    "Thisthisisn't this an indicator of the wd-72suv high-power military turbofan engine?"

    After listening to the words of the old commander, the person in charge of an aircraft engine factory suddenly showed a look of surprise on his face. There was no way that the index of the wd-62mvp high-power military turbofan engine mentioned by the old commander was the WD that they were competing for.  The predicted indicators of the 72suv high-power military turbofan engine are not imaginary, they are exactly the same.

    What does this mean?

    In a word, Ascendas Group completely abandoned their group of others and went it alone without any moral ethics!

    The problem is that these aircraft engine manufacturers can¡¯t say anything at all. Has it cost you aircraft engine manufacturers a penny?  Or does it matter what kind of assistance you want?

    There is nothing. They are all products made by Ascendas Group with their own money. What can you say?

    What¡¯s more, the Ascendas Group makes the WD-72suv high-power military turbofan engine?  It¡¯s not good at all!  The model number is clearly wd-62mvp. Even a primary school student knows that there is a difference of 10 numbers between 62 and 72. Can the two be the same?

    Even if the wd-62mvp is also a high-power military turbofan engine, it is essentially different from the wd-72suv high-power military turbofan engine. Even if the performance indicators are exactly the same, the essential difference between the two is inconvenient.

    It¡¯s like a monk and a bald donkey. They both refer to monks, but there is a difference between a positive word and a derogatory word!

    It was precisely because he knew the secrets behind this that the surprised person in charge of the aircraft engine factory could question it tactfully. Otherwise, he would directly scold Ascendas Group for being careless and monopolizing the model.

    The problem is that they didn¡¯t make WD-72suv, but WD-62mvp!

    As for getting the so-called explanation, the person in charge of the aircraft engine factory had no hope at all. The attitude of the old chief engineer who came all the way was well known to everyone in Sima Zhao's heart. He just said that Ascendas Group was his cover and Zhuang Jianye was his biological son.

    You asked the old manager to explain, and with his old man's temper, he replied: "Is your factory capable of making a No. 10 spare aero engine?" That would be embarrassing.

    In fact, the person in charge asked other people, including the deputy director, to warn that Ascendas Group was playing tricks on the model. Later, when he arrived at the scene, he saw Zhuang Jianye and other Ascendas Group leaders.  , everyone, don¡¯t be cowardly, we must unite no matter what, whether he is MVP or SUV, we have to let them participate before talking about it.

    How many of them are stupid people who can hold the position of the person in charge of each aircraft engine plant? Naturally, they understood the person in charge of the aircraft engine plant who made the surprise statement. However, before they could reach an agreement, the old chief engineer had no idea.  Some explained cheerfully: "This comrade said that the indicators are the same as those of the WD-72suv. Indeed, the indicator data are similar, but based on the similarity of the data, it is a bit one-sided to say that the WD-62mvp is a modified model of the WD-72suv.  Yes, the data of the Russian al-31 and the American f110-ge-129 are still similar. Can we say that the al-31 is an f110?

    The same principle applies to wd-62mvp and wd-72suv. What is wd-72suv?  It is a true high-end thrust military engine. The thrust-to-weight ratio of the initial mass-produced model is set at 8, the mid-term mature model is to reach 10, and the later development capability is to be increased to 15, thus serving as the main power for the next generation of combat aircraft.  source.

    Therefore, the wd-72suv is not an independent aeroengine, but a long-term development system. Because of this, starting from the core engine, the standards of the entire project are very high, and a third-generation core engine with a power of 25mw is required.  Only on this basis can we derive advanced aero engines that can cover the next generation of combat aircraft.  "

    He paused for a moment, then pointed to the TNB-19S aero-engine test machine that had landed on the airport runway and continued: "The WD-62mvp obviously cannot meet such a high standard. If nothing else, in terms of core aircraft, WD-  The 62mvp is half a grade worse than the wd-72suv. The wd-72suv is expected to use a third-generation core machine with a converted flow rate of 30kgs and a cycle power of 25mw. The wd-62mvp only uses the hx- which is upgraded from the second-generation core machine.  For a 25-17 core machine, the converted flow rate is 25kgs, and the cycle power is only 17mw. It can be regarded as a second-generation and semi-transitional model at best.

    A high-power engine made with such a core machine can barely be used in the production version of Project 10. The next generation of combat aircraft is simply out of reach. Otherwise, I would not be able to use this engine as a Project 10 engine.  It is a spare engine for Project No. 1. I really feel that this engine has too many limitations!

    This can be seen from the specific indicators of wd-62mvp. The diameter is 1280mm, the length is 4982mm, the engine air intake flow is 118kgs, the bypass ratio is 0.78, the fuel consumption of afterburner thrust is 1.8kgdan¡€h, and the fuel consumption of cruise without afterburner is 0.6  kgdan¡€h, the temperature in front of the turbine is 1728k, which is 1454 degrees Celsius"

    At this moment, the old teacher crossed his arms on his chest, his still thick white hair blowing in the summer breeze.??Fluttering, with that patient and kind face, he has quite the style of everyone. Instructing the wd-62mvp and wd-72suv is even more aloof like a hero. With the data of countless treasures, it really shows the style of everyone.  incisively and vividly.

    However, when these words came to the ears of the deputy director and the heads of the aircraft engine plant, they all looked at the old commander as if they were looking at monsters.

    Do you dare to say that such data has too many limitations?

    Do you have any idea about the level of domestic high-power military engines?

    The various indicators of wd-62mvp are not as simple as good. They are so good that they are about to explode. To a certain extent, wd-62mvp has surpassed the Russian-made al-31.

    Not to mention anything else, just talking about the temperature in front of the turbine, the al-31 engine is only 1666k, which is equivalent to 1392 degrees Celsius, while the wd-62mvp is 1454 degrees Celsius, which is really 62 degrees higher than the al-31 engine. This proves the potential of the wd-62mvp  It has not been fully exerted yet, and there is still a lot of room for improvement in the future.

    In addition, the fuel consumption is also crushing the al-31. After all, the actual fuel consumption of the al-31 when using afterburner thrust is 2.3kgdan¡€h, and the cruising state without afterburner is 0.8kgdan¡€h.

    It seems that the numerical difference is not big, but if the large base of several tons of fuel load in the fighter is weighted, the difference is quite considerable.

    This gap gives wd-62mvp more endurance time and longer range, which greatly improves both the consumption of close air combat and long-distance raid operations.

    Based on this, many heads of aircraft engine manufacturers no longer compare the AL-31 with the WD-62mvp, but rather with the American-made F110 aero engine, because the WD-62mvp is almost equivalent to the American-made F110 series engines, and even  There are also surpasses in some indicators.

    You must know that the F110 series aeroengine is the core power of a series of main fighters, carrier-based aircraft and bombers such as the US military's F-15, F-16, F-14, B-2, etc. It can be called a classic among the world's aviation engines.

    It is the powertrain that aviation designers around the world dream of. Now, the WD-62MVP, which is no less than the F110, is placed in front of your boss. But you said it has limitations. If the boss is not highly respected, otherwise these people can do it.  He grabbed the other person's neck and yelled: You don't like it, give it to me, I want it, I want it all!
