Military Review

The Ludwig Trumpet remains relevant: in the USA they talked about the research of hypersonic motion

76

Employees of the University of San Antonio (Texas, USA) and the American Southwest Research Institute received an order to study the movement of objects at hypersonic speeds. According to the latest information, these studies were ordered by the US military, which is going to receive a hypersonic weapon.


The work is carried out in the laboratory under the direction of Christopher Combs and Nicholas Muchke.

Nicholas Muchke:

The goal is to ultimately make full aerodynamic measurements in a truly representative hypersonic environment. These measurements will help develop the next generation of hypersonic objects.

It is noted that an important phase of the study is that associated with the study of the parameters of air that comes into contact with an object moving at a speed of more than Mach 5 (this is hypersonic speed). The researchers remind that at such speeds of the object, the air in contact with it begins to disintegrate into molecules, which can later be built into new compounds. Thus, the decomposition of air into nitrogen and oxygen molecules is noted, which are arranged in various configurations at high temperatures.

The researchers described the method:

We carried out the first stage of research in a mechanical engineering laboratory using a two-stage system of light gas cannons, which simulates hypersonic flight conditions and allows images of objects in hypersonic flight. When we launch an object at hypersonic speeds, the air around it begins to collapse. The resulting temperature can exceed the surface temperature of the sun. A configuration is being built, the parameters of which allow us to track the laser beams that we aim at what used to be an air mass.



It is noted that the medium formed during the flight of an object at hypersonic speeds absorbs laser radiation more intensively. Then there is a glow of different wavelengths. On this basis, as stated, it is possible to build mathematical and physical models of hypersonic motion, which will allow the selection of suitable materials for effective flight at hypersonic speeds.

From Christopher Combs' statement:

We hope to measure the pressure, temperature and density of the environment, which will ultimately lead to a truly representative picture of a hypersonic flight environment that is extremely difficult to study in real conditions.

It is noted that some of the experiments are carried out in a Ludwig tube with a high-speed diaphragm. The maximum speeds for which the experiments were carried out in the American laboratory were 6-7 M. It is noteworthy that the Ludwig tube is far from a supermodern invention. It was developed in Germany in the mid-1950s. It conducted experiments to model the "behavior" of aircraft parts in different countries, in terms of turbulence. Judging by the statements of American scientists, the Ludwig tube does not lose its relevance even with modern research in the field of hypersound.

    Everything new is well forgotten old. This is not surprising, because scientific thought is always ahead of technological capabilities. Whether it will be possible to catch up now is not a fact.

          Let everything remain so. The Americans already think about themselves, but with hypersonic weapons they will go completely crazy. Let's save their nerves. Let them remain at the stage of exceptional and do not go to the stage of crazy.

              They also have been flying and flying for a long time, there is research to reduce the cost of development in the field of hypersound.
              The X-15 (Russian "X-15") is an experimental US rocket plane. The first manned hypersonic aircraft to perform suborbital manned space flights. The first reusable spacecraft. The main objective of the X-15 project is to study the possibility of creating a manned suborbital hypersonic bomber [1] X-20 Dyna Soar. For the study of flight at hypersonic speeds and the entry into the atmosphere of winged vehicles, assessment of design solutions, heat-shielding coatings, psychophysiology during control in the upper atmosphere.

          Which of the following has reached the stage of state testing in the United States, and not yet another attempt to create a hypersonic weapon that has encountered an insurmountable obstacle and therefore has not been brought to its logical conclusion? Then we can recall the experimental hypersonic apparatus X-90 Koala, which never got up for service. The same Bolide, although not hypersonic here. The American X-51 was never brought to a working sample.
          I’m wondering for you the secret weapon of the Russian Federation is a reality, but the same American weapon is a bluff?

          GZUR and Zircon entered the stage of state tests. And what kind of hypersonic weapons and prototypes for the Americans have entered the stage of real state tests and are close to being adopted? An experimental prototype and a real combat-ready weapon put into service are two different things. I don’t deny that the Americans have some kind of experience, But this is not a weapon that has passed state testing, but experimental raw samples, attempts to create such a weapon.

                  Is the PrSM project the norm in your words? Do not confuse conventional MIRVs with gliding hypersonic gliders like the Ju-71, they are much more difficult to intercept. PrSM is something like the Avangard ICBM complex with the Ju-71, only the Americans have MRBM glider.

                    Do not confuse strategic and tactical missiles.
                    PrSM is a tactical missile launched from the standard US M-270 multiple launch rocket system.
                    And the Ju-71 is the nuclear mother of its warhead, which falls from the Stiletto ICBM. A huge rocket drone starting from a mine deep in the country.

                      The US Army is already developing an entirely new "Precision Strike Missile" (PRSM). So far, it is designed to engage targets at a distance of up to 499 km, but, as American officers admit, this limit was set deliberately in order not to violate the INF Treaty. The technology used in this missile system has a certain modernization potential.

                        Well, one more time. PRSM is a tactical missile, the troops spat and threw it into the headquarters.
                        And the Ju-71 is a nuclear bomb that falls from an ICBM, that is, a strategic weapon. All of these nuclear bombs falling from ICBMs are hypersonic. Its novelty is only in controllability. Moreover, the novelty is only for Russia, since the United States put controlled warheads on Pershing.

