Advanced reconnaissance aircraft SR-72

When the American reconnaissance aircraft SR-1998 Blackbird (Blackbird) made its last flight in 71, the United States Air Force lost one of its most high-tech aircraft ever built. In addition, the SR-71 was simply one of the most beautiful aircraft in the world. However, SR-71 will not be left without a successor. At the end of 2013, the information appeared that a new plane, which received the designation SR-72, would replace the “Blackbird”, which was developed by the division of the aircraft manufacturing corporation Lockheed Martin. It is reported that the main difference between the aircraft will be a completely new engine, which will combine the turbine and direct-flow jet propulsion. Thanks to this engine, the aircraft will be able to fly at a speed of about at 6 Mach, which is immediately 2 times the maximum speed of its predecessor.

One of the symbols of the cold war era Lockheed Martin SR-71 Blackbird can get a receiver in the next decade. It is reported that the new SR-72, capable of flying at twice the speed, will be able to fly without a pilot. After the US Air Force abandoned the "Blackbird", they showed a serious shortage of such machines. The SR-72 aircraft, which is being worked on by the design engineers of the Lockheed Skunk Works unit, must return to the Air Force reconnaissance flight at supersonic speeds. If the project is completed as planned, the aircraft will be able to fly at a speed of 6 times the speed of sound.

The spy plane SR-71 made its first flight back in 1964, the last time the car took to the air in 1998. All this time, the Blackbird remained the main reconnaissance aircraft of the US Air Force. The machine could be in the air for a long time at an altitude of about 24 kilometers, flying at supersonic speeds. When the SR-71 was retired, for some time the role of high-altitude observers was transferred to the orbital group.

However, the use of reconnaissance satellites is not the most ideal of all possible solutions. Modern reconnaissance satellites are able to obtain very detailed photographs of various ground-based objects in high quality, but they require considerable time in order to retarget the device, transferring it to another orbit. For example, the movement of mobile missile systems more efficiently and reliably track with a hypersonic aircraft. Unlike satellites, the new SR-72 hypersonic reconnaissance aircraft, according to the developers, will be able to appear above the target so quickly that the likely adversary simply cannot respond to its appearance and hide from its equipment.

It is worth noting that even in 1990, the Blackbird set a record for flight speed. It flew from Los Angeles to Washington, in just over an hour, flying at Mach 3,3 speed. In order to fly at even greater speeds, the new SR-72 is planned to be equipped with a scramjet - a hypersonic ramjet engine that uses a special mixture of supercompressed air and fuel. Combustion of this mixture will allow the aircraft to fly at hypersonic speed or close to it.

But first we will have to overcome a number of technical difficulties associated with the project. Since super-compressed air is used in the scramjet, it is not suitable for flying at low speeds. In order to solve this problem, Lockheed designers are going to use the 2 engine immediately, equipped with a common air intake. The first of these is a completely ordinary jet engine, which will be used from the moment the plane takes off until the speed in Mach 3 takes off. Starting from this airspeed, the aircraft will switch to flying on the scramjet.

Lockheed Martin SR-71 Blackbird

However, the biggest difference from its predecessor will not be this, but that the SR-72 reconnaissance aircraft can be used without a pilot. Currently, the 2 version of the aircraft is being considered - unmanned and manned. At the same time, the aircraft will also be able to carry an offensive weapons complex. Reported that weaponwhich can be used from the SR-72, may be shown by Lockheed Martin in the 2018 year. This, mainly, is about new lightweight missiles, since when launched at 6 flight speed, Mach will not need accelerating and, therefore, heavier stuffing.

One of the tasks of the new hypersonic SR-72 aircraft will be not only to provide the United States with the necessary intelligence information, but also to increase the military power of the state. According to the head of Hypersonics program Bred Leland, hypersonic aircraft armed with hypersonic missiles will be able to penetrate into the airspace of a potential enemy and launch missile strikes in any part of the continent, having reached their destination in less than 1 hour. According to the expert, it is speed that should become the next key indicator in the whole world aviation new generation. Speed ​​will remain a priority over the next few decades. Leland believes that these technologies will be the same turning point, requiring a change in the "rules of the game", which at the time was the massive introduction of technology like "stealth".

