However, then again, the investment in the TRJ-700 regional airliner project of Tengfei Group is indeed not small, not to mention anything else, but the aero engine tailored for this model has shrunk half of Tengfei Group's thick foundation.

Fortunately, at the critical moment, the state's special fund and CITIC Group gave strong support, coupled with the continuous blood transfusion of China Merchants Bank, which is controlled by Tengfei Group, using financial instruments, Tengfei Group was able to boil out the 6.5-ton WD-56ML turbofan engine and the 8.5-ton WD-58ML turbofan engine.

The former will be used for the basic and extended-range versions of the TRJ-700 regional airliner program.

The latter will be available on the extended version of the TRJ-700 regional airliner and other special-purpose variants.

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 airliner, but based on these two models, Tengfei Group has completed the research and development of the second-generation 6 MW core machine, and determined the overall architecture of the third-generation 11 MW core machine.

On this basis, the basic model of the third-generation aero engine of Tengfei Group, the WD-60ML large bypass ratio turbofan engine, was successfully implemented.

Since then, Tengfei Group has officially crossed the dividing line between small and medium-sized and large 10 tons in terms of aero engines, thus opening a new era.

For example, the Jianjiao 7MAX trainer \\ attack aircraft, which has been using turbojet 13 as the main power, can launch a small bypass ratio afterburner turbofan engine on the basis of the WD-60ML large bypass ratio turbofan engine after it matures, and it is expected that the cruising thrust will reach 5.6 tons, the afterburner thrust will reach 8.7 tons, and the thrust-to-weight ratio will be 7.8.

At that time, the Jianjiao 7MAX Trainer\\ attack aircraft will achieve a qualitative flight, and if it is equipped with advanced avionics systems and weapon systems, its performance is no less than that of the early third-generation fighters.

This not only enriches the product line of the Jianjiao 7MAX trainer attack aircraft and realizes the user's personalized customization, but also further relies on the platform of the Jianjiao 7MAX trainer attack aircraft to create a more modern light combat aircraft.

In addition to the Jianjiao 7MAX Trainer attack aircraft of Tengfei Group, the light fighter project of Chenggong Group and Pakistan can also be adapted to the small bypass ratio turbofan engine based on WD-60ML.

Of course, both are light combat aircraft, and there are many overlaps between the Jianjiao 7MAX high-end version and the light fighter of Chenggong Group, and future competition is inevitable.

However, whether it is Zhuang Jianye or Huang Feng, the head of Chenggong Group, is not worried.

The reason is very simple: the Jianjiao 7MAX of the Tengfei Group is mainly attacking the direction of the instructor \\ attack aircraft, taking the multi-purpose all-round route, while the light fighter of the Chenggong Group in cooperation with Pakistan is a real combat aircraft, specially born for the battlefield.

Therefore, the small bypass ratio turbofan engine developed based on WD-60ML is just right for the light fighter of Chenggong Group, and in the future, it also needs an advanced medium thrust with a thrust of 9 tons or even 10 tons and a thrust-to-weight ratio of 9 or 10 to better play its combat effectiveness.

On the other hand, Tengfei Group's Jianjiao 7MAX, there are too many tricks, the same body, but the equipment inside is completely different, the top configuration can use WD-60ML development of small bypass ratio turbofan engine, so that its performance is not inferior to the early third-generation fighter.

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

As for comfort or luxury, depending on the situation, the optional turbojet 13 or no afterburner small turbofan engine, avionics also look at the dish, whether to install advanced Doppler radar or put a counterweight iron that can talk to the tower, it depends on the user's ability, can stuff enough money, of course, use some good products;

In fact, according to different needs, Zhuang Jianye requires the design department to even choose the materials of important parts of the body.

Strive for the beggar's version of a water of aluminum alloy, the middle with a little titanium alloy, to the top with what titanium alloy, composite materials can be vigorously beckoned.

In this way, the three, six, nine and so on of the aircraft can be completely separated, so that the low price performance is more prominent, and the high price will be bought back and feel worth it from the bottom of my heart.

It's a pity that with the current technical capabilities of Tengfei Group, the personalized production of different versions is really not playable, otherwise the entire Jianjiao 7MAX will collapse, Zhuang Jianye has no choice but to give up, otherwise with Zhuang Jianye's temperament, he can definitely make an aircraft switch between the second generation aircraft and the third generation aircraft to fly.

The small bypass ratio turbofan engine is already very valuable, but it is not the most strategic in the derivative pedigree of the Ascendas Group based on the WD-60ML large bypass ratio turbofan engine.

If not, the small bypass ratio turbofan engine will not be placed in the third development sequence by Zhuang Jianye, and the derivative model that allows Tengfei Group to make every effort to tackle key problems after the WD-60ML large bypass ratio turbofan engine is a WD-62ML turbofan engine with a bypass ratio of 4.5, a two-pole high-pressure turbine and a six-stage low-pressure turbine, a twin-rotor structure, and a thrust of 9.6 tons.

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

With the WD-62ML turbofan engine less than 70% of the weight of the turbojet 8 engine, 48% of the fuel consumption, nearly 3 times the overhaul interval, with advanced aluminum-lithium alloys, advanced composite materials and other high-end aviation materials also produced by Tengfei Group.

The Northwest Aviation Plant's "God of War" series H-6 improved models will not only have a 20 percent increase in bomb load compared with the old models, but also have a range of 7,500 kilometers and a combat radius of more than 3,500 kilometers.

If it is a first-generation long-range cruise missile with a range of 1,000 kilometers and an all-composite projectile, a small laser gyroscope, and a WD-16 small turbofan engine provided by the Tengfei Group, and developed and assembled by the aerospace department, the H-6 improved model will have extremely strong long-range strike capability outside the defense zone.

At that time, in the event of the big incident more than half a year ago, the headquarters will not be helpless because there are no hole cards.

Because of this, after learning that Tengfei Group had successfully completed the commissioning of the second-generation 6 MW core engine and successfully developed the WD-60ML large bypass ratio turbofan engine on this basis, the headquarters issued an index task to Tengfei Group, instructing Tengfei Group to develop a turbofan engine with a bypass ratio of about 4 and thrust no less than that of turbojet 8 at the turn of the century for an improved model of the H-6 bomber.

In this regard, Zhuang Jianye is naturally going 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 Tengfei Group is also holding its breath because of the big incident more than half a year ago.

If the technology is advanced, it will show off its might?

Cut~~ Do you know what asymmetry is?
