Ajax Hypersonic Multi-Purpose Aircraft

The concept of a fundamentally new hypersonic device was put forward at the end of the 80s. Vladimir Lvovich Freistadt, working in the St. Petersburg Scientific-Research Enterprise of Hypersonic Systems (NIPGS) of the holding company Leninets. He proposed not to protect the device, flying at a tremendous speed, from heat, but, on the contrary, to let it in to increase the energy resource. According to the Ajax concept, a hypersonic aircraft (GLA) is an open non-isolated aerothermodynamic system in which at all stages of atmospheric flight some of the kinetic energy of the flowing HVA hypersonic air flow is assimilated by the onboard subsystems, increasing the overall life of the device and transforming into chemical and electrical energy. This solved the global issue of cooling the airframe and many other problems.

Initially, Ajax was created as a response to the American plans to create an Aurora hypersonic reconnaissance aircraft, later it was “converted” into a hypersonic global-range aircraft or the first stage to put the payload into orbit.

Hypersonic LA uses hydrocarbons (kerosene or more promising fuel - liquefied methane) and water as fuel. For heat recovery, a thermochemical reactor is placed in the Ajax double skin, in which, after acceleration and aerodynamic heating of the skin, hydrocarbon fuel is supplied. It is used as "endothermic" fuel - absorbs heat. Under the action of temperature, pressure and with the help of a catalyst, the fuel / water mixture is decomposed into olefin and free hydrogen. This hydrogen-containing mixture enters the magnetic-plasma-chemical engine, which is an MHD generator, a hypersonic ramjet, and an MHD accelerator behind the combustion chamber. MHD generator, braking the flow to the optimum speed, acts as a compressor. Inhibited and pre-ionized air flow enters the combustion chamber, which is supplied with hydrogen-rich fuel (kerosene or methane). The effluent combustion products enter the nozzle, are additionally accelerated by the MHD accelerator and, expanding, exit to the outside. To accelerate the flow and to ionize the air - creating a "cold plasma" - uses electricity generated by the MHD generator. This allows you to increase the speed of the aircraft on 10-30% and get a number of advantages. The plasma funnel around the scramjet air intake increases its effective diameter up to almost a hundred meters, plasma spots-clouds in front of the aircraft significantly reduce air resistance, and near the wings increase their effective area and regulate lift. For the ionization of air, it is possible to use laser radiation or a neutron source.

Thus, the device flying in the atmosphere will be able to convert the kinetic energy of the incoming air flow into a wide range of different types of energy and use the onboard power complex with a power of 100 MW for the most varied planetary tasks. Based on the Ajax concept, GNIPGS developed a family of hypersonic LA “Neva” for the near-earth or orbital transportation of payloads or passengers.

The revolutionary concept of “Ajax” has a large coefficient of novelty, and therefore technical risk. Only by 1993, the expert committee of the largest scientists made the final verdict: "The concept of" Ajax "and its main areas do not contradict the data of modern science." In the same year, a meeting of the Scientific and Technical Council of the State Committee on Defense Industry was held.

The NIPSS, headed by Director General Alexander Leonidovich Kuranov, is actively promoting the concept and is looking for sources of financing for its implementation. And in May 2001, the press service of the holding announced that the Leninets Holding Company OJSC (St. Petersburg) signed an agreement with China on joint work on a hypersonic aircraft (Ajax concept). The project is designed for 10-15 The volume of investments has not yet been determined, but, according to experts, about 70-80 million dollars are spent on the development of such a project abroad. According to the press service of Leninets, the parties plan to sign financial documents for the project in September 2001. The agreement also provides for cooperation in the field of and development of electronic equipment for various types aviationsatellite navigation systems.

The world's first maneuvering X-90 Koala hypersonic rocket (“AS-19 Koala”).

In February 2004 of the year, during the command and staff exercises of the 2004 Security exercise, in the presence of President Putin, the world's first maneuvering hypersonic missile was successfully tested. New Russian weaponlaunched from strategic bombers Tu-160, must overcome any missile defense system.