According to Brad Leland, the SR-72 at 6 speed of flight Machs will be able to leave to potential opponents of the United States not only a minimum of time to carry out a response, but also to surprise them with high-performance indicators when using hypersonic missiles. Since their launch does not require a launch vehicle, the speed of such missiles will be able to exceed the speed of sound by 6 times, and the design of the missiles will be much easier. And not only in terms of weight, but also in terms of the very structure of the rocket.

The heart of the new aircraft should be, as Lockheed calls it, a turbine based on a combined work cycle. It will combine the technology of the HTV-2 “hypersonic aircraft” engine, which could develop flight speed in 20 Mach (about 24 500 km / h) during the tests. It is reported that the SR-72 will get the 2 engine, each of which, in fact, will be double. Each engine will use a rather complex combined structure consisting of a nozzle and air intakes connected to two different power sources, which will make it possible to achieve a significant reduction in air drag. Lockheed and Aerojet Rocketdyne spent the entire 7 years working together to work out the design of future engines and their appearance. As part of the work on this project, the engineers of the two companies broke their heads many times over finding a suitable solution.

In an interview with the well-known Aviation Week weekly, Brad Leland explained that the cancellation of the Blackbird left a rather impressive gap in the development of satellite technologies (this is not hardware, but hardware), as well as subsonic unmanned and manned systems. Creating a new hypersonic aircraft SR-72 is designed to close this gap. The journal article states that one of the conditions for the creation of the SR-72 is to take into account the requirements of the US Department of Defense as part of its weapons development and research programs. These requirements largely dictate to Lockheed engineers various aspects of the project and its deadlines.

According to Leland, the construction of the SR-72 does not require the creation of fundamentally new technologies, so the flight of the demonstrator aircraft may occur by the 2018 year. In this case, the arrival of a multipurpose aircraft for service is scheduled for the 2030 year.

Question: how to open a bomb bay on hypersound?

Voshchepe, an ento reconnaissance aircraft, is by no means a bomber.
I'm more interested in fuel for its hyper engines. As you know, the predecessor had big problems with the tightness of the fuel system - the fuel was superfluid, and even poisonous in addition. So immediate departure was impossible (a refueled plane formed a poisonous and corrosive surface under a puddle), careful preparation was required. To achieve hypersound, a no less toxic mixture will be used, apparently. So - unprecedented success for the operators and unheard of health to others.

[FID]

Fuel was not superfluid. There were gaps in the case for thermal expansion - flying at supersonic sounds was a high temperature (our Mig-31 had a decent cooling system). But Thrush, after reaching supersonic, became airtight. Something like this ... And as for the bomber - I didn’t come up with it - it’s written in the article ...

In order to launch rockets on super-sound, you need something like a torpedo tube, only in this case the rocket must be faster than the plane, or participate in the design of the airframe, for example, two underwing (wing) influxes, which will be missiles, but should also be faster than the plane and run synchronously. This is all for example! But it seems that to solve the problem of launching rockets on super-sound is not very difficult. Even a simple detachment with a guide above the wing, followed by the launch of the main engine of the rocket can work;) But still this is a scout, not a bomber.

I read, if I’m not mistaken, that preparing the SR-71 for the flight took several days, with a total number of participants up to hundreds. Apparently this plane will need to be prepared for the flight for a month. The analogy of the Space Shuttle. This one only flies lower. The ideas of the German scientist Singer live and find their followers. Oh, how they want to bomb us from near space heights (stratosphere). Straight namietsya. Nothing, let's deal with this.

