Chapter 924 The Heart of the God of War: WD-62ML Turbofan Engine

Previous page        Return to Catalog        Next page

    But then again, Ascendas Group¡¯s investment in the trj-700 regional passenger jet project is indeed not small. If nothing else, the aviation engine tailor-made for this model has shrunk Ascendas Group¡¯s solid financial resources.  Half of it.

    Fortunately, the country's special fund and CITIC Group provided strong support at the critical moment, and China Merchants Bank, controlled by Ascendas Group, continued to use financial instruments to inject blood. Only then did Ascendas Group put the 6.5-ton WD-56ml turbofan engine and the 8.5-ton class  The wd-58ml turbofan engine has survived.

    The former will be used for the basic type and extended range type of the trj-700 regional passenger aircraft project.

    The latter will be equipped on the extended version of the trj-700 regional passenger aircraft project and other derivative models with special purposes.

    However, whether it is wd-56ml or wd-58ml, the significance of these two aero engines is not to solve the power problem of trj-700 regional passenger aircraft, but based on these two models, Ascendas Group has completed the second-generation 6-megabyte  watt core machine research and development, and determined the overall architecture of the third generation 11 MW core machine.

    Based on this, Ascendas Group¡¯s third-generation aeroengine basic model, the wd-60ml large bypass ratio turbofan engine, was successfully launched.

    Since then, Ascendas Group has officially crossed the 10-ton dividing line between small and medium-sized and large-sized aircraft engines, thus opening a new era.

    For example, the JJ-7MAX trainer attack aircraft, which has been using the turbojet 13 as its main power, can launch a small bypass ratio afterburning turbofan engine based on the wd-60ml large bypass ratio turbofan engine after it matures.  It is expected that the cruise thrust will reach 5.6 tons, the afterburner thrust will be 8.7 tons, and the thrust-to-weight ratio will be 7.8.

    By then, the JJ-7MAX trainer attack aircraft will achieve qualitative flight. If equipped with advanced avionics systems and weapon systems, its performance will be no less than that of early third-generation fighter jets.

    This not only enriches the product line of the JJ-7MAX trainer attack aircraft and enables users to customize it, but also allows us to further rely on the JJ-7MAX trainer attack aircraft platform to create a more modern light combat aircraft.

    In addition to the Ascendas Group¡¯s J-7MAX trainer attack aircraft, the light fighter project jointly developed by the Chengdu Group and Pakistan can also be adapted to a small bypass ratio turbofan engine based on the improvement of wd-60ml.

    Of course, as both are light combat aircraft, the high-end version of the JJ 7max has many overlaps with the light fighters of the Chengdu Group, and competition in the future is inevitable.

    But neither Zhuang Jianye nor Huang Feng, the head of Chenggong Group, are worried.

    The reason is very simple. Ascendas Group¡¯s JJ-7MAX is mainly designed as a training attack aircraft, taking a multi-purpose all-round route; while the light fighter aircraft cooperated by Chengdu Group and Pakistan are real combat aircraft, specially designed for the battlefield.

    Therefore, the small bypass ratio turbofan engine developed based on wd-60ml is just right for the light fighter of the Chenggong Group. In the future, it will need an advanced mid-range thruster with a thrust of 9 tons or even 10 tons and a thrust-to-weight ratio of 9 or 10.  Good combat effectiveness.

    On the other hand, the Ascendas Group's JJ 7max has too many tricks. The same body, but the equipment inside is completely different. The top version can use the small bypass ratio turbofan engine developed by WD-60ml, making its performance no less than  In the early third generation fighter aircraft.

    The beggar version may only use a turbojet 7 engine used in the early days of the J-7. The internal control system and avionics system are completely copied from the J-7's architecture.

    As for comfort or luxury, you can choose a turbojet 13 or a small turbofan engine without afterburner depending on the situation. The avionics also depends on the dish, whether to install an advanced Doppler radar or a counterweight that can communicate with the tower.  As for iron blocks, it depends on the user's ability. If you can stuff enough money, of course you should use some good products; if it's almost interesting, don't be picky. Just be able to fly into the sky without falling down.

    Of course, if Ascendas Group did this, some people would say it was a scam, and that would underestimate Zhuang Jianye¡¯s mind. In fact, according to different needs, Zhuang Jianye asked the design department to choose different materials for important parts of the aircraft body.

    ?? Strive for the beggar¡¯s version of aluminum alloy; the middle version is slightly more titanium alloy; when it comes to the top version, what kind of titanium alloy and composite materials can be used to say hello.

    In this way, we can completely separate the three, six, and nine grades of the aircraft, making the low-priced one more cost-effective, and you will feel it is worth it if you buy it back at a high-priced one.

    It's a pity that with the current technical capabilities of Ascendas Group, the personalized production of different versions is really impossible. Otherwise, the entire JJ 7max will collapse. Zhuang Jianye gave up helplessly. Otherwise, with Zhuang Jianye's temperament, he would definitely be able to make a  The aircraft switches between second-generation and third-generation aircraft to take off.

    The small bypass ratio turbofan engine is already very valuable, but among Ascendas Group¡¯s derivative pedigree based on the wd-60ml large bypass ratio turbofan engine, it is not the most strategically significant.

    If this is not the case, small bypass ratio turbofan engines will alsoIt will be placed in the third development sequence by Zhuang Jianye, and the derivative model that allows Ascendas Group to work hard on the wd-60ml large bypass ratio turbofan engine is a bypass ratio of 4.5, with a two-pole high-pressure turbine and a six-stage low-pressure  Turbine, dual-rotor structure, wd-62ml turbofan engine with a thrust of 9.6 tons.

    After mass production, this turbofan engine will replace the turbojet 8 engine and become the latest improved model of Northwest Aviation Factory's H-6 bomber, the new heart of the "God of War" series.

    Compared with the turbojet 8 engine, the wd-62ml turbofan engine has less than 70% weight; 48% fuel consumption; nearly 3 times the overhaul interval, combined with advanced aluminum-lithium alloy and advanced composite materials also produced by Ascendas Group  Materials and other high-end aviation materials.

    Northwest Aviation Factory¡¯s ¡°God of War¡± series of H-6 improved models will not only have a 20% increase in bomb load compared to the old model, but also have a range of 7,500 kilometers and a combat radius of more than 3,500 kilometers.

    If combined with the all-composite missile body, small laser gyroscope and wd-16 small turbofan engine provided by Ascendas Group, and developed and assembled by the aerospace department, the first-generation long-range cruise missile with a range of 1,000 kilometers,  The improved version of the H-6 will have extremely strong long-range strike capabilities outside the defense zone.

    By then, when faced with the big event that happened more than half a year ago, the headquarters will not be helpless because it has no trump card.

    Because of this, after learning that Ascendas Group successfully completed the production of the second-generation 6-megawatt core engine and successfully developed the wd-60ml large bypass ratio turbofan engine, the headquarters issued an indicator to Ascendas Group  The mission statement instructs Ascendas Group to develop a turbofan engine with a bypass ratio of about 4 and a thrust no less than that of the turbojet 8 at the turn of the century, for use in an improved model of the H-6 bomber.

    In this regard, Zhuang Jianye naturally went all out. This is not only a matter of money, but also a matter of dignity. You must know that including Zhuang Jianye, the entire Ascendas Group is also holding its breath because of the big incident more than half a year ago.