              Everyone confuses the flight at the GPZ speed and the achievement of the GPZ speed.
              The first object manufactured to achieve hypersonic flight was the RTV-G-4 Bumper two-stage rocket, consisting of a WAC Corporal second stage mounted on the base of the V-2 first stage. In February 1949, in White Sands, the rocket accelerated to 8 km / h (approximately Mach 288,12). However, it burned up on re-entry into the atmosphere, and only charred remains were found.

              At the entry into the atmosphere at an altitude of over 100 km, the BR warheads have hypersound, and at the final section, subsonic speed. A hypersonic aircraft must fly at hypersonic speed, at least in the stratosphere at high altitudes.

            Horizontal movement on hypersound in the dense layers of the atmosphere is what the Americans are researching.
            And all the weapons that have been put into service in recent years are hypersonic movement in space, or rather, glider glide from space (Vanguard) or at altitudes of 40-50 km (Dagger, Zircon).

                  in this case nothing is inhibited by friction. This is not the usual aerodynamic drag in the boundary layer. Heats up from friction. Braking from the resistance of the medium, because on the NW, a super-dense layer appears in front of the warhead cone. And the recipes here are the same - we reduce the midsection, increase the aerodynamic flow, reduce the resistance of the medium and, as a result, heating.

      Think you got Uncle Sam's ass covered? Well done.
      Only you read the article? It clearly states that the Americans are beginning to re-comprehend the basics of hypersound. And the data you cited do not say anything at all. The experimental vehicles were not brought to their logical conclusion, the creation of a combat-ready model of hypersonic weapons. Just once upon a time they pampered and abandoned experiments, because it did not work out. As with us at one time with the X-90 Koala, the dimensions of the product did not suit. Now a new technological base, new approaches, here, starting from them, they are trying to come up with something sensible, starting from the very beginning.

        I read the article, the article is shit (even the author hesitates to identify himself)
        2016: Purdue University in the United States commissions a Boeing / AFOSR Mach 6 Quiet Tunnel, a "silent" and inexpensive wind tunnel, allowing the study of hypersonic vehicles in laminar flow at Mach 6. The facility, which was funded by the US Air Force Research and Development Agency, the Anti-Missile Defense Agency, and Boeing, was completed in 1, but took another four years to refine, remediate and test.
        Boeing / AFOSR Mach 6 Quiet Tunnel is not the first wind tunnel with similar characteristics - similar to NASAhowever, that is currently not in operation.

        Since 1992, a similar wind tunnel according to the Ludwig scheme, designed for a speed of Mach 4, has been operating at the University of Purdue.

      About intelligibly. In the late 1930s, all information on research into the decay of the nucleus, uranium, etc., disappeared from the open scientific press of the West. As a result, based on such facts, our intelligence came to confirm the US nuclear weapons developments. I think the methods have changed little today. If something is publicly available, it is unlikely that it is a big break and not a distraction.

    Everything new is well forgotten old.

    Forgotten with a fig? Hypersonic pipes, including Ludwig's, have worked and are working both here and in the center of Langley, in ONERA, and in many other places where there are high-enthalpy installations. The material was written by a journalist who does not even know about the molecular oxygen formed in the compressed layer, and about other routine matters. The journalist calls the thermal spectrum of dense plasma "the glow of different wavelengths." The two-stage "system of light-gas cannons" has nothing to do with Ludwig's pipe, these systems in the world, too, "like flies in the toilet" (L. Filatov). In particular, one light gas cannon is located at the Institute of Mechanics of Moscow State University, the first stage there is based on a 100 mm anti-aircraft gun KS-10. Nice setup. Judging by the text, the temperature (rotational) at the installation is determined by the adsorption spectral method (if the density is high, then the simpler emission does not pass). In general, there are enough problems.

    We hope to measure the pressure, temperature and density of the environment, which will ultimately lead to a truly representative picture of a hypersonic flight environment that is extremely difficult to study in real conditions.

            glider layout - with such a midship, it is unlikely to go to supersonic= scoop
            Engine - air intake (we do not see the engine)
            Therefore, a model was developed and manufactured convergent air intake, which had a section of spatial external compression, a section of internal compression and an internal channel of a trapezoidal cross-section with "notch" 90. The external compression surface consists of an initial internal cone and a contour with additional curvature to increase the compression ratio.


            Such a shape and location practically does not imply an angle of attack, only a dive?

    And the United States did not just screw it up, they, forgive my French again, did it very fluidly. In general, if we discard all the operational-tactical and technological components, about which the majority of "Xperds" in Russia simply either did not want to talk or simply did not know what was most likely, then the story is essentially biblical. David and Goliath. Goliath was a classic Philistine gopnik and impudent who, among other things, had a crowd of the same as he, only smaller in stature, and spread his fingers at the Israelites and kind of demanded seeds and a phone. David was small, much smaller than Goliath (according to the Bible, he was there something over 3 meters tall) and seeing that the Israelites somehow did not really want to fight, but they did not want to give the seeds and the phone either, he formulated a wonderful operational tactical wisdom that Goliath, of course, was huge, but the harder it was to miss him. You all know the rest, Goliath naturally received a winged ra in his forehead .... sorry, with a stone released from David's sling, he collapsed, David finished him off with a sword and cut off his boss. Seeing all this, the Philistine gopniks fled, the Israelites not only saved the seeds and the phone, but also won, and then they had a disco. laughing