I read, if I'm not mistaken, that the preparation of the SR-71 for the flight took several days, with a total number of participants up to a hundred. <...>

The division in which I served in the 1979-1981gg (Leningrad Separate Air Defense Army, S-75) worked on thrushes. I was just a lump of the calculation of the SEC, I saw flashes from it on the screen of my locator. Blackbirds flew from the English airfield, then along our borders and landed at the Germans on Schleswig-Holstein. Then in reverse order. They did exactly two flights a week, there and back. It just turns out that it would take three or four days to prepare it.
I don’t know exactly what the chip is there (and no one except their technicians and engineers knows), it is quite possible that the engine resource was small. He had a cruising speed of about 2,4M, and in a short acceleration / afterburner 3,6М.
I read that initially they just wanted to use it as a strategic bomber, but it was with the placement of weapons while maintaining high-speed characteristics that they didn’t succeed. It was written that the main cost of the aircraft fell on the outer surface of the airframe, since there the temperature conditions were completely not for children.

Oh, how they want to bomb us from near space heights (stratosphere). Straight namietsya. Nothing, let's deal with this.

This is not a problem at all. C-400 confidently hits the target, with such characteristics.
Moreover, such a strategist justifies himself little, since with the existing means of air defense, already no heights and speeds give a gain. Winning gives only high-precision weapons with a large radius of action, so as not to enter the air defense zone at all. The main trend now is not hypersonic bombers, but hypersonic cruise missiles. Even if such a missile can reach hypersound when directly approaching the target (entering the air defense zone) at low altitude, this can create a serious headache for any enemy. And if it will fly all the flight at such a speed, then even more so. The latter is unlikely, if not at high altitude and subsequent decrease (the same problems with resistance at low altitude and, accordingly, heating).

[qwert]

I served in air defense in Vladivostok. Worked on Thrushes until the 1988 year. Then our team received the C-300 and the SR flights stopped. The brigade was just blocking the entire Primorsky Territory, the SR area of ​​operations from Japanese bases.
And they really flew on a schedule Tuesday-Friday. Somewhere hours in 11.
The speed of the rocket C-300 - 5 max. It was difficult for him to leave. And with its maneuverability, it’s impossible.

[Falcon5555]

So how did they violate the border?
Someone claimed that they cut corners sometimes.

What is the speed and height of the C-400?
Anton. Think what you write.

The maximum speed of the target for which Triumph can work is 4800m / s. Remember the first class arithmetic course. At worst, take a calculator.
Okay, I’ll help. If you count it on km / h, it turns out 17800km / h. What is hypersound? This is more than half of the first space (7,9km / s).

Practical ceiling at C-400 - 30km. The plane simply does not fly above, since there is almost no air there. Neither for the engine, nor for the glider. The thrush climbed to such heights in a dynamic mode (slide afterburner), almost like a rocket and could be there for a few minutes, if not seconds.

The first is to open the bomb gate and launch a lightweight rocket, But if the speed is very high then? how will bombing take place then? shooting tapes? and the rocket, it will burn, especially since it will be lightweight, although mattress covers may achieve good results but certainly not in the near future.

I can’t imagine how you can open the hatch in hypersound (I studied at the Moscow Aviation Institute at the 1 design factor, worked at the Yakovlev Design Bureau, I know something). And the point is not even in the mechanism of opening the valves, but in the fact that the aerodynamic properties of the airframe will fall by orders of magnitude and there begin such strength and temperature problems that ....
The only way is to make weapons as part of an aerodynamic design. But even here there are a lot of questions on the development of weapons suspension units.

But the hatches ... no. In hypersound, this topic does not work.

[Cosmos1987]

but what if the doors are made to not open outward, for example sliding ones, so that they go into the glider of an airplane or come off inwards using tram doors as an example, and place the hatch in a niche so that the stream does not get inside.

It does not matter. Of importance is the deterioration in the aerodynamic quality of the entire structure, the enormous pressure and temperature in the open hatch area.
Niches as such can no longer be. Again for aerodynamics reasons. The thrush with its three and a half strokes and then like a needle, and our MIG-25 are just two solid engines and made of stainless steel. And what will happen at speed in 6 is even scary to imagine.

