If you want to be a big brother, you have to be willing to invest.
The problem is that the Ascendas Group in the late 1980s and early 1990s was in a critical period of transformation, and many important projects were carried out while tightening the belt.
There is simply no energy to develop a full-power digital electronic control system.
If it were other units, they would probably put it aside and wait for other projects to be almost completed before withdrawing funds to launch the full-power digital electronic control system.
But who is Zhuang Jianye? He is a ruthless character who will end up in trouble if he sees a path. What's more, he wants to fight for Tengfei Group's status in the international aviation engine field and ascend to the throne of the big brother. Naturally, every second counts. Time waits for no one.
But what should we do if we don¡¯t have enough resources and energy?
It¡¯s easy to handle, just put such a difficult task on key models supported by the state.
Project No. 10 is most suitable when viewed horizontally and vertically. As an advanced third-generation fighter jet, Project No. 10 was determined to use a fly-by-wire control system from the very beginning.
For this reason, the electromechanical department of Ascendas Group has also become an important supporting manufacturer of servo motors for Project 10. Not only that, in order to complete the coordination of the fly-by-wire control system and airborne electronic system of Project 10, Ascendas Group did not hesitate to put down its pants. With his strong perseverance, he provided three "Science Fiction Star" special aircraft for test verification to the National Flight Test Center.
After spending such a huge amount of money, the advanced combat aircraft produced, without the full digital electronic control system of the aero-engine, looks just like a goddess-level beauty with effervescent beauty, but there are actually two small white and tender pimples on her face. , no matter how you look at it, it¡¯s not perfect.
??In fact, this is indeed the case.
Because domestic high-thrust military aviation engines have been delayed one after another, the inclusion of domestic engines in Project 10 has become a miraculous and low-probability event.
In order to ensure that it would be put into production in the late 1990s and achieve combat capability in the early 21st century, the Project 10 project team had no choice but to use the al-31 high-thrust military aviation engine equipped on the Su-27.
However, the thrust of this Russian-made aeroengine meets the requirements of Project 10, but the engine control system is somewhat unsatisfactory.
Because it uses a hydraulic mechanical-analog digital aircraft engine control system that was finalized by the former Soviet Union in the mid-1980s.
Overall, it is not as complex and anti-human as the traditional hydraulic mechanical control system. A lot of electronic components have been added to simplify the control mechanism.
But in terms of performance, there is still a big difference compared to full-power digital electronic control systems.
This is like a mobile phone. If the full-power digital electronic control system is a smart phone with advanced performance, then the hydraulic mechanical-analog digital aircraft engine control system used by the Russians is as big as a brick.
It can only be said that it is slightly better than the traditional hydraulic mechanical control system.
This can be seen from the flight control system of the Su-27. 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 was not that the Soviet Union did not want to use a digital fly-by-wire control system at that time, but because the control system of the al-31 high-thrust military aeroengine produced could not be connected to the digital control system unless two sets of control components were installed on the Su-27. , one set is used to control the airframe, and the other is used to control the engine. But in this way, the Su-27 is an elegant handsome man, but a scumbag that drives the pilot crazy.
In order to maintain the flight performance of the Su-27 at a certain level and reduce the burden on the pilots, Soviet designers could only settle for the second best, using digital simulation control and connecting the hydraulic machinery-digital simulation control system on the engine.
At that time, Soviet engineers thought that they should first solve the problem of the availability of advanced heavy-duty fighters. As for the more advanced full-authority digital electronic control system and the digital fly-by-wire control system of the entire machine, they would be the same in future deeply improved models of the Su-27. Make up for it.
After all, the newly produced Su-27 not only has imperfect flight control and engine control systems, but almost the entire aircraft has small flaws of one kind or another. It is not a perfect aircraft.
As a result, the Soviet aeronautical engineers who were counting on subsequent continuous improvements waited until the Soviet Union disintegrated. These Soviet aeronautical engineers instantly became Russian aeronautical engineers. As for the planned fly-by-wire control and full-power digital electronic control systems, they were completely Become a mirror and a moon in the water.
Under such circumstances, the al-31 high-thrust military aeroengine obtained by Project 10 is actually facing the same dilemma as the Su-27.
I want to use a digital fly-by-wire control system, but there is no way to combine it with the hydraulic machinery-digital analog control system on the al-31 high-thrust military aeroengine.match.
?????????????????????????????????????????????????????????????????????????? did away with the Su-27 and make compromises based on the actual conditions of the aero-engine, it would be tantamount to abandoning martial arts for Project 10.
Because this single-engine combat aircraft has a canard wing and a tailless delta wing aerodynamic layout, if it is not supported by fly-by-wire control, the close coupling of the canard wing cannot be controlled at all, and it can easily cause a stall and crash in the air.
So when Zhuang Jianye raised this issue, it was not just a random issue, but it had a strong practical significance.
The problem has been raised, and the No. 10 project team has no way to solve it. As a result, they have no experience in the development of full-power digital electronic control systems. The most important thing is the Russian-made al-31 high-thrust military aviation. The engine is not your own.
You must know that a full digital electronic control system is not just a separate electronic control box and a dozen servo devices and sensors.
Rather, it is necessary to accurately grasp the various data of the entire aeroengine, such as operating conditions, temperature changes, rotational speed, power strength and other data. On this basis, advanced algorithms and computer control systems are used to achieve aviation control. Precise engine control.
Without detailed data, there is no foundation. No matter how the No. 10 project team is doing, it is impossible to build castles in the air.
Just when the No. 10 project team was depressed, the Russian Saturn Aeroengine Design Bureau, the manufacturer of the al-31 high-thrust military aeroengine, suddenly came to the door and told the No. 10 project team bluntly that if they wanted to equip them with full power A customized version of the al-31 high-thrust military aeroengine with a digital electronic control system. The Russian Saturn Aeroengine Design Bureau has no shortage of technology, talent, or equipment. The only thing it lacks is money.
As long as the money for the No. 10 project team is in place, it will not be a problem to install two Russian girls on the al-31 high-thrust military aeroengine, let alone the control attachments.
The Project 10 project team saw that the time was tight and the tasks were heavy. It would be a good idea to use international cooperation to speed up the progress. So after an inspection of the Saturn Design Bureau, they immediately facilitated the signing of a technical cooperation framework agreement, and then Throwing money at all kinds.
However, spending money is money, and the No. 10 project team is not stupid. They know that spending money to catch the benefits is the most important, so during the cooperation, they used the al-31 high-thrust military aeroengine as an excuse for the No. 10 project to be confidential. The software programming of the full-authority digital electronic control system and the integration of the full-authority digital electronic control system of the engine and the digital fly-by-wire control system of the No. 10 project were handed over to experts in industrial software, industrial design software, aviation flight control software, etc. Ascendas Group.
Ascendas Group has never been one to suffer losses. How could it let such a good opportunity pass? So we started with the software, and the operation was as fierce as a tiger. From then on, we had the core technology of the full-power digital electronic control system!
