    No wonder these five words are so shocking. Supersonic cruise is one of the most important indicators of the next generation of combat aircraft. However, it is not easy to achieve this goal. In addition to making disruptive breakthroughs in the starting shape of the aircraft,  In addition, the most important thing is the aviation engine.

    Not only the thrust must be large, but also the duration in the afterburner thrust state must be long.

    ??In other words, this type of engine is a powerful thing that came from heaven. It must not only be powerful but also durable.

    There are currently only two ways to achieve this kind of superpower like a macho man descended from the sky. One is the traditional technology school represented by Pratt & Whitney's F-119 aero engine, which is based on new materials and new processes and uses traditional technology.  The aero-engine architecture achieves the so-called powerful miracle.

    This technical route is mature and reliable, but the overall technical potential has reached a peak and it is difficult to make breakthroughs.

    ¡°Perhaps we can still make some achievements on the next generation of combat aircraft, but on the next generation of combat aircraft, we have to face the embarrassment of having to start over.

    The other is the variable cycle system represented by the universal F-120 aero engine, which changes the engine's working mode according to different situations to achieve reliability, fuel efficiency and durability.

    This technical route not only achieves unimaginable technical performance on the next generation of combat aircraft, but is also the most feasible power solution for the next generation of combat aircraft in the future.

    It¡¯s obvious that Ascendas Group is following a general variable cycle plan. As for the goal, is there any need to say it?

    They are not only targeting the power matching of the next generation of combat aircraft, but also including the next generation of combat aircraft. Thinking of the upcoming China Takeoff, anyone with an online IQ can understand that China is  Ascendas is the leader in the domestic aerospace industry.

    Other aircraft engine factories can either join quickly and create brilliance together, or they can be marginalized directly and live or die.

    As for how to choose, is there any need to say?

    Just when Wang Erzhu and others finally saw the situation clearly and began to figure out how to best enter the new big family of China Takeoff, the staff on site once again took out the soundproof earmuffs and distributed them to everyone present.  , Wang Erzhu took it and took it with him. After a while, the wd-490x engine started at Zhuang Jianye's signal, and then Zhuang Jianye's unhurried voice came from the earmuffs:

    ¡°Our wd-490x adopts a variable circulation mode and has two built-in fan systems, namely a primary fan at the front and a secondary fan equipped with a compressor at the front of the core machine.

    In the low power state of subsonic cruise, the wd-490x engine works in double duct, that is, turbofan mode. In the second quarter, the fan will generate a pressure difference with the outer duct, and more air will enter the outer duct, thus  Increase thrust.

    In the high-power state of supersonic cruise, the engine operates in a single duct, that is, turbojet mode. At this time, a positive fan cooling airflow pressure difference is maintained between the afterburner lining and the tail nozzle lining; at the same time, the external bypass  The pressure in the channel increases until it exceeds the exhaust pressure of the second-stage fan. Under the action of back pressure, the air is forced into the core machine. A small amount of air is led out from the special channel for use in the afterburner, nozzle cooling and aircraft bleed air  ¡­¡±

    Following Zhuang Jianye's description, the on-site staff operated the wd-490x engine to test the normal cruise state and the afterburner cruise state. Looking at the realistic numbers on the screen, Wang Erzhu and others had to marvel. Ascendas Group  Its technical strength in aviation development is indeed unparalleled in the country.

    Even if China Takeoff is not established, they will inevitably take away the leadership of the domestic aerospace development industry in the future.

    Fortunately, the inner monologue of Wang Erzhu and others was not known to the aerospace department. Otherwise, the people from the aerospace department would have pointed at Wang Erzhu and others and cursed: "You are the only ones who don't know the heights of the sky."  If we hold on there, we have surrendered long ago. What is a variable cycle aero engine? It is a high-combustion turbine ramjet combination power that you have never seen in a hypersonic glider. That is the pinnacle of the power field, the black technology among black technologies.  !¡±

    Yes, relevant companies and units in the aerospace sector have already acquiesced to the establishment of China Ascendas Group on the basis of Ascendas Group. It¡¯s not that they don¡¯t want to compete like in the aviation field, the key is what Ascendas Group has come up with.  It¡¯s hard not to be convinced.

    The power system with variable cycle system is indeed the mainstream development direction in the future, but the key application area is not aeroengines, but future hypersonic weapon systems and aerospace aircraft.

    ?That is, high-combustion turbine stamping combined power.

    Nowadays, only Ascendas Group is conducting research in related fields in China and has made considerable progress. There is no way, who has allowed them to tap into the potential of anti-ship ballistic missile re-entry warheads over the years, and this re-entry warhead  It's a thing in itself??Hypersonic attack weapons.

    Once this kind of warhead is equipped with high-burning turbine ramjet combined power one day in the future, the attack power

    For this reason, the aerospace department has long turned a blind eye to China's Ascendas Group. Anyway, Ascendas Group has not been able to figure out the rocket business for a while, and it is impossible for other aerospace departments to understand it in a short time.  Gas turbine stamping combined power, in this case the two sides can be considered to be on the same page, why bother hurting each other.

    Of course, if you don't want to cause trouble yourself, you can't go with the aerospace department and don't want to watch the fun. Anyway, there are too many intersections between the aerospace department and Ascendas Group. There are always unconvinced companies and units that want to have a head-on confrontation. This is the case in the aerospace industry.  The most positive one, but now

    "Everyone, I won't say anything else. I, Zhuang Jianye, will explain everything to you today" After briefly introducing the wd-490x engine, Zhuang Jianye suddenly changed the subject: "The wd-490x engine is not perfect.  There are still a lot of places, if you guys are willing to help, then let's push this project forward together. If you feel it's not suitable, it doesn't matter, just make friends!"

    As a result, before he finished speaking, Wang Erzhuzi, like the sprinter who heard the starting gun, immediately raised his hands and shouted: "Mr. Zhuang, what you said is public. Others don't know it. Anyway, our xx factory is the first to support it.  "

    ¡°And me~~¡±

    ¡°It¡¯s the same in our factory~~~¡±

    "Mr. Zhuang, as long as you say a word, our factory will hit wherever you point"

    Before Wang Erzhu's shouts could stop, the shouts of everyone in the venue started one after another. Judging from the enthusiasm, it seemed that Zhuang Jianye was their leader, their leader. On the contrary, the deputy director standing in the corner became a man who was not embarrassed.  They are such outsiders that the people in charge of these aviation development plants don¡¯t even bother to talk to them.

    They are all people with good hands and eyes. The bosses behind each have made it clear long ago that the aviation development policy department where the deputy director is located will be integrated into the Commission of Science, Technology and Industry for National Defense and merged with the power policy department of the aerospace department into a comprehensive one.  The main responsibility of the policy research department is to study and plan the development of domestic aerospace power systems and related industry supporting policies.

    It can be regarded as a complete decoupling from the enterprise.

    Even if you don¡¯t care about money, people, or power, then who will give you a favor?

    Naturally, the tea got cold before the person left.

    Zhuang Jianye has no time to care about the turbulent world of the deputy director. What he said today is to do internal integration. Now that the hard rock in the aviation development field has been pried open, the subsequent matters will be easier to handle.

    So one month after Zhuang Jianye received the person in charge of an aircraft engine factory, the word "China" was added in front of the big characters "Tengfei Group" on the Ascendas Group headquarters building in Xingzhou. At the same time, the corporate information of the Industrial and Commercial Bureau also  Ascendas Aerospace Group Co., Ltd. from Xingzhou officially changed its name to China Ascendas Group Co., Ltd.!
