Lockheed Martin received a contract to build a "quiet" supersonic aircraft

The National Space Administration (NASA) awarded Lockheed Martin a contract to build a prototype passenger supersonic aircraft, reports TASS.

The test flight of the liner is scheduled for the end of 2021. The total amount of the transaction was $ 247,5 million. The development will be carried out by a division of the company called Skunk Works.

The project will be based on the noiseless sound barrier technology developed by NASA. “Most modern fighter planes can accelerate to supersonic speeds (over 1191,6 km / h), but after the flight there is a deafening boom caused by the so-called sonic boom. This is the reason for the current ban on the implementation of supersonic flights by civilian aircraft aviation", Explained in the company.

The construction of the new aircraft will be held in California. As planned by the customer, it will be an aircraft “capable of climbing 16,7 thousand meters and reaching speeds of 1512 km / h.”

It is noted that the sound impact is inevitable, but the designers intend to reduce this noise by more than half (75 decibels).

According to company spokesman Dave Richardson, a prototype is being created to collect data, "which will determine decisions made regarding the future of commercial supersonic flights."

Currently, there are only two supersonic passenger aircraft, mass-produced. These are the Soviet Tu-144 (exploited from 1975 to 1978 year), and the English-French "Concord" (made flights across the Atlantic from 1976 to 2003 year).

There will be no real plane ... ask yourself how much will a ticket for such a liner cost? And where will you find so many idiots for at least one flight of such a liner?
Passenger supersonic can still exist only in Jet class aircraft with 20-30 seats.

[UAZ 452]

I add - the market for such business jets will be in the tens of cars around the world. Because not every billionaire will pull operating costs on such an ashes.

[Vadim237]

The Emirates will definitely buy 100 of these airplanes - travel the world with super sound and comfort, the ticket price will be around 4000 bucks - in business class. Many businessmen will pull.

And what's so strange? 1,6 billion rubles - about $ 30 million, which is less than the cost of a serial modern aircraft. And $ 247 million for the prototype ... Well, firstly they will develop not from scratch, not the first supersonic device in the world, and secondly - not only in the course of execution, the contract value can quietly paint on the right as well, the American defense industry not less famous.

[Kot_Kuzya]

A silent supersonic aircraft is as nonsense as a dynamo-jet cannon without sound and flame. At first they would at least make subsonic noiseless. I remember that Tukhachevsky demanded to create a DRP without flame and smoke from behind, so that they could be installed in the towers of tanks and ships. Well, at least Tukhach can be understood, he last studied in 1914 and then there were no such things. And these Americans? Cool all the same, the Pentagon is sawing a budget.

The Pentagon, as follows from the article, has nothing to do with it. You can cut any budget, not just the military.

[iliitchitch]

"..Nasa's noise-free technology to overcome the sound barrier ..". Damn, I may be a savage, but will someone explain to me what this thing is?

[Kot_Kuzya]

This is the same thing as stealth planes “invisible” on locators and tanks that are “invisible” with thermal imagers.

[Ardein]

Well, what? ... a very small airplane is being made ...
But seriously, the strength of an acoustic shock depends on the size of the object and the distance (height).
At least we were taught that. And SPS-2, if it is developed, it will be a very small business jet.
PS And in general, if it gives out 75dB on the ground, being at an altitude of 16000m ... a lot, however)))

[Horon]

I also thought that they would drive the plane higher and there they would switch to supersonic, but of course they let fog through with:

The project will be based on the noiseless technology developed by NASA.

Another unmatched seafarers! A rocket launching vertically and breaking the sound barrier at high altitude is also “silent”.

[Gray brother]

Quote: iliitch

".. NASA-developed noiseless sound barrier technology.

This is all from the wretchedness of American education.

There is a misunderstanding connected with the “clap” caused by an incorrect understanding of the term “sound barrier”. This “clap” is properly called a “sonic boom.” An aircraft moving at supersonic speed creates shock waves in the surrounding air, air pressure surges. Simplified, these waves can be imagined as a cone accompanying the flight of an aircraft, with the top tied to the forward fuselage, and forming up against the movement of the aircraft and spreading quite far, for example, to the surface of the earth.
When the boundary of this imaginary cone, denoting the front of the main sound wave, reaches the human ear, a sharp pressure jump is perceived by the ear as a pop. The sonic boom, as tied, accompanies the entire flight of the aircraft, provided that the aircraft moves fairly quickly, albeit at a constant speed. Cotton seems to be the passage of the main wave of a sound strike over a fixed point on the surface of the earth, where, for example, the listener is located.
In other words, if a supersonic aircraft with constant, but supersonic speed began to fly over the listener back and forth, the cotton would be heard every time, some time after flying over the listener at a sufficiently close distance.