Russia, with the help of a new super-weapon, wants to show America its capabilities. It is called X-90 and is the Kremlin’s response to the Washington missile defense program. In the west, the project is known under the harmless name “AS-19 Koala”. Under the designation X-90 hides, according to Russian data, the world's first hypersonic guided cruise missile, the appearance and tactical-technical data of which are military secrets. According to reports, it should be adopted by the 2010 year.

The X-90 is launched with the help of the Tu-160M strategic bombers, which are the symbol of Russian military might. “M” - modified - means in this case that the wings of the machine are enlarged.

According to Putin, X-90 is able to overcome all existing, as well as promising missile defense systems and destroy targets with great accuracy, including on other continents. A prototype of a “miracle weapon” was tested in February 2004 of the year, during the command and control exercises “Security 2004”, in the presence of President Putin, with the PC-18 intercontinental missile (NATO designation SS-19 Stiletto) as a carrier, and in the near future will be in service with the strategic missile forces.

History X-90 began in 1971 year. Then the developers turned to the USSR government with a project to build small strategic cruise missiles that could operate at low altitudes, applying to the terrain. This proposal did not find a response from the leadership at that time, however, after the United States began developing strategic cruise missiles (Cruise Missile) in 1975, they remembered it. Missile developers were ordered to start development in the middle of 1976. It should have ended by the middle of 1982. Already by December 31 1983 rocket supposed to adopt. One of the main requirements was to provide the rocket with supersonic speed.

At the end of 70-x-90 reached the speed of 2,5-3, and in 80-x already 3-4 M. Visitors to the MAKS-1997 air show could admire the experimental hypersonic aircraft GLA.

GLA is the prototype of a new cruise missile. It must carry two individual-targeting warheads that can independently hit targets at a distance of up to 100 km from the point of separation from the main rocket. The Tu-160M bomber is assumed to be the carrier.

Ajax Hypersonic Multi-Purpose AircraftAt that time, the X-90 CHA, equipped with a ramjet engine, was about 12 meters long. The current rocket does not exceed 8-9 meters.

After separation from the carrier aircraft at a height of 7000-20000 meters, a triangular wing with a span of about seven meters, as well as tail tails, opens. Then a solid-fuel accelerator is turned on, which accelerates the rocket to supersonic speed, after which the cruise engine comes into play, providing the speed of 4-5 M. The radius of action is 3500 kilometers.

According to the Kremlin, no state in the world possesses hypersonic rockets. The United States at one time abandoned their development for financial reasons and limited to subsonic. In Russia, work was also carried out inconsistently, but pauses were short. Already in July, 2001, the press reported on the launch of the Topol rocket. Noteworthy was the behavior of the warhead that was unusual for ballistic specialists. Then it was not confirmed that the warhead is equipped with its own engine, allowing it to maneuver in the atmosphere at hypersonic speed. The 2004 teachings of February, which were first mentioned throughout the entire territory of Russia since 1982, turned out to be a real sensation. During these exercises, two ballistic missiles were launched: one Topol-M and one PC-18. As it turned out later, the PC-18 was equipped with some kind of experimental apparatus. He went into space, and then again “dived” into the atmosphere. This maneuver seems at the present level of technology incredible. At the moment the warhead enters the dense atmosphere, its velocity is 5000m / s (approx. 18000 km / h). Therefore, the warhead must have special protection against overloads and overheating. The experimental apparatus had no less speed, however, it easily changed the direction of flight and did not collapse. Miracles in aerodynamics does not happen. American shuttles and the Soviet Buran, modern fighters have common features. Apparently, the unit tested during the exercise is similar to the X-90. To this day, its true appearance is, as already mentioned, a state secret.

"This unit can overcome the regional missile defense system," - said the representative of the General Staff, Colonel-General Yuri Baluevsky at a press conference after the exercise. Unlike the existing ballistic warheads, this device is capable of “changing the flight trajectory at any time in accordance with the program laid down in advance, or it can be redirected to another target over the enemy’s territory”.

