Lin Guanghua is really right, as early as the end of the eighties, Tengfei Group has begun to track the relevant basis of the full digital electronic control system of foreign aero engines.

And at the very beginning, Tengfei Group did not think about taking the lead by itself, but pinned its hopes on international cooperation.

It's not that Tengfei Group doesn't want to be independent, but that Tengfei Group was too big at that time, and all aspects of resources were a little tight, and there was no energy to invest more in the full digital electronic control system.

Therefore, Zhuang Jianye found GM and Pratt & Whitney through American cooperative manufacturers such as McDonnell Douglas, which had a good cooperative relationship with Tengfei Group at that time, and hoped to cooperate in the aero-engine full digital electronic control system.

As a result, GM and Pratt & Whitney looked at the letter of intent for cooperation handed over by Tengfei Group, and did not immediately refuse, but threw a detailed introduction to the similar products of the two aviation giants of Tengfei Group, and bluntly told Tengfei Group: "Don't build your aero engines and gas turbines, look at our products, they are much better than yours, how about it?"

Zhuang Jianye is ready to cooperate, if under this premise, to undertake a part of GM and Pratt & Whitney's aero engine parts OEM, to earn a little pocket money naturally will not mind, the problem is that GM and Pratt & Whitney directly take Tengfei Group as a little brother, and want to enter the community without saying anything and start ruthlessly squeezing.

Where can this Zhuang Jianye stand it, of course, he has to make his attitude clear.

GM and Pratt & Whitney originally thought that Tengfei Group was coming to worship the dock and be a little brother, which was naturally polite. It turned out that Tengfei Group did not join the club, but was ready to steal teachers to learn art, if this is a good face, what should the other younger brothers under the two eldest brothers think?

What's more, the plenipotentiary digital electronic control system is simple, but in fact it is another world-leading black technology of General Motors and Pratt & Whitney in the core materials of aero engines.

It is of vital significance for them, the two global aero engine leaders, to widen the gap with other countries and maintain the leading edge in aero engines in the next two decades.

In fact, it is.

Unlike the traditional hydraulic mechanical control system, which requires a set of complex mechanical components and structural accessories, which are installed on the underside or side of the aero engine, the full-power digital electronic control system only needs a core electronic control box, and can control the turbine temperature, turbine speed, fuel injection rate and fan arithmetic of the aero engine with the precision servo control mechanism and sensors integrated with the aero engine.

One is a large and complex mechanical attachment that occupies almost half of the body of an aero engine, and the other is an electronic control box the size of a computer screen.

Regardless of other considerations, the weight reduction of the aero engine itself alone makes the full-power digital electronic control system immediately synonymous with true fragrance.

What's more, the full-powered digital electronic control system is also much stronger in maintainability than the traditional hydraulic mechanical control system.

There is no way that the mechanical structure is already complex, and it is an uncle-level existence that serves aero engines, and its own coffee position is naturally also an uncle, so the required accuracy and maintenance frequency can directly make the ground engineer collapse to cry.

The full digital electronic control system is different, a master control electronic controller, not only exquisite, but also through the external computer can be checked on the internal nodes, and the specially designed control software has more fault prediction and autonomous detection functions, so that in many cases, the ground staff do not intervene in the inspection, the full authority digital electronic control system itself has been displayed the fault location.

The ground crew can be adjusted or repaired according to the displayed position, which can be said to be to the point, efficient and fast.

Of course, this is only one aspect of the many benefits of the full digital electronic control system, and what really makes this technology a treasure for American aviation giants is the qualitative improvement of flight quality by the full digital electronic control system.

Due to the complex mechanical structure of the traditional hydromechanical control system, the pilot always has an unavoidable lag when controlling the engine output.

So much so that when flying an airplane, it always gives people a sense of powerlessness that is unresponsive.

It's like a car with a very rubbish gearbox, and the frustration of changing gears can pause out the sense of sight of a tractor, which can make the old driver crazy.

Civil airliners are okay, it doesn't matter if they lag behind, anyway, they don't need to do a difficult maneuver, as long as they fly smoothly to the destination according to the route.

Fighters for air combat are about to die.

You must know that air combat is ever-changing, and if you delay it a little, you may be locked by the enemy and hit the soul with one shot.

Because of this, the combat effectiveness of a fighter jet with full authority digital electronic control system is very different from that of a fighter jet that is not used, because the full authority digital electronic control system can be seamlessly connected to the aircraft's fly-by-wire flight control system, thereby optimizing the performance output of the aero engine to the entire fighter aircraft as a whole.

In this way, the pilot only needs to move the joystick, and everything on the plane is handled efficiently and automatically.

In contrast, in the traditional hydromechanical control system, the pilot is the throttle, the valve, the regulator, and the joystick......

After a set of movements, the flight attitude may not have been adjusted, but the pilot is already tired and half dead.

The most typical is the Su-30MKI multi-role fighter imported from Russia by New Delhi, which on paper is equipped with a world-leading vector engine.

However, Russia is not good at full digital electronic control systems, and can only use traditional hydromechanical structures to control complex structures such as vector nozzles.

This led to a surge in the weight of the Su-30MKI structure, but also brought unnecessary trouble to the pilot's control, because the New Delhi pilots flying the Su-30MKI multi-role fighter need to hold the control stick in one hand, control the control valve with the other hand, and activate the hydraulic button by the way, and then grasp the balance according to the feeling, in order to barely achieve the deflection of the vector nozzle and the strengthening of engine thrust.

The F-22, which also uses a vector engine, has a seamless connection between the engine's full-powered digital electronic control system and the aircraft's fly-by-wire control system, so that the pilot pilots of the F-22 want to achieve the deflection of the vector nozzle and directly pull the joystick to achieve perfect violent output.

With such a big performance advantage, how can GM and Pratt & Whitney come up with it for cooperation? Of course, it is only cost-effective to cover up and engage in monopoly.

To be honest, at that time, one of the companies in General Motors and Pratt & Whitney could say to Tengfei Group: "Young man, it's not easy, okay, big brother can help you." ”

Zhuang Jianye can take Tengfei Group to worship.

As a result, no one treated Tengfei Group, and either sank as a little brother or was abandoned as a stinky shit, Zhuang Jianye unfortunately chose the third path, isn't it just a status of the rivers and lakes, or not, then be a big brother himself!