I don’t know for sure, Lockheed has been tormenting this topic for a long time. They try to damp vibrations due to aerodynamics and tail (smooth forms, counterpropagating wave). There is another topic, turbulence induced by plasma regions ...

[Horon]

Plasma can reduce air resistance, but for an airplane this means a drop. Plasma does not fit! But with increasing height, not only the distance to the observer will increase, but also the vacuum. A less dense medium will reduce the sound effect of the flight and the sound will simultaneously "get stuck" falling into more dense layers. Everything else from the evil one is fog for advertising purposes!

[gridasov]

There is not even a theoretical justification for what is a sound barrier. Accordingly, there is no and cannot be a solution to level this effect.

[Herculesic]

Well, yes, and if he goes into space at all, he will become a spaceship! Theory from Pinocchio from the usa - the higher the plane, the smaller it is from below ! As if without them, no one had guessed to accelerate the aircraft to supersonic speed at the maximum height that this aircraft could climb!

NASA is quite serious, as evidenced by the $ 20 million tranche that the agency gave Lockheed Martin to develop the X-plane design.

Judging by the approximate number of passenger seats - that in the video, in the picture - one or two, then just the same for them.

[gridasov]

Aerodynamic schemes do not resolve these issues. This is the level of magnetic force interactions between the medium and the object.

[NN52]

Lockheed does not try to exclude this effect in principle, but only to reduce it .. As they write ...
Therefore, at this stage, knowledge of the laws of aerodynamics, there are no options, you need to experiment with circuits ... Maybe for now ...
You can hear on earth ...
In the cabin anyway ..
And so, I’ll tell you from my own experience, when supersonic transitions in the cockpit, THERE IS NOTHING ABOUT ANYTHING, only the arrow jerked a little, and that’s all ... We dispersed until 1762 ...

[gridasov]

And the question is not only in the acoustic effect. The question is that the sound threshold is a change in the direction of the perturbation cone. That is, at a subsonic speed of flight, the cone is in the opposite direction from the direction of flight, and with supersonic sound this cone not only changes direction, but also the angle. And what is a cone worth explaining? Therefore, when tending to hypersound, an object can collapse if the momentum of changing the direction of the disturbance is too high. After a sound threshold, the object itself becomes a source of disturbance.

[NN52]

gridasov

I don’t understand something ... you decided to check me?
There is no "cone" on the subsonic, but there are spherical waves of indignation (to be honest, I had to refresh my knowledge of aerodynamics >>)
And how is it on supersonic, cone, which is not on the sound, also changes direction ??? Do not understand? Where is changing direction ???
Maybe in supersonic, in simple aviation language, disturbances already occur on a conical surface? And is this called a cone of indignation or a Mach wave?

And yet, I’m more practicing all the same .... I’m not strong in near-scientific topics ...
As Pete Mitchell said, we need to push this more with ores .... and take RUS smoothly and proportionately onto ourselves ...

[gridasov]

No. Nothing personal. Just writing and reasoning. Resting

[NN52]

Well then, I will ply you, do not be surprised ...

[gridasov]

The question is not the high cost, but the fact that new technologies of motion at hypersonic speeds in the space of an elastic atmosphere should be based on theories that open up all levels of prospects for the future, and not be a single and spontaneous solution.

Putin has already given the task of the Tupolev Design Bureau to develop a supersonic passenger aircraft based on the Tu-160. As for the "shock wave" when overcoming the speed of sound, special air routes were allocated for flights. Overcoming the sound barrier, passed over sparsely populated regions or over the sea.

In the static position, radioactive material, according to the signs of emission of potential energy, is such and there is no replacement for it. But at a high speed of relative motion of any solid material in an elastic ionizing medium, or vice versa, the movement of the medium relative to the material, there are signs of the manifestation of internal potential energy comparable with radioactive radiation. Moreover, natural radioactive material has radial radiation, and under conditions of artificial extraction of potential energy, such radiation is linear, which is more advantageous. Therefore, the principles and concept of energy generation during the initiation of ionization processes in any material in the environment of high potential interaction with the flow of ionizing gases or liquids is very attractive for creating closed energy generation circuits in installations for both space conditions and underwater conditions, as well as for creating motion processes in ion engines.
