Fifth generation Japanese stealth: soon in the skies of the planet

History the future "Japanese breakthrough" began back in 1994, when the Institute of Technical Research and Development of the Japanese National Defense Directorate TRDI (Technical Research & Development Institute) and Mitsubishi Heavy Industries (MHI) launched the TD-X (Technology Demonstrator eXperimental) project. Experimental technology demonstrator "). The topic began to develop with the aim of creating a flying machine to replace the F-15J at the beginning of the XXI century and about 1 billion dollars were provided for this. In 1995, Ishikawajima-Harima Heavy Industries (IHI) was attracted to work on an engine with a thrust of 5000 kgf, which offered to take the F3-30 turbojet engine as a base. It was envisaged to develop on its basis a by-pass engine with an afterburner XF3-400, but received only 3500 kgf. As a result, the required 5000 kgf was achieved only by 2008 on the XF5-1 model.

Initially it was supposed to lift the plane into the air in the 2000 year, then this term was pushed back to the 2007 year, and then it was renamed ATD-X, adding Advanced (prospective). In many respects, the postponement is associated with the Mitsubishi F-2 project, which is an enlarged “American” F-16 with a large area and wingspan. By the way, the F-2 was the first in the world fighter with the AFAR locator of its own Japanese design - J / APG-1. The Japanese worked together with Lockheed Martin and by the beginning of 2016, they were able to put such machines into 64. So, ATD-X was supposed to change the F-2 in the ranks of the self-defense forces of Japan somewhere in the 2027 area of ​​the year. Resentment at the United States for refusing to share technology, and its own pride, gave the Japanese an excuse to call the project another word - Shinshin or "the spirit of the nation." In 2000, the first aerobatic display stand appeared to simulate new air combat concepts, and since 2002, the Japanese are working on a self-restoring adaptive aircraft control system. The system is called SRFCC (Self Repairing Flight Control Capability) and provides controllability of the aircraft for combat damage or malfunctions. Control signals are transmitted via a noise-resistant fiber-optic channel - fly-by-light technology.

The effective dispersion surface of the new fighter had to be measured in France at the SOLANGE test site in Bruz - the Japanese have no such conditions. For this, the 1: 1,33 model was made and, in complete secrecy, in September-November, the 2005 of the year was “run in” on a French test bench. But the aerodynamics of the future fifth-generation fighter have already been investigated in Japan at the Hokkaido test site on a radio-controlled model of the 1 scale: 5. But in 2008, a crisis broke out and the Japanese Ministry of Defense cut the budget for ATD-X right 7 times, which could not but affect the pace of development of the machine. And only the following year, the money came in an acceptable amount and this allowed the construction of the first demonstration aircraft to begin. The contract for its construction was signed at the end of 2011 of the year. They decided to assemble the car with the entire Japanese world - the fuselage and final assembly lay on the mentioned MHI, Fuji Heavy Industries was in charge of the wing consoles, and Kawasaki Heavy Industries was entrusted with the cockpit. The final specimen is 14,2 m long, its wingspan is 9,1 m and its height from the landing gear is 4,5 m. The empty Shinshin weighs from 9000 to 9700 kg (the data differs), and at maximum, 13000 kg.

It is argued that the proportion of composites in the design can reach 30%. The first car without the radio-absorbing cover of the hull so far - only the cockpit canopy has it. But the military leadership of the Japanese Ministry of Defense claims that stealth technology for the Land of the Rising Sun is quite capable of and ATD-X will (attention!) Have an EPR "less than that of a bird, but more than that of an insect." The aircraft has two engines of the mentioned type XF5-1 with the 5000 afterburner kgs with a three-stage low pressure compressor, a six-stage high pressure and two low and high pressure turbines. The thrust vector of the engine is deflected by three planes behind the nozzles of each XF5-1. The ceremonial "first riveting" of the fuselage frame was conducted at the MHI plant in Tobishim 28 in March 2012, in the presence of representatives of the Ministry of Defense and TRDI managers. Two years later, the plane in a bright red and white livery with a tail number 51-0001 left the MHI shop in Komaki, in Aichi Prefecture. At the very beginning of 2015, problems with the engine management software started and the first flight was shifted by almost 12 months. However, this deadline was not met - 28 January 2016, the plane was only officially presented to the press (then it was given the name X-2), taxiing and jogging began in February 2. The first acceleration to the speed of separation from the band took place on April 12.

On 8.47 in the morning of 22 on April 2016, a test pilot, whose name was not made public, lifted into the air from the runway of the airfield in Nagoya an experimental fifth-generation fighter X-2. As usual in such cases, the flight took place at the “minimum settings” with the chassis released at 370 km / h and without thrust control of the engines. Home plane after takeoff did not return, and after 26 minutes landed at the Japan Self-Defense Air Force Base in Gifu. Nothing unusual happened during the flight, only a few observers noted a very short X-2 run.

