Chapter 924

But then again, the investment in the trj-700 regional airliner project of Tengfei group is not small, let alone anything else, but the aero-engine tailored for this model has reduced the solid foundation of Tengfei group by half.

Fortunately, at the critical moment, the state's special fund and CITIC Group have given strong support, and China Merchants Bank, which is controlled by Tengfei group, has used financial tools to continuously transfuse blood. Tengfei group has only managed to survive 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 types of trj-700 regional airliner project.

The latter will be equipped to the extended version of trj-700 regional airliner project and other special purpose derivative models.

However, no matter wd-56ml or wd-58ml, the significance of these two aeroengines 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 of 6 MW core aircraft and determined the overall architecture of the third generation of 11 MW core aircraft.

On this basis, the wd-60ml turbofan engine, the basic model of the third generation aeroengine of Tengfei group, was successfully launched.

Since then, Tengfei group has officially crossed the dividing line between small and medium-sized enterprises and large-sized enterprises in terms of aero-engine, thus opening a new era.

For example, after the wd-60ml turbofan engine with large bypass ratio matures, the j-jiao 7max trainer attack aircraft, which has been using turbojet 13 as its main power, can launch the afterburner turbofan engine with small bypass ratio on its basis. It is estimated that the cruise 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 j-jiao-7max trainer attacker will achieve qualitative overflight. If equipped with advanced avionics system and weapon system, its performance will be no less than that of the early third generation fighter.

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

In addition to Tengfei group's j-jiao 7max trainer attack aircraft, the light fighter project of Chenggong group cooperating with Pakistan can also adapt to the improved small bypass ratio turbofan engine based on wd-60ml.

Of course, both of them are light combat aircraft. There are many overlaps between the high configuration version of j-jiao 7max and the light fighter of Chenggong group, so the competition in the future is inevitable.

However, neither Zhuang Jianye nor Huang Feng, the leader of Chenggong group, are worried.

The reason is very simple: Tengfei group's j-jiao 7max focuses on the direction of the trainer attack aircraft, which is a multi-purpose all-round route; while the light fighter aircraft cooperated by Chenggong group and Pakistan is a real combat aircraft, which is 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 Chenggong group. In the future, the advanced intermediate thruster with thrust of 9 tons or even 10 tons and thrust weight ratio of 9 or 10 will be needed to give better play to its combat effectiveness.

On the other hand, the j-jiao 7max of Tengfei group has too many patterns. The same airframe has completely different equipment. It is equipped with a small bypass ratio turbofan engine developed by wd-60ml, making its performance no less than that of the early third generation fighters.

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

As for the comfort or luxury model, choose turbojet 13 or small turbofan engine without afterburner according to the situation. Avionics also watch dishes. It depends on the user's ability to install advanced Doppler radar or put a counterweight iron block that can communicate with the tower. If you can plug enough money, you can use some good products. If you can't, don't be picky. You can fly into the sky Just come down.

Of course, if Tengfei group does this, some people will say that it's too bad. That's too much to look down on Zhuang Jianye's mind. In fact, according to different needs, Zhuang Jianye requires the design department to choose different materials for important parts of the body.

For beggars version of a water of aluminum alloy; with a little bit of titanium alloy; to the top with what titanium alloy, composite materials can be vigorously up.

Only in this way can we completely separate the three, six and nine grades of the aircraft, make the low price performance more prominent, and the high price will be worth it from the bottom of my heart.

Unfortunately, with the current technical ability of Tengfei group, the personalized production of different versions can't be played. Otherwise, the whole Jian Jiao 7max will collapse, and Zhuang Jianye has no choice but to give up. Otherwise, with Zhuang Jianye's temperament, an aircraft can definitely switch from the second generation to the third generation.

Small bypass ratio turbofan engine is very valuable, but it is not the most strategic one in the derivative pedigree of Tengfei group based on 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 of wd-62ml turbofan engine with bypass ratio of 4.5, bipolar high pressure turbine and six stage low pressure turbine, double rotor structure and thrust of 9.6 tons, which let Tengfei group make full efforts to tackle key problems after wd-60ml large bypass ratio turbofan engine.After mass production, this turbofan engine will replace the turbojet 8 engine and become the new heart of the "ares" series, the latest improved model of Northwest Airlines' H-6 bomber.

Compared with turbojet 8 engine, wd-62ml turbofan engine has less than 70% weight, 48% fuel consumption and nearly three times overhaul interval. It is also equipped with advanced aluminum lithium alloy, advanced composite materials and other high-end aviation materials produced by Tengfei group.

The improved "ares" series H-6 of Northwest Airlines will not only increase the missile load by 20% compared with the old models, but also reach a range of 7500km and a combat radius of more than 3500 km.

If the first generation long-range cruise missile with a range of 1000 km is developed and manufactured by the Aerospace Department in cooperation with the all composite missile body, small laser gyroscope and wd-16 small turbofan engine provided by Tengfei group, the improved H-6 will have a very strong long-range strike capability outside the defense area.

At that time, in the face of the big event more than half a year ago, the headquarters will not be at a loss because they have no cards.

Because of this, after learning that Tengfei group has successfully completed the commissioning of the second generation of 6 MW core machine, and on this basis has successfully developed wd-60ml turbofan engine with large bypass ratio, the headquarters issued a target assignment to Tengfei group, and instructed Tengfei group to develop a turbofan engine with bypass ratio of about 4 and thrust no less than turbojet 8 at the turn of the century, which is used for the boom-6 boom The improved model of blaster.

In this regard, Zhuang Jianye naturally goes all out. This is not only a matter of money, but also a matter of dignity. You should know that the whole Tengfei group, including Zhuang Jianye, is also choked by the big event more than half a year ago.

How can we show off our power with advanced technology?

Do you know what is asymmetric?