[qwert]

Any aircraft flying in hypersound is inside an ionized gas — practically inside a plasma. This makes the device invisible to locators, since the plasma absorbs radio waves. Those. with this parameter, the scout will be in openwork. However, he will not be able to conduct radar reconnaissance, electronic intelligence, and so on. Only optical reconnaissance is possible, i.e. a photo. So what? Of course, for the forties it would be very wonderful, but now it is very little. And satellites can conduct it no less badly, and at the same time without any restrictions. Moreover, it should be remembered that even on the SR-71, terribly expensive fuel was used, and ground handling of one SR was comparable to servicing the wing of tactical fighters. Therefore, satellite reconnaissance is probably cheaper than anything else. Therefore, it is not entirely clear to me as an engineer what the Americans want to get in the new device? Well, of course, maneuverability. On SR-71, she was within 2g. no anti-missile maneuvers can be discussed here.

I want to once again show a photograph of a blackbird and so that people would understand that this is an airplane that flew "only" at a speed of 3600 km / h. I mean aerodynamics. Those. everything has been done to reduce the heat load. Starting with the contours and ending with a special coating that evenly distributed the heating of the airframe over its entire area.

[9lvariag]

So where is the detachable capsule in the cab? We look at the legendary Lou Schalk in the cockpit, A-11. There is not even a place to unfold. And in other pictures from the resource it is clearly visible that there is not even a thermal protection of the cabin.

What it looks like "hvantastika". I’m wondering if they’re so smart why they don’t go in formation, they still fly the B-52, and what material will be used for the skin on their new fashionable plane. I am not talking about the price, they cannot reanimate the shuttles, there is not enough money. If we were talking about the study of space, one can still understand: a lot of money is pouring in - but this is space! And as for a scout ... In general, Americans are good science fiction writers and films in Hollywood shoot well. Probably Lockheed Martin decided to wash the dough again! Their experience in this matter of laundering is high!

[qwert]

They said about the coating that technologies will be used for the first time applied at the Shuttles. I must say there the coating is quite soft and each unit is individual and has its own passport. Those. it is facing with bricks which, for example, cannot be stepped on even barefoot. Something like this.

Yes, there are no two modes! There is an ordinary engine turbofan engine. And an awesome intake path! 2 times longer than the engine! And a large ramjet, in the form of windows over the descent and fence and a pile of dampers and a large afterburner. So what? Took off , scored 700-800km / h, pressed the autopilot, the device scored 8000m. and 1,5M. Then he turned off 50 tons of fuel, turned on the autopilot and scored 20000 m. and 2.7M or 3,2M.

[qwert]

When I read about the SR-71 I always remember and proud of the MiG-25. SR-71 was created as a heavy three-swing fighter. It was not possible to provide the necessary maneuverability while maintaining range. The ability to maneuver with overloads necessitates strengthening the structure, i.e. to make heavier. In addition, the aircraft cost was beyond the scope applicable to fighters. Well, the duration of preparation for the departure and the need to develop infrastructure, including production in the required quantities of special fuel, put an end to the super-fast fighter. In those same years, in the USSR they managed to create a three-swing heavy fighter with maneuverable characteristics acceptable for an interceptor. Moreover, almost without the use of expensive titanium floats, but from stainless steel, and in addition with engines running on the usual varieties of jet fuel. The only thing inferior to the MIG-25 is its flight range. But at the same time he could combine intelligence functions with drums. And the price of the MiG was ... Well, not at all futuristic)))) In a word, we created a good workhorse, and in the USA an aircraft concept car. It always pleases when by more simple means it was possible to achieve better results.

[Al_lexx]

Edward, + 1 to you in karma.

I also always recall MIG-25 when graters about a thrush begin. :)
Minimally inferior to the thrush in speed and ceiling, the twenty-fifth was still a full-fledged interceptor.
By the way, our fox was developed as a response to the American thrush and promising attack aircraft with similar characteristics. Shock amers failed to do. But we managed to make the MIG-31, which is still considered an unsurpassed air defense system. Even the Americans themselves admit that the only plane that can compete on equal terms with the F-22 is our 31. The only thing the American surpasses him in is radio stealth. And in all the rest it is inferior.

With the modern development of air-to-air missiles, close combat is extremely unlikely.
It’s about how to argue that a heavy tank with a powerful gun is less maneuverable than light. Easy to him simply will not reach.

