American developers are betting on the "broadband stealth" of the new "stealth" bomber B-21

111

In recent years, there has been an increase in criticism of "stealth" technology, which the Pentagon made a bet on when creating new aircraft, such as the F-35 fighter and the B-21 bomber. Contrary to this position, they decided to go to the Institute of Aerospace Research. Mitchell, declaring the possibility of "invisibles" to escape persecution by anti-aircraft weapons, which are in service with the RF Armed Forces.


The findings of this American research organization, working for the needs of the Pentagon, were published on the pages of the NI publication by the former weapons designer for the US Air Force, Chris Osborne.

The report points out that an air defense system, such as the Russian S-300 and S-400, is a complex set of components. They have several types of radar. One, massive, radar is responsible for reconnaissance of airspace and target designation, another radar, smaller in size, is actually responsible for pointing the missile when intercepting an aircraft.

Finding and identifying the target is far from everything. It must be intercepted and destroyed.

- notes retired Lieutenant General David Deptula of the Mitchell Institute [although his statement is not entirely clear, since the target acquisition radar is also responsible for tracking it, transmitting data to the missile defense system until the combat mission is completed].

As Osborne explains, American developers intend to cope with the S-300 and S-400 by using "updated" stealth technologies on new aircraft, relying on the development of already embodied ideas in the form of the F-117 and F-35.

They believe that the transition aviation to a new level will be carried out not only due to the evolution of the characteristics of "invisibility" (reducing the unmasking properties of the structure, reducing IR radiation, the use of materials that are hardly noticeable to the radar). It is supposed to actively use the increase in the capabilities of aircraft in the field of electronic warfare, deliver a preventive strike on air defenses and carry out a "flock" attack, during which "invisibility" will be covered by more visible vehicles, diverting enemy air defenses to fight them. The developers call this whole set of measures “multi-band or broadband stealth”.

As the most promising design at the Mitchell Institute, they call an apparatus that does not have a tail, like the promising B-21 bomber. This technology reduces the reflection of the signal from the side, making it difficult for the enemy radar. At the same time, the developers point out that it will not work to deprive the fighter of the tail and wing, since then it will lose the speed and maneuverability necessary for air combat.

        For bomber engines, they can make a distributed exhaust, that is, several technological holes across the fuselage. As for electricity, back in the days of the USSR, a reactor was tested on board the Tu-95. Plastic engines are not needed when there are composite engine cowlings.

          Will not work. There will be big losses in jet thrust. A powerful jet stream is needed for the aircraft to gain and maintain the required speed. For the principle of jet propulsion is used.
          It would seem that then the jet stream can be abandoned in favor of propellers. But the propellers themselves will "radiate" in the radio range - don't worry, Mom.

            Not an aviation specialist from the word "completely", but, it seems to me, 500 household fans are unlikely to be able to replace two An-24 propellers. lol
            Probably the same story with jet planes?

                With your permission, using the fact that I found a person who understands this, I will allow myself another question. But this thing -
                Did the Americans not have suitable engines? Therefore, they stumbled as many as eight pieces? "Ruslan" completely manages with four. And, as I understand it, the effectiveness of two, but huge ones, would be higher?

                As far as I remember, there is a basic and universal rule - the more links in a closed system, the more likely the system will fail due to a malfunction of one of the links (or something like that). In Russian, it is easier and more reliable to foresee possible malfunctions and carry out preventive maintenance in two or four engines than in eight.
                And again, as mentioned above Lt. Air Force stock about the "distributed exhaust" ...
                I don’t understand anything about jet engines, so I apologize in advance for possibly stupid questions. hi

            Well, it depends on what they will use if there is a high degree of bypass, then there is more thrust not from the reactive circuit, but from the fan circuit. Look at the GE90-115B from the Boeing 777. The B-21s are planning to go subsonic at 900-950 kilometers per hour. There will be losses, but not critical, the thrust may well be the main one from the amount of air passed through the fan circuit as on the GE90-115B, and not from the jet stream.

              And where will you (or rather, they) hide this giant fan? So that it does not glow on the radar like a sea beacon in the night. Here, the compressor blades of a conventional WFD shine like a spotlight. Because of what you have to trick all sorts of S-shaped input paths. Despite the fact that the dimensions, in comparison with this monster, are trifling.

                And you don’t need such a big one, it has a thrust of 52 tons, the B21 is planned to be smaller in size than the B-2, I described the principle. B-2 is a rather "fat" aircraft, there is room.

