Chapter 916

If you want to be a big brother, you have to be willing to put in.

The problem is that at the end of the 1980s and the beginning of the 1990s, Tengfei group was just in a critical period of transformation, and many important projects were tightly tightened.

There is no energy to engage in full digital electronic control system.

If this is other units, it is estimated that it will be put in place. When other projects are almost completed, the funds will be collected and the full digital electronic control system will be launched.

But who is Zhuang Jianye? He is a ruthless character who is determined to go black. What's more, he wants to fight for the position of Tengfei group in the international aero-engine field and ascend the throne of big brother. Naturally, he has to seize every minute.

But what if we don't have enough resources and energy?

It's easy to do. It's not enough to put such an arduous task on the key models supported by the state.

As an advanced third generation fighter, the telex control system was determined to be used at the beginning of the 10th project.

For this reason, the mechanical and Electrical Department of Tengfei group has also become an important supporting manufacturer of servo motor for No.10 project. In order to complete the coordination between the fly by wire control system and airborne electronic system of No.10 project, Tengfei group has also spared no effort to give up its underpants and provided three "science fiction star" special aircraft for test and verification to the national flight test center.

With such a large amount of capital, the advanced combat aircraft without the full digital electronic control system of the aero-engine is just like the bubbling goddess of beauty, with two small white pimples on her face. How can we see that it is not perfect.

In fact, it is.

Due to the successive ticket skipping of domestic high thrust military aeroengine, the service of domestic engine installed in No.10 project has become a miraculous small probability event.

In order to ensure that it will be put into operation at the end of the 1990s and form combat capability at the beginning of the 21st century, the No. 10 project team has no choice but to choose the al-31 high thrust military aeroengine equipped on Su-27.

However, the thrust of this Russian made aeroengine can meet the requirements of No. 10 project, but the engine control system is not satisfactory.

Because it uses a set of hydraulic machinery analog digital aeroengine control system which was finalized by the former Soviet Union in the mid-1980s.

On the whole, it is not as complex and anti-human as the traditional hydraulic mechanical control system. Many electronic components are added to simplify the control mechanism.

But in terms of performance, compared with the full digital electronic control system, there is still a big difference.

This is like a mobile phone. If we say that it is a smart machine with advanced performance of full digital electronic control system, then the hydraulic machinery analog digital aeroengine control system adopted by the Russians is a brick like cell phone.

It can only be said that it is slightly better than the traditional hydraulic mechanical control system.

This can be seen from the Su-27's flight control system. The cool Su-27 uses a digital analog operating system, not a pure digital redundant fly by wire control system at all.

It's not that the Soviet Union didn't want to use the digital fly by wire control system at that time, but because the control system of the al-31 high thrust military aeroengine couldn't connect with the digital control system at all, unless two sets of control components were installed in the Su-27, one for controlling the airframe and the other for controlling the engine. In this way, the Su-27 was an elegant and beautiful man It's the scum man who drives the pilot crazy.

In order to keep the flight performance of Su-27 at a certain level and reduce the burden of pilots, the designers of the Soviet Union had to take the second place and adopt digital analog control to connect with the hydraulic mechanical digital analog control system on the engine.

At that time, the Soviet engineers wanted to solve the problem of the existence of advanced heavy fighters first. As for the more advanced full-power digital electronic control system and the whole machine's digital telex control system, they would make up for each other in the future soviet-27 deeply improved models.

After all, the newly produced Su-27 is not only imperfect in flight control system and engine control system, but almost the whole aircraft has such and such small defects. It is not a perfect aircraft.

As a result, looking forward to the continuous improvement of the Soviet aeronautical engineers, the Soviet aeronautical engineers immediately became Russian aeronautical engineers after the collapse of the Soviet Union. As for the planned fly by wire control and full-power digital electronic control system, they were completely reduced to a mirror.

Under such circumstances, the al-31 high thrust military aeroengine obtained by the 10th project is actually facing the same dilemma as the Su-27.

If we want to use the digital fly by wire control system, we can't match it with the hydraulic mechanical digital analog control system of al-31 high thrust military aeroengine.

Instead of using the digital fly by wire control system, choosing Su-27 and making a compromise according to the actual situation of the aero-engine would be tantamount to self defeating martial arts for the 10th project.

Because the canard wing, tailless delta wing aerodynamic layout of the single engine combat aircraft, if there is no fly by wire control as a blessing, canard wing close coupling simply can not control, it is easy to cause air stall crash.So at that time, Zhuang Jianye put forward this problem is not a blind shooting, but has a strong practical significance.

The problem is whether it is put forward or not, and the No.10 project team can't solve it. As a result, we don't have the experience in the development of full-fledged digital electronic control system. The most important thing is that the Russian made al-31 high thrust military aeroengine is not our own.

You should know that the full digital electronic control system is not a separate electronic control box and a dozen servo devices and sensors.

It is necessary to accurately grasp the data of the whole aero-engine, such as the operation condition, temperature change, speed, power and so on. On the basis of it, the precise control of the aero-engine is realized through advanced algorithm and computer control system.

Without detailed data, there is no foundation. It is impossible for the No. 10 project team to build castles in the air.

When the project team of No.10 project was depressed, the manufacturer of al-31 high thrust military aeroengine, Russian Saturn Aeroengine Design Bureau, suddenly came to the door and told the project team of No.10 project that if they wanted to equip the customized al-31 high thrust military aeroengine with full digital electronic control system, Russian Saturn Aeroengine Design Bureau would be the best choice There is no shortage of technology, talents and equipment. The only shortage is money.

As long as the money of the No.10 project team is in place, it's not a problem to install two Russian girls in the al-31 high thrust military aeroengine, let alone change the control accessories.

As soon as the No. 10 project team saw that time was tight and the task was heavy, it would be a good way to speed up the progress by means of international cooperation. So after a visit to the Saturn Design Bureau, it was immediately convenient for it to sign the technical cooperation framework agreement, and then it would be a waste of money.

However, the project team of Project No. 10 is not stupid either. They know that only spending money to gain benefits is the right way to go. Therefore, in cooperation, on the ground that project No. 10 involves confidentiality, the software programming of the full digital electronic control system of al-31 high thrust military aeroengine, the full digital electronic control system of engine and the digital fly by wire control system of Project No. 10 are combined The integration work has been handed over to Tengfei group, which has excellent technology in industrial software, industrial design software and aviation flight control software.

Tengfei group has never been a loser. How can such a good opportunity be missed? So start from the software, the operation is fierce as a tiger, from then on, the core technology of full digital electronic control system will arrive!