Let's just say that in modern aerial combat, high maneuverability is undoubtedly a very useful bonus, but not the characteristic that gives a decisive advantage. Decisive are the detection distance minus radio visibility, the launch range and the probability of hitting a single missile. Close integration with global aerial reconnaissance and other airborne vehicles is also considered important.

Who told you this? Believe them more? Even without you (I’m not even a fighter pilot), I know that in the 70s I was beckoning, does not teach combat pilots even aerobatics, in schools! And some people normally paid for it with their lives. What we have is unsurpassed in piloting SU-47, SU-30MKI.

Let's just say that in modern aerial combat, high maneuverability is undoubtedly a very useful bonus, but not the characteristic that gives a decisive advantage.

Well, yes, the crew, MiG-25 in Syria, on which the F-16 rocket was launched, did not think so. If they had not applied. braking with a sharp maneuver and then afterburner - it would have long ago rotted in a foreign land - in the ground! And about leaving, on an over maneuver from MANPADS, and MZA - I am silent. Where, then I read that in Yugoslavia, one of their flyers managed to leave for AN-2, from 7 MANPADS missiles. And here you are soaring, all for STELT, the technologies that destroyed the A-12 and the CP-71 itself and made with the F-117, such a refuge that is not in a fairy tale. And what about what happens if the location goes into the 100 MHz band and radars are lifted into space? Then any rivet and crack will be visible to the radars.

[9lvariag]

Well, in the USA, when they were making the XB-70, they calculated how many "Baku" ones would be needed to make the "Valkyrie" from titanium alloys. So it turned out that the price of one bomber for the USAF went off scale there were several billions. It was easier to slap the new atomic "Nimitz". And there really were no targets for such an aircraft! And the need for it too. Therefore, only a few aircraft were built, without bombing equipment, especially since 2 aircraft in general with a crew, not a regular 4 people, but only 2 pilots - this is for NASA. The intrigue of all was that it was found that it was impossible to create an aeroelastic structure from such alloys. And therefore the XB-70 airframe was also welded with laminated panels from corrugation (similar to packaging) with special heat-resistant stainless steel, to the ABC-360 type. How they bent her there FIG knows. And then during the tests, the bomber tore pieces of the skin. In 1 sq. m.

However, the use of reconnaissance satellites is not the most ideal of all possible solutions. Modern reconnaissance satellites are able to receive very detailed high-quality photographs of various terrestrial objects, but they require significant time in order to redirect the device, transferring it to another orbit. The satellite is not alone in the United States; there can be 3 dozen f-35s; the program is 100 mln; but how much does the sr-72 program cost in 50 years and there will be something worse but not in the near future

Yes, but at the time when "A-12" and "SR-71" were working, the satellite camera coverage was only 5 km! And cameras and movies. these aircraft were panoramic and covered the entire 15-30 km. width, this is at 1980 and 1000m. film in a reel. It was not for nothing that they wrote that it was the "Archangel" who filmed the bombing of Libya. A satellite would have done it in 1 month! We do not believe we go to http://www.testpilot.ru/usa/lockheed/a/12/a12_test.htm and habu.org and carefully study the materials.

Amendment to the post:

This was preceded by major controversies between the CIA, the Air Force, the State Department and the US Budget Commission. In light of the declining defense spending, it was considered wasteful to fund both the CIA's 10 A-12 reconnaissance fleet and the 30 SR-71 Air Force's fleet. During the discussion on November 3, 1967, a comparative Nice Girl operation was even performed. During it, the A-12 and SR-71 flew along the same route from north to south along the Mississippi. The Type I A-12 was noted to provide 72 miles of coverage with 1500m film headroom versus Operational Objective camera's SR-28A's 71-mile footage (990m film stock). At the same time, the presence of side-looking radar, infrared and ELINT / COMINT equipment gave the SR-71A qualitatively different reconnaissance capabilities.

And the second question is, does the engine with a variable thrust vector be used on missiles?

Question: how to open a bomb bay on hypersound?

