all the alleged side effects and also continue to experiment with the geometry of the engine, i.e. research work is underway and there are no "iron" denials.

[mac789]

The unit itself is garbage ... But if the camera is strengthened and the fuel - oxidative mixture is pumped into it, then the burning rate of the mixture will seriously increase. Which will have a positive effect on traction.

[Svetlana]

Quote: mac789

But if the camera

If you open the Emdrive conical chamber for the exit of microwave radiation from the wide end, then it will emit spiral microwaves - helicons. Helicons interact with the Earth’s magnetic field in near-Earth rarefied space plasma, take away momentum and enhance the thrust of the engine, compared with the thrust generated by emitted microwave photons without taking into account their interaction with the Earth’s magnetic field

In fact, a completely understandable analysis when testing this "phenomenon" could be done by its developers, but PR is more expensive. They love to do self-promotion. The economic "miracle" Mask also hastened to publicize. But it turns out that his "violation of the laws of the economy", to put it mildly, turned out to be a bluff - without the state. recharge his "perpetual motion machine" also does not spin for a long time

[Blackmokona]

Not the developers, but the developer could not. As we see from the article, plus earlier information from this university. They’ve been picking their hands for about five years, and still can’t say ironically that there is no abnormal traction and continue to work.

[Valerevich]

And do not care that the pan with wires and bolts, the main thing is to properly promote.

The Chinese have done easier. They do not puzzle how this engine works or does not work: they bought a license, made it on a large scale and are going to launch it into space far, far.
And check in real conditions: it will fly - it will not fly

[Vadim237]

This engine will have a thrust like an ion.

[Servisinzhener]

Since the beginning of the 20th century, such a phenomenon as the pressure of electromagnetic radiation is already known. So there is nothing violating the laws of physics here. This conditional microwave emits photons, therefore, a pulse should appear directed in the direction opposite to the movement of the photons. The main question that scientists did not answer, unlike reporters with a headless title. How large is the impulse obtained in this way, in comparison with other effects that occur during installation on the ground.

[tivivlat]

in other words, the 15-watt LED flashlight has much more thrust!

[Mayor]

Friday article .. Complete nonsense, the author seems to be a medic or philologist. Or maybe Gridasov himself. Author ay do not wrap magnetic waves in a candy wrapper.

[gridasov]

And what are you smart? Magnetic force processes are calculated by a special method — like a system of symmetries. Therefore, physicists cannot correctly describe the magnetic fluxes of a simple dipole. Not to mention other interactions

[gridasov]

Saburov,
The path to solving this particular problem lies primarily in the methods of analysis of such processes. Therefore, it is impossible to construct a theoretical model of such complex processes by computational methods. We will not be able to combine quantitative expressions with geometric, and even more so with physical concepts. And only by changing and expanding the mathematical methods of analysis we can solve the problems of energy generation and the formation of stability of laser beams and hyper speeds and all that corresponds to the spirit and level of our dynamic time.
Now we just hit the wall. Therefore, in order to make a breakthrough in knowledge, one must be prepared to accept something that not everyone can understand right away. But this is simply a function of a constant value of the number, which will allow constructing a mathematically inextricable local space with all the variations of its transformations. And the method and device of direct transformation of the beginning of the number in e-mail. magnetic impulse will allow you to create AI adapted to our goals and objectives. This is not fiction anymore.
