Take Off My Aviation Era

Lin Guanghua's words are really right. As early as the end of the 1980s, Ascendas Group had begun to track the relevant foundations of foreign aero-engine full-power digital electronic control systems.

And at the very beginning, Ascendas Group did not think about taking the lead on its own, but placed its hopes on international cooperation.

This is not that Ascendas Group does not want to be independent, but that the stalls that Ascendas Group spread out at that time are too large, and resources in all aspects are a bit tight, and there is no energy to invest more in the full-power digital electronic control system. The control system takes the form of international cooperation, which is a quick measure to fill the gap.

So Zhuang Jianye found GM and Pratt & Whitney through McDonnell Douglas, which had a good cooperative relationship with Ascendas Group at the time, and hoped to cooperate in the digital electronic control system of aero engine.

As a result, GM and Pratt & Whitney looked at the cooperation letter of intent handed over by Ascendas Group. They did not immediately reject it. Instead, they threw a detailed introduction book of similar products to the two aviation giants of Ascendas Group, and told Ascendas Group bluntly: "You Don’t make the most popular aero engines and gas turbines. Take a look at our products. They are much better than yours. How about? Let’s do OEM for my brothers with peace of mind. Follow your eldest brother and make sure you drink wine every day. , Xiao Huazi smoking, big gold chain, small watch, and little ladies as quilted jackets!"

Zhuang Jianye is ready to cooperate. Under this premise, if he can undertake some GM and Pratt & Whitney's aero engine parts OEM, and earn some pocket money, he will naturally not mind. The problem is that GM and Pratt & Whitney directly treat Ascendas Group as a younger brother. , I wanted to get into the club without saying anything and began to cruelly oppress.

How can Zhuang Jianye stand it? Of course, he must be clear about his attitude.

GM and Pratt & Whitney originally thought that Ascendas Group had come to worship the dock, and it was naturally polite to be a younger brother. It turned out that the Ascendas Group was not a member of the club, but was planning to steal the teacher and learn the arts. If this gives a good face, what should the two elder brothers' other younger brothers think?

What's more, the full power digital electronic control system is simple, but it is actually another black technology that GM and Pratt & Whitney have accidentally led the world in the core materials of aero engines.

It is of vital significance for them to widen the gap between these two global aero-engines and other countries and maintain their leading advantages in aero-engines in the next two decades.

In fact it is true.

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

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

Others don't need to be considered, just reducing the weight of the aero engine itself makes the full power digital electronic control system immediately synonymous with the real fragrance.

What's more, the maintainability of the full power digital electronic control system is much stronger than that of the traditional hydraulic mechanical control system.

There is no way that the mechanical structure is inherently complicated, and it also serves the existence of an aero-engine, and its own coffee position is naturally an uncle. Therefore, the required accuracy and maintenance frequency can directly make the ground crew cry.

The full-power digital electronic control system is different. A master electronic controller is not only exquisite, but also can check the internal nodes through an external computer. The specially designed control software has fault prediction and autonomous detection functions. In many cases, the ground crew is not required to intervene in the inspection, and the full-power digital electronic control system itself has already displayed the faulty location.

The ground handling can be adjusted or repaired according to the displayed position, which can be described as the key, efficient and fast.

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

Due to the complicated mechanical structure of the traditional hydraulic mechanical control system, the pilot always has an inevitable lag when controlling the engine output.

As a result, when the plane is driving, it always gives people a sense of powerlessness.

It's like a car with a very trash gearbox. The sense of frustration when changing gears can give you the same sense of sight of a tractor, which can drive old drivers crazy.

The civil aviation airliner is okay. It doesn't matter if it lags behind. Anyway, you don't need to make difficult maneuvers, as long as you fly to the destination smoothly according to the route.

The fighter jets used in air combat are about to die.

You must know that air combat is changing rapidly, and with a slight delay, it may be locked by the enemy and shot into the soul.

Because of this, the combat effectiveness of a full-power digital electronic control system is very different from that of an unused fighter, because the full-power digital electronic control system can be seamlessly connected to the fly-by-wire flight control system of the aircraft, thereby optimizing the overall aircraft engine to the entire aircraft. The performance output of the fighter.

In this way, the pilot only needs to move the joystick, and everything on the aircraft will be processed efficiently and automatically.

In contrast to the traditional hydraulic-mechanical control system, the pilot is a throttle, a valve, a regulator, and a joystick...

After a set of actions, the flight attitude may not be adjusted, but the pilot is already frantic and exhausted.

The most typical is the Su-30MKI multi-role fighter that New Delhi imported from Russia. On paper, this combat aircraft is equipped with the world's leading vector engine.

However, Russia is not good at the full-power digital electronic control system, and can only use traditional hydraulic and mechanical structures to control complex structures such as vector nozzles.

This led to a sharp increase in the structural weight of the Su-30MKI. At the same time, www.readwn.com also brought unnecessary trouble to the pilot’s control, because the New Delhi pilots flying the Su-30MKI multi-role fighter needed to hold the joystick in one hand and the other. The control valve is controlled by hand, and the hydraulic button must be activated by the way, and then the balance can be grasped according to the feeling, in order to barely achieve the deflection of the vector nozzle and the strengthening of the engine thrust.

The F-22, which also uses the vector engine, is seamlessly connected to the aircraft’s fly-by-wire control system due to the engine’s full-power digital electronic control system, so that pilots driving the F-22 want to achieve the deflection of the vector nozzle and directly pull the joystick. Achieve perfect violence output.

With such a big performance advantage, how could GM and Pratt & Whitney cooperate with each other? Of course, it is worthwhile to cover up and engage in monopoly.

To be honest, at that time, when GM and Pratt & Whitney had a company that could tell Ascendas Group: "Young man, it's not easy, okay, big brother will help you."

Zhuang Jianye can take the Ascendas Group to pay his respects.

As a result, no one waited to see the Ascendas Group. Either he was a little brother and fell away, or he was abandoned as a stinky shit. Zhuang Jianye unfortunately chose the third road. Isn’t it just a quagmire? Well, let’s be the big brother. !
