Speaking of the 606 Institute in the north of the Republic, it should be regarded as the most technical unit in the aero engine industry of the Republic at present, and there is no one, although the design institute has produced a lot of moths, but compared with the country, it is the only tall man who can see the eyes of the short man after all.

After all, the turbofan 6 project has been discontinued, the institute has no project at hand, as a key military unit of national defense, it is impossible to disperse like this, whether it is to maintain the design team, or for other reasons, it is necessary to launch another project.

When the plane was raised, the 606 Institute began to conduct pre-research and demonstration in Taihang in the early eighties, and after the official launch of the tenth, the project was officially established in the mid-to-late eighties, and finally it was a bumpy journey.

After careful calculation, Taihang was officially launched in the mid-to-late eighties, so what was the place doing in the early eighties?

There is no doubt that it is naturally another well-known engine: the turbojet 14, which was originally planned to be used for the J-83 project and the subsequent improvement of the J-7, but due to various reasons, it was not officially put into service in the end.

For the turbojet 14, in fact, it is not good or bad, at least its existence has played a certain positive role in the aircraft engine industry of the republic.

"606 on the new push? This is a good thing, we can't put the super seven, J-8 power system all pressed on the RB-199 engine, after all, it is a British product, it is okay to use it as a temporary emergency, but we still have to have a product that we can get our hands on after all. ”

The north has launched the middle push engine, which has no competition with the Spero reform developed by Southwest Power Machinery and Luo Luo, Wang Zhengguo naturally has no opinion, and is even very happy.

The only thing that is still a little worried is probably to see if this guy still continues to simply take out the first seven high-pressure compressors of the Spey engine like the upper plane and use it directly.

The result of this is that the high-pressure compressor and the low-pressure compressor do not match later, which has plagued the progress of the turbojet 14 engine for several years.

Although the design institute later tried to solve these problems, the various problems brought about by it still made this engine riddled with evil diseases, and even directly dragged the J-83 who assembled this engine to death.

In fact, the 601 Institute in the north of the Republic is also a sincere and honest person, and the J-83 project purchases all mature shelf products except for the engine, and the only thing that took the risk is the power system, but the result is that the power system is out of the basket.

Counting carefully, many of the military fighter projects independently developed by the Republic were all killed by the engine of the 606 Institute.

The Jian-9 of the Shudu Institute was scheduled to install the turbofan 6 engine of the 606 Institute, but the final result was that the turbofan 6 was dismounted because of the serious lag of the turbofan 6; the Jian-83 of the 601 Institute was scheduled to install the turbojet 14 engine of the 606 Institute, and the final result was that the turbojet 14 was dismounted because of the serious lag of the turbojet 14.

Fortunately, after this Shudu suffered a loss, he decided not to play with the 606 Institute of mud, and would rather use the 410 factory to copy the Soviet turbojet 15 engine, rather than use Taihang, although the 10th did not go on the turbojet 15, but it was finally successful.

Compared with the clever strength of Shudu, which has eaten a trench and grown a wisdom, the final development is quite good, and the 601 Institute that was also pitted by 606 is really honest and kind!

Not long after J-83 got off the horse, the 601 Institute got the J-11 project again, and this guy actually continued to press the Taihang engine of the 606 Institute, which is really a model of not being afraid of death, absolutely touching.

On the upper plane, sometimes when Wang Zhengguo sees the overwhelming spraying of 601 on the Internet, someone will actually have some emotions in his heart, and he will be inexplicably moved.

That is, the persistence of the 601 Institute, which finally ushered in the maturity of the Taihang engine, from this point of view, in fact, the Northern Institute also has its shining point.

"Conservative" and "backward" are the labels on it, but in other words, it is not wrong to describe it as "down-to-earth" and "obscure".

A country, especially a big country, needs to have a variety of good qualities and cultures, and if there is no 601 Institute of firm support for national development, it will also turn to imported Russian development, then the result may be ......

"Mr. Tu, although you are in a hurry in the early stage of the super seven project, you can only use imported RB-199 engines, but I still hope that you can support Guofa as much as possible in the follow-up. ”

Wang Zhengguo is afraid that this time it will be like the upper plane, the turbojet 14 will develop to the end, the J-7 series will not be wanted, and the J-83 will also be finally dismounted, so the result of the turbojet-14 engine will be ......

In the early days, the Taihang engine on the upper plane was actually not less than the failure of the turbojet 14, but in the end, it was because the organic type insisted on using it, which developed and matured, so whether the engine is mature or not depends not only on the design and production, but also on the actual installation rate.

"Of course, we are willing to support the national development, the country has its own engine, who will have nothing to do to run to use imports, and this new push is a joint project between the army and the ministry, and it is clear that it is a domestic power system that will be changed by super seven and J-eight. ”

What engine is used in an aircraft, as the chief engineer of the project, Tu Jida only has the right to suggest, not the right to make the final decision, whether it is the new Zhongtui or RB-199, there is actually not much difference for it.

However, he also had some complaints about the new push engine itself: "However, I heard that the new push of the 606 Institute still took the turbojet engine route, which is a little incomprehensible, and now the world is a turbofan engine, and we continue to spend great efforts to develop a turbojet, which seems a little ......."

In the 80s, a new turbojet engine was developed, which did not sound very good, which was simply anti-human and anti-anachronism.

The reason why the turbojet-14 project in the upper plane was sprayed so badly is not only because the engine itself is riddled with failures, but also because the ID card of the turbojet engine is also the "original sin".

So, is the vortex really that unbearable?

I'm afraid this is still up for debate, in the case of detaching from the needs of the aircraft model itself, it is better to talk about turbojet or turbofan in isolation, which is itself a kind of hooliganism.

"Mr. Tu, on the question of turbojet or turbofan, I don't think there is any need to be too entangled, just according to the super seven and J-8 changes that we want to install, these two aircraft are positioned in the needs of the territorial air defense air force, and in the case of aircraft interception requirements, it is not a mistake to develop turbojet engines. ”

The military fighters of the eighties and nineties were indeed in service with products that focused on subsonic maneuvering at medium and low altitudes, so the turbofan engine could have a very good performance, but after 2000, the situation was very different.

Needless to say, the generation of artifact F-119, that guy said that it was a turbofan engine, but in terms of bypass ratio, its flight quality is infinitely close to that of a turbojet engine, which shows that in the future demand, turbojet engines still have a market.
