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

The problem is that in the late 80s and early 90s, the Ascendas Group was in a critical transition period, and many of the most important projects were tightened and gritted on their teeth.

There is simply no energy to develop a full-powered digital electronic control system.

If this is other units, it is estimated that it will be put up, and wait for other projects to be carried out almost, and then return the funds to the full digital electronic control system.

But what kind of person is Zhuang Jianye, that is a ruthless character who is about to go to the black when he sees a way, not to mention, he wants to fight for the status of the international aero engine for the Tengfei collective, and to ascend to the throne of the big brother, it is natural to race against time, and time is not waiting.

But what if you don't have enough resources at hand and don't have enough energy?

It's easy to do, and it's not enough to put such a difficult task on the key model supported by the state.

Project 10 is the most suitable for both horizontal and vertical viewing, as an advanced third-generation fighter, Project 10 was determined to use a fly-by-wire control system from the beginning.

To this end, the mechanical and electrical department of Tengfei Group has also become an important supporting manufacturer of servo motors for the No. 10 project, which is not counting, in order to complete the coordination of the fly-by-wire control system and the airborne electronic system of the No. 10 project, the Tengfei Group also did not hesitate to lose the strong perseverance of the pants, and provided three "science fiction star" test verification special aircraft to the National Test Flight Center.

With such a large amount of money, the advanced combat aircraft made without the full digital electronic control system of the aero engine is simply like the bubbling goddess-level beauty of beauty, and there are two white and tender little pimples on her face, how to look at how imperfect.

In fact, it is.

Due to the successive jumps of domestic high-thrust military aero engines, the installation of domestic engines in the No. 10 project has become a miraculous small probability event.

In order to ensure the goal of putting into operation at the end of the 90s and forming combat capability at the beginning of the 21 st century, the No. 10 project team had no choice but to choose the AL-31 high-thrust military aircraft engine equipped with the Su-27.

However, the thrust of this Russian-made aircraft engine meets the needs of Project 10, but it is somewhat unsatisfactory in terms of engine control system.

Because it uses a set of hydro-mechanical - analog and digital aero-engine control systems finalized in the former Soviet Union in the mid-eighties.

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

However, in terms of performance, there is still a big difference compared to a full-powered digital electronic control system.

This is like a mobile phone, if the full digital electronic control system is an advanced intelligent machine, then the Russians use the hydraulic machinery-analog digital aero engine control system is like a brick big brother.

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

This can be seen from the flight control system of the Su-27, but the cool-looking Su-27 uses a digital analog operating system, which is not a purely 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 aircraft engine produced by the Soviet Union could not be connected to the digital control system at all, unless two sets of control components were installed in the Su-27, one was used to control the fuselage and the other was used to control the engine, but in this way, the Su-27 was an elegant beautiful man, but a scumbag who was crazy for another pilot.

In order to maintain the flight performance of the Su-27 at a certain level and reduce the burden on the pilots, the Soviet designers had to settle for the next best thing, using digital analog control and docking with the hydromechanical-digital analog control system on the engine.

At that time, the Soviet engineers thought that they should first solve the problem of whether there were advanced heavy fighters, and as for the more advanced full-power digital electronic control system and the digital fly-by-wire control system of the whole machine, they would make up for the same in the later Su-27 deeply improved models.

After all, the newly produced Su-27 is not only imperfect in terms of flight control system and engine control system, but almost all the entire aircraft has small defects of one kind or another, and it is not a very perfect aircraft.

As a result, the Soviet aeronautical engineers, who were counting on the continuous improvement of the Soviet Union, waited until the collapse of the Soviet Union, and these Soviet aeronautical engineers became Russian aeronautical engineers in an instant, and the planned fly-by-wire and full-authority digital electronic control systems were completely reduced to a flash in the pan.

Under such circumstances, the AL-31 high-thrust military aviation engine obtained by Project No. 10 actually faces the same dilemma as the Su-27.

I want to use a digital fly-by-wire control system, but I can't match the hydromechanical-digital analog control system on the AL-31 high-thrust military aero engine.

Without the digital fly-by-wire control system, choosing the Su-27 and making a compromise according to the actual situation of the aero engine is tantamount to self-abandonment for Project 10.

Because this single-engine combat aircraft with canard wing and tailless delta wing aerodynamic layout, if there is no fly-by-wire control as a blessing, the close-range coupling of the canard wing cannot be controlled at all, and it is easy to cause a stall and crash in the air.

Therefore, Zhuang Jianye's question at that time was not a blind shot, but had strong practical significance.

The problem is that it has been raised, and the No. 10 project team has no way to solve it, because it has no experience in the development of a full-fledged digital electronic control system, and the most important thing is that the Russian-made AL-31 high-thrust military aircraft engine is not its own.

You must know that the full-authority digital electronic control system is not just a separate electronic control box and a dozen servos and sensors.

Instead, it is necessary to accurately grasp the data of the entire aero engine, such as the operation situation, temperature change, speed size, power strength and so on, and on the basis of it, the precise control of the aero engine is realized through advanced algorithms and computer control systems.

Without detailed data, it is equivalent to having no foundation, and it is impossible for the No. 10 project team to build a pavilion in the sky.

Just when the No. 10 project team was depressed, the Russian Saturn Aero Engine Design Bureau, the manufacturer of the AL-31 high-thrust military aero engine, suddenly came to the door and bluntly told the No. 10 project team that if it wanted to be equipped with a customized version of the AL-31 high-thrust military aero engine equipped with a full-authority digital electronic control system, the Russian Saturn Aero Engine Design Bureau lacked no technology, talents, and equipment, and the only thing missing was money.

As long as the money of the No. 10 project team is in place, the AL-31 high-thrust military aviation engine, not to mention changing the control accessories, is not a problem to install two Russian girls.

The No. 10 project team saw that the time was tight and the task was heavy, and it would be a good way to speed up the progress by means of international cooperation, so after an inspection of the Saturn Design Bureau, it was immediately convenient for it to sign a technical cooperation framework agreement, and then it was a good way to throw money at it.

However, throwing money is throwing money, and the No. 10 project team is not stupid, knowing that spending money to catch the benefits is the big one, so in the cooperation, on the grounds that the No. 10 project involves confidentiality, the software programming of the AL-31 high-thrust military aero engine and the integration of the engine full authority digital electronic control system and the No. 10 project digital fly-by-wire control system of the No. 10 project were handed over to the Tengfei Group, which has excellent technology in industrial software, industrial design software, aviation flight control software, etc., on the grounds that the No. 10 project involves confidentiality.

Tengfei Group has never been the master of losses, where will such a good opportunity be missed? So starting from the software, the operation is as fierce as a tiger, and the core technology of the digital electronic control system will be in hand! 1603355474