Instead of a conventional warhead, which follows a fixed trajectory and can theoretically be intercepted by an antimissile, there was a device on the PC-18 capable of changing the height and direction of flight, and thus overcoming any, including the American, anti-missile system. When asked by journalists how, in his opinion, the United States will respond to this news, President Putin said: "The United States itself is actively developing its own weapon." The President recalled that Washington had recently withdrawn from the ABM Treaty, stating that this step was not directed against the Russian Federation. The modernization of existing and the development of new weapons systems in Russia is also not directed against the United States, President Putin assured, adding: “Together with other states, Russia is responsible for stability and security on the huge Eurasian continent.”

Russia's strategic missile forces include:

3 rocket armies, 16 rocket divisions. They are armed with 735 ballistic missiles with 3159 nuclear warheads. These include 150 Р-36М УТТХ and Р-36М2 “Voyevoda” of mine base (NATO designation of both types SS-18 Satan), carrying 10 independently controlled warheads each, 130 of mine UR-100ТТТX (SS-N-to-to-to-to-S-S-to-S-S-S-S-S-S-S-S-S-S-S-N-N-N-N-N type -GNUMX every-one, 19 shaft-type UR-780 Satan XMNUMXMTTX and P-36М23 “Voyevod” mine) base, each of warheads and 360 RT-360 UTTH “Good for you” with 2 warheads based on railway complexes, 25 mobile monoblock complexes RT-39РМ Topol (SS-2 “Sikl”) and 2 of the latest mono-block PT-systems, which are provided by the IT department of the IT department of the CT department of the IT department of the Center for IT systems, and the 27 of the newest mono-block complex PT-CTnTXNMX and the 2 of the newest mono-block RT-CTnTXNMX (SS-XNUMX "Topol-MXNUMX").

According to Russian experts, equipping even a small part of this arsenal with cruise warheads will make the Russian rocket forces “for decades ahead” invulnerable to any missile defense system. Even George Bush’s upcoming missile defense will turn into a “super-expensive and useless toy”. In addition, Russian experts remind that the hypersonic warhead is not the only development in this direction. There are also programs “Cold” and “Igla” flying laboratory, where the details of the Russian Aerospace Aircraft (RAKS) are tested. All of them may be part of a unified plan for creating a maneuvering warhead that is invulnerable to a promising missile defense system.

The idea of ​​overcoming missile defense systems is in principle not new. Back in 60-ies in the Soviet Union created the project “global rocket”. The idea was to launch a warhead into a near-earth orbit using a booster rocket, where it would turn into an artificial satellite of the Earth. Then, on command, the brake motor was activated, and the warhead was sent to any target for its destruction. At that time, the United States adjusted its missile defense system on the assumption that Soviet missiles would fly up at the shortest distance across the North Pole. As a first-strike weapon, it is difficult to imagine anything better, since global missiles could attack the United States from the south, where the Americans did not have radars to detect incoming missiles and take countermeasures. 19 November 1968, this Soviet system was put into service and in small quantities put on combat duty. At the Baikanur cosmodrome, 18 P-36 orb rockets were deployed. (orbital) mine-based. After the conclusion of the SALT-2 contract banning orbital rockets, the system was dismantled. Although the treaty was not ratified, the USSR and the USA adhered to its terms. In 1982, the dismantling and destruction of the P-36 orb began, which ended by May 1984. Launch complexes were blown up.

Perhaps now, at a new technological level, the system will survive a rebirth. This means that the US missile defense, in which the US is investing tens of billions of dollars, loses its meaning. Therefore, the United States is now starting to deploy radar systems near the Russian borders in order to detect and destroy missiles immediately after launch, before the separation of the warhead.

But for this, according to experts, there are a number of countermeasures, partly developed in the framework of the Soviet program of counteraction of the PIO. So, attempts to intercept can be hampered by the fact that the rocket, in the active phase of flight, performs an orbital maneuver. For example, the Topol-M rocket, according to the statement of its General Designer Yu.Solomonov, can perform vertical and horizontal maneuvers. In addition, the trajectory that does not leave the dense layers of the atmosphere makes it difficult to intercept. And in a critical situation, Russian generals can return to the idea of ​​global missiles. And this is not a complete list of countermeasures to avoid intercepting missiles at the active stage. When the X-90 hypersonic warhead separates from the missile, it is practically invulnerable.