Voshchepe, an ento reconnaissance aircraft, is by no means a bomber.
I'm more interested in fuel for its hyper engines. As you know, the predecessor had big problems with the tightness of the fuel system - the fuel was superfluid, and even poisonous in addition. So immediate departure was impossible (a refueled plane formed a poisonous and corrosive surface under a puddle), careful preparation was required. To achieve hypersound, a no less toxic mixture will be used, apparently. So - unprecedented success for the operators and unheard of health to others.

As you know, a strategic modification of the SR-71, RB-12 / 71A was developed! And they even sought from McNamara to launch her into series, but then the Valkyrie XB-70 was already being tested. And Lockheed offered to choose either a lot of A-11 & SR-71A / S, or nifiga scouts and satellites from the USAF Air Force! And the subject of the article is apparently the mythical "Aurora", which has been periodically steamed up from the 70s, after the inglorious death of the XB-20 "Dinosaur". It's just not clear why, um, such planes? Any radar and maneuverability will see them on the trail of a jump and plasma from a dvigla, nor any - a bend - 90 km. at 3M! And at the same time, the Y / A-12 hull also bent, in the bow by 15 cm! The entire fuselage was floating. So much for your leaks. We will also add constant control problems and complexity to the ships. And what about the problems with the automatic equipment on the afterburner, that there were no fires? The presence of a heavy load on the crew. Constant failures of the APU. Complexity of maintenance and repair (all damaged aircraft were no longer restored). On the most complex automation of air intake and in general ... this is the biggest problem of the Archangels engines. And after 3,3M. in them already began a massive surge! Why does the Russian Federation need such aircraft

I read, if I’m not mistaken, that preparing the SR-71 for the flight took several days, with a total number of participants up to hundreds. Apparently this plane will need to be prepared for the flight for a month. The analogy of the Space Shuttle. This one only flies lower. The ideas of the German scientist Singer live and find their followers. Oh, how they want to bomb us from near space heights (stratosphere). Straight namietsya. Nothing, let's deal with this.

189 hours after the flight! And the flight itself cost the price THINK - $ 8mln! It costs 1962 - 71 years! Such an eternal cut of the US budget!

To reduce risks, it is necessary to focus on improving the production methods of aircraft. So, in the spring, the main elements of the shell-case were developed, and also elements of the thermal protection system made using various materials and with the involvement of specialized subcontractors were tested. For example, the nose and leading edges were made of CM based on carbon reinforced with carbon fiber for long-term operation at 16.500 ° C (Pratt and Whitney); KMs with reflective properties were developed that retain strength at 19.800 ° C (Physical Science, Composite Innovations, ATK); multilayer heat-shielding materials (Refrector); lamellar heat-protective materials and heat-resistant compounds. The nose and leading edges were subjected to fire tests in the ADT with arc heating at the NASA them. Ames.

Three years ago, the U.S. Air Force inadvertently admitted that a hypersonic X-51A with a ramjet with supersonic combustion is just an impossible dream.

And even earlier, the French gave out the main "secret" in this matter - "materials are required for continuous operation at 16.500 ° C - 19.800 ° C" - everyone is resting.

SR-72 - "lure" to take Russia to the edge.

And the efforts of the Americans are already beginning to bear the first “rewards” encouraging them.

Four decades earlier, the US president instructed his assistant to look into the possibility of creating a hypersonic transport aircraft.

The United States has not returned to this issue.

Project P.O. Dry T-4 was designed for M = 3. However, it turned out that there were errors in the thermal calculations. The built aircraft received a speed limit of 1.700 km / h. Chief Designer T-4 N.S. Chernyakov, as soon as he found out about this, personally immediately fired the chief of the brigade responsible for thermal calculations.

Hypersound for conventional missiles is a common thing, because it is short-lived.
According to the magazine Air et Cosmos, missiles of the S-400 complex develop a speed of M = 9.
The maximum speed of SM-3 Block IA missiles reaches 3–3,5 km / s - M = 10–12.

"Materiel" must be taught and not be aroused in vain.

But it seems to me that such hooks no longer work. It was possible in the 70s-80s to "take on the arap", but now many technologies have approached certain borders and these border areas are well researched.