The future of the Shinshin X-2 Japanese leadership connects with several key aspects. The first - the formation of EPR, less than that of similar enemy aircraft. In this connection, the Japanese are actively working on new radio absorbing materials and new air intakes. The second is the development of the next-generation radar capable of detecting a subtle object. The third aspect is the principle of cloud-shooting or “cloud shooting”, which allows strikes based on external target designation sources (AWACS or other fighters). The fourth is the development of a new engine with smaller dimensions and the ability to fly to supersonic cruise mode, which X-2 is not able to do yet.

The first and so far the only flight Shinshin. Source:

According to available information, the engine, radar and stealth technology is now in the process of development and should be ready for 2020 year. Until the end of 2018, the Japanese will reflect on the development of a new fighter based on the Shinshin under the symbol F-3, and the first flights of this prototype are planned for 2024-2025. In the most optimistic version, the fifth generation car should go to the 2027 year, however, given the “quickness” of the Japanese in this matter, it is hard to believe. As an option, the Japanese can by that time cooperate with the Americans (read Lockheed Martin) in creating a joint plane with their own developments. Will Japan be able to arm themselves with their own new fighters by the time the “friends” in the district are already equipped with fifth-generation vehicles? Or, given the recent leadership doubts about the feasibility of the ATD-X project, will they remain technologically dependent on the United States?

    That's what, and in preserving their military strategic technologies, the Americans have no equal, unlike Russia .. Even Israel and Britain are not trusted, not to mention the satellite Japan. And they are doing the right thing.

      Only the Chinese insolently steal everything from all countries. If they cannot steal, they buy companies or by all means try to become partners.
      And they put it on everyone.

    He is even smaller than the F-35, how much can he take fuel and missiles? Accordingly, what is his range and combat capabilities. It seems that the Japanese without the "American umbrella" while not thinking their defense

      It is even smaller than the F-35

      So the japans themselves are not very big. And their territory is not very large. Yes, and 2 engines of 5000 kgf, this is exactly 13 tons. A F-22/35 and Su-57 more than 30 tons of take-off weight.

    It is clear that the conceptual idea embedded in modern aircraft engines has reached the limit. This is not noted only by a non-specialist. However, no one has the idea of ​​a new fundamental concept. Therefore, any new model is immediately obvious in its shortcomings. The new concept is completely based on the fundamental decisions of physicists in modeling the interaction of the body in highly dynamic contact with the flight environment. In this case, it is extremely important to re-examine the system of interaction of magnetic fluxes in an elementary dipole.

      That is, as I understand it at this stage, a dead end for engines?
      And for the new solutions, so far only basic research is going on?
      And no breakthrough decisions can be expected in the next 10-15 years?
      I understand it or not?
      1. gridasov
        gridasov 25 June 2018 18: 13
        WHY 10-15 years. A hundred years or more. And this despite the fact that the growth rate of innovative solutions is taken into account. The question, after all, is that in order to move to a new level of development of aviation flight technologies and, accordingly, engine building, several fundamental problems must be solved, which can then be systematically solved. And if such tasks are even solved by random inventions, then build a system of their relationship and adopt the methodology, then completely new methods of analysis of complex high-potential processes are needed. That is, it's math. Therefore, we will say so very simply that Fermat's theorem goes beyond the scope of the solution when using the function of a variable value of a number. When using the constant number function, a task as a search for numbers and numerical sequences is considered as an aggregate system of algorithmic constructions, but not as a search for simply numbers corresponding to the problem as theorems. That should be clear.
        If such an answer is difficult to understand, then just consider all the peak or key problems of all aircraft engines or all turbines in general and you will clearly see that the search for materials that withstand and fuels create high temperatures and pressure in the combustion chambers is a dead end. Therefore, there is only one way out - this is a search for new methods for solving the problem, which means a search for new algorithms and mathematical analysis of processes and the creation of new algorithms for processes in the engine, as a combination of not only sequential, but also related stages of processes in the engine or turbine. In my opinion, even what I said plunges people into shock. But this is an inevitable reality. You can’t tell us about the arguments that there are still prospects. Neither detonation, nor ionic, nor pulsating engines can solve the problem, since they consider only a particular solution and methodology.

          Clearly, distant fantasy at the turn of the century ...
          In the meantime, they will squeeze out everything possible and impossible from existing solutions and techniques ...

    It feels like the Americans don’t understand the countries with which they are cooperating ... Allowing them to develop the armed forces, and seeing that the Japanese just started to score on the results of the Second World War. Japan within its borders is now simply suffocating, but what will happen in 20 years?

      They do not choke. Their population is declining. Development has also slowed down.
      The standard of living is still high.

    It all depends on China. How much will the Chinese Air Force and Navy scare
    the Japanese.
    The Japanese will begin to design military equipment quickly
    only out of fear. And to allocate money for the military commissar is also only out of fear.
    Then both the "small 5th generation" - their own, and the "large 5th generation" -
    F-22 glider with F-35 filling.

    So how much time has passed since the Second World War, there are practically no participating countries left - the time for review has already come.