          Air Force reserve lieutenant, are you definitely from the Air Force? You won’t remove the thermal radiation from the exhaust, but the thrust will drop significantly. In addition, it is enough to install an AFAR on a large high-altitude UAV, and from a height it will perfectly notice this bomber at the maximum detection range!

            And yet, thermal radiation comes only from the first circuit (reactive), from the second fan the temperature is not so high (after all, in fact, the role of the propeller is played by the fan blades, and as you know, the exhaust from the propeller is not thermal). It is necessary to shield only the first circuit from temperature, but the first circuit does not give high thrust, so you won’t lose much.

              Both circuits must be shielded. Because the blades of the fan second circuit have a huge RCS.

                Since in bombers the engines are inside the fuselage, and not on pylons under the wings, I see no problems, there are radar blockers and S air ducts. They can be used both front and back. But behind the hot exhaust is mainly from the primary circuit.

              Air Force reserve lieutenant, in fact, the blades, dispersing the burnt fuel themselves, also heat up! They don’t drive cold air, but hot fuel vapors. And, the heating will be high, which means that forced ventilation such as holes in the case will give a significant loss of traction.

                Not if there is a design something like the NK-93. True, this is not quite a turbofan engine, but propfan.

                    This is the first circuit, it gives meager traction compared to the second. It can be specially cooled (exhaust of the primary circuit). But the second circuit can be distributed over several exhausts.

                      Roughly speaking, thrust-flight in the air is carried out by pushing air, dividing the exhaust, you still have to apply it to the mass being moved, the turbine still has a direct-flow application of energy, unlike a piston engine, and as long as everything runs on kerosene and not cocacola with mentos, it will be warm , it can be smeared like on a flat nozzle, it can be transferred to the body like on b2, but it does not go anywhere

                        In general, it is correct (depending on the degree of bypass of the engine), but I don’t understand what confuses you? The jet stream leaves the chamber, a jet of air is ejected next to it (directly from the air intake or through a compressor), they mix before leaving the nozzle, the average temperature of the jet drops.

                        this is already done by the turbine, before the nozzle exits, the admixture pressure should exclude countermovement, it is easier to install a less powerful but colder engine, so you can get back to the pistons or electric traction)

      In the last century there was an article about the EW B-1 station. The point is this. The receiving station determines the direction and characteristics of the radiation, and the transmitting station sends back the same wave in antiphase. If I'm not mistaken, the author called it an annihilation signal (how!). Now the Americans have heaped up and not like that? This article does not include this topic. What will those born to fly say?

      Such technologies have been around for a long time. This is a meter range radar. Moreover, due to the minimization of the effect of "shiny dots" in stealth aircraft, meter-long radars detect them a little further than conventional aircraft. Now these radars are being improved to improve accuracy, in order to turn them into not only detection systems, but also guidance. That is why some American publications are trying to separate the tasks of detecting and hitting a target. It is necessary to somehow justify the huge costs for something that is easily detected by the Russian radar. Well, what they can’t hit, so far, no one needs it. So, in fact, with invisibility - the best invisibility is the one that does not exist.

        So far, they haven’t come up with anything invisible ... also stealth, it plays from one angle, and when the whole detection system is working, it’s not realistic to hide.
        In combination with interceptors, it all works effectively.
        And it's time for homing missiles.

          I can only recall the 2 downed F-117s in Yugoslavia, which are much "inconspicuous" than the F-35 and 22. Moreover, they were shot down with old air defense systems.

          Not certainly in that way. The broadband signals used on the Nebo and Niobium radars make it possible to achieve an accuracy of only a few meters in range, which is more than enough for any missile. And in order to reduce errors in azimuth and elevation, distributed systems are created from several radars of this type. I don’t know how it is now, but 10 years ago, such studies were conducted quite actively.

            Well, this will be equivalent to increasing the antenna. Moreover, in order to achieve acceptable accuracy, such radars, probably at least a dozen, will be required. And how many of them will be required to cover at least the European part of Russia - it's scary to think. Huge "burdocks" will spin on each hill.

              I wrote a few. Ideally, double overlap from 2 perpendicular directions relative to the target is sufficient. This is even now a standard situation for central Russia where 70% of the territory has a 3-fold overlap.