I want to once again show a photograph of a blackbird and so that people would understand that this is an airplane that flew "only" at a speed of 3600 km / h. I mean aerodynamics. Those. everything has been done to reduce the heat load. Starting with the contours and ending with a special coating that evenly distributed the heating of the airframe over its entire area.

Open

The absolute speed record was set by captain Eldon Jorz and Major George Morgan - 3 529,56 km / h! All records were set on the SR-71A, owned by the 9th SRW.

Where is the 3600? Moreover, after this speed of air jumps from the bow, it already got into the engine’s drive and massive surge began. To whom to whom, and Lou Schalke. not to tell you about this phenomenon! Like about not starting, ramjet at a speed of 2M. And there was no capsule under the lamp, but there was an ordinary spacesuit with an analogue of TCEs! And there was not, nor any, coatings for thermal unloading. And there was a radio absorbing structure based on carbon fabric and graphite. And furthermore, Y / A -12 themselves had

Lateral influxes on the A-12 aircraft performed not only the role of destabilizers of small elongation, but also increased stability in the yaw channel. The decrease in the area of ​​sagging on the YF-12 reduced the already small margin of track stability; in order to keep it at the same level, the interceptor had to be equipped with a folding central ventral keel and two vertical surfaces smaller than the central keel of the area. The central keel when the landing gear was folded to the left to provide an acceptable "ground clearance" (a similar system was used on the MiG-23 fighter).

Fresh food, but sowing with difficulty! Question: how to open a bomb bay on hypersound? Sliding sashes? But the volume of the bomb bay opens, where the hypersonic stream of air will enter ... Heh, heh, heh ...

Not like that, mod. this aircraft under a bomber and all that requires air conditioning in the weapons compartment. This is for JBCH! Do not you have not read on the topic ...? But essentially, you should turn to project materials[media = http: //www.testpilot.ru/usa/other/aurora/aurora.htm] and RB-12 / And also Nort American XB-70 Valkyrie ("Valkyrie") - there the bomb bay was placed in the aerodynamic shadow, behind the air intake of the engines. It is also possible to dump back, as on torpedo boats that had aft equipment, gunpowder or any catapult. Although I doubt that such aircraft at modern. the nuclear warhead dimensions, in the FAB 250/500 format, will be gigantic, as on TU -95 and 3MD!

And you read for PKU, the A / Y - 12 fighter, under the GAR-9, if the first tests were carried out with the launch of a rocket, then it would hit right under the operator’s cabin.

I recorded another video, now about RS-72. I tried to collect everything that is on the topic.

[9lvariag]

Becoming I am not complete and not analytical material. The author Sergey Yuferev, simply copied it from other articles and resources. Where is the material about Tupolev-Lavochkin "Hawk", the Soviet reconnaissance and strike UAV with a 2MT thermonuclear warhead? Where is the material about the clear predecessor of this rasp? About the Lockheed GTD-21, the forerunner of all US drones? In this article, he is not even casually mentioned! But this one-time titanium UAV, and the speed developed more than the A-12 and was better in design and aerodynamics than the SR-71. And UAV intelligence, relate more. Although if you take the A-12 and Y / A-12, they are really airplanes. And SR, the plane was only due to a misunderstanding and because its pilot refuel in the air and take off. And no more. All conclusions, however, are more than doubtful. If the photo is reconnaissance, it can still conduct, then video reconnaissance, and even more so in the IR range due to the plasma cone, is unlikely to succeed. It is unlikely to be able to carry out RTR - reconnaissance. And for dropping missiles and even more so bombs, speed is needed no more than 2,7M. on such things, with a clear overexpenditure of fuel, no one will lead. Now is not the time for the Space Shuttle and the old hemp from the General Staff of the USSR and the Politburo of the CPSU Central Committee.

The only way is to make weapons as part of the aerodynamic design

Shoot part of the fuselage, part of the tail or wing flips, for example? And so that the rest could still fly? Damn hard. But it is tempting.

Yes, they shot already, all this is already shaggy and complex.