This is the pride of the Russian Air Force - the Tu-160 strategic bomber worth billions of rubles. Due to its slim, elegant form, it is affectionately called the “White Swan”. However, its other names more closely correspond to reality - “Sword with 12 blades” (due to 12 cruise missiles on board), “Weapon of the Nation”, “Restraining Factor”. It is also called the “Russian flying wonder”, and NATO stands for Blackjack. The first rocket carrier was built in 1981 year. Initially, 100 of such vehicles had to be put into operation, but since the Americans insisted on including this class of bombers in the START treaty, the USSR limited itself to 33 units.

After the collapse of the Soviet Union, the Tu-160 were divided between the former Soviet republics. Currently, Russian long-range bomber aviation has 14 bombers of this class. They were originally 15, but one of them crashed over the Volga in 2003 year. Each car has its own name, for example, “Ilya Muromets” or “Mikhail Gromov”. The last of this list, “Alexander the Younger,” became operational in 2000. All of them are based in Engels on the Volga. For armament X-90 aircraft plane were increased. This modification is called Tu-160M.

    A brief reference on hypersonic missiles and RAKS -

    I was surprised in the article why the information is dated only until the 2004 of the year, and then no dates? It was a strange reading experience, as if all the yellow newspaper ducks had been gathered together. Especially in the joint development of the Ajax theme with the Chinese, one does not believe at all.

              Indeed, many lives, lives and families have been ruined. Failure for 20 years, I believe that it is time to call something else. Failure involves falling and rising. And today there is no one to rise. There is hope for the children of patriots who will be able to rationally use the achievements of their fathers in the modern world built on exclusively commodity-money relations.

    Already, no one denies that Misha Wallet, he is Misha Marked, aka Mishka Humpbacked took bribes in foreign currency. The funniest case was in South Korea, when he was put in his pocket with a bunch of witnesses. He was even given an official bribe - the Nobel Prize.
    For these bribes, OUR country:
    divided into provinces
    ditched its high-tech developments and enterprises (for some US developments, despite the sold Soviet legacy, it was only just beginning to approach)
    lost loyal allies (East Germany, Cuba, Vietnam)
    lost influence in the world
    ditched their own population
    Fortunately, now the "restoration" has begun, but the people managed to reformat (the majority) and it will take not 10 years during which, despite the losses, they were able to restore pre-war production after the Second World War, but much more.

    Denies does not deny little sense. Here if they would have put him (even if not at stake) and confiscated all the silver pieces, it would not have been different to the others. And so the train from the deputy and above is untouchable.

    MHD generator, braking flow to the optimum speed, acts as a compressor
    As far as I know, the MHD generator deionizes the plasma stream by depositing charged plasma particles in a transverse magnetic field on electrodes of the corresponding potential, as a result of which it generates electricity. And where is the compression? Thus, if the plasma flow is deposited on the electrodes, then the remaining non-ionized flow molecules will not interact with the magnetic field. In general, the development of MHD generators in the USSR rested in electrical insulation materials in connection with electrical breakdowns between the electrodes. It is incomprehensible, it was a sabotage of Jewish scholars preparing to leave in the late 80s, just sloppiness or really a technical problem.

    On the one hand, a veil of secrecy for development, on the other, an agreement with China on joint research. A clear contradiction, suggesting that this is all from the realm of utopia.
    For example, according to the instructions, the MiG-31 can fly at a maximum speed of 3M for no more than 10 minutes, otherwise the pilot's glass will become cloudy from overheating.

    It is interesting how a word thrown on the Internet begins to live an independent life.
    The fact is that most of this material (from the words "In February 2004, during a command post exercise exercise ..." to the end) is a translation of an article by Gerhard Kowalski from the German magazine "Flieger Revue" 9/2004. I did this translation for the then popular website (I won't find it in the new version of the website). Then it was published with an indication of the author and source. And then off we go. Material and pictures from it began to wander from site to site without any links.