            Normal - you can, but there is little sense, since there is no surveillance radar - the fighter will be seen only from the front or close. But stealth is pointless: only passive means of detection work in flight (there is still a sub-noise mode of operation of the radar, but I don’t know what and how it can be seen).
            The Americans were going to make a strategic bomber that would itself break through air defense (both ground and air), but they made the B-21.

              Exactly. If the MiG-31 detects "stealth" kilometers at 20-30 kilometers, then the "stealth" by "passive means" will notice the radiation of the powerful Mig radar at 200-300 kilometers. Of course, you still have to somehow determine the distance. When the distance is reduced enough, you can launch a rocket directly into the radar radiation. The range of new versions of "Amraam" is up to 160 km.

    Politicians do not know physics, and businessmen from the defense industry take advantage of this. There are no objects invisible to the radar. There are more or less noticeable ones. To detect an object, you must either increase the radiation level (power) or increase the sensitivity of the receiver. Well, or both together. And how nice it is to "cut" billions of dollars of budgets, knowing the result for sure ... How they then faked the results of the "invisibility" of the F 117 !!! When that kind of money is at stake, they buy any acceptance commissions.

    And secondly, this is a real problem for the defending side and requires an integrated approach to the solution, which costs more than 3 kopecks.

    They believe that the transition of aviation to a new level will be carried out not only due to the evolution of the characteristics of "invisibility" (reducing the unmasking properties of the structure, reducing infrared radiation, the use of materials that are hardly noticeable to the radar). It is supposed to actively use the increase in the capabilities of aircraft in the field of electronic warfare, deliver a preventive strike on air defenses and carry out a "flock" attack, during which "invisibility" will be covered by more visible vehicles, diverting enemy air defenses to fight them. The developers call this whole set of measures “multi-band or broadband stealth”.
    So he blurted out all the secrets! soldier

    Another scam for USA taxpayers wassat "no visibility" - NO !!! A vivid example is the detection of the downing of a B-117 in Yugoslavia by a "poor" USSR air defense station of the mid-50s model! It's all about "how and from what angle to look" - frequencies, frequencies, frequencies! + modern "volumetric" air defense systems - yes. Although the absolute invisible, Everything is "at a glance"! Guys, develop "hypersound", "combat lasers" - This is the topic! but also, not the Ultimate weapon!

    F-117 rolled out of the old Soviet S-125. American "invisibles" have not even met with the S-300, I'm already silent about the S-400. The F-177 was still a clumsy trough because of its shape. Do they seriously hope that such a trough will not overtake the MiG-31?

    Guys, you are just like those generals preparing for the last war! A swarm of drones (yes, exchanging information with each other and all that stuff) will put out your air defense, hello! just open the air defense system and ...
    Well, then all these f-… and b-… will fly
    Well, if you need more.

    American developers are betting on the "broadband stealth" of the new "stealth" bomber B-21

    On TV they showed how they detect and intercept the F-35 by our fighter.

      it was a long time ago, the theme of the Falklands. Argentina greatly blew the British fleet. their planes were bad, but the missiles easily detected the target. Our conclusions were made - we developed a coating that dampened the reflected signal. The desired effect was achieved by simply applying layers until a given k-reflection was obtained. The maximum value is 1,0. I managed to get 0.1, maybe less, I was developing a rig for measuring acid, not coatings. Pulnul frequency 10 GHz - on the display the result and so the accumulation of up to 5 results. instead of a team of guys dragging trolleys with bridges along the side (stock) it is a piece of iron with a micrometric mechanism and with a needle, it is necessary to determine the antinode or knot, etc.). in general, they were taken to the Central Research Institute of Krylov and everything was shown on the layouts, then I quit and left for NZ. The guys from the Central Research Institute were shocked. They measured all the pieces of enoplast with steel wire, calibration sheets of plexiglass and everything that was. The measurement accuracy was up to 0,01. and coincided with their pre-signed values. Sorry for the tour. It seemed that she was a panzeya - smear and hide. only it was possible to hide only at that frequency the object at which the radar operates. they irradiate you with 10 GHz and zero back .. nobody. It was upsetting that it was worth changing the frequency and in the wider frequency band, the object protruded at a glance. For example, a radar with a frequency that changes in some way will detect an object without difficulty. Or, as a generator, a spark diode emitter with a wide emission band. My knowledge is outdated, this is 1983-86, but then it was clear that it would not work to hide at all. so these stealths - you can see them if something has been developed by this time. I have not yet met a material that would absorb a signal in the entire band.
