If you compare the performance on paper purely from the numbers,R73 must be the best,In addition to this off-axis launch angle,What is the maximum range、Maneuvering overload, etc.,These indicators are better than the Monster Snake3,And,R73Another important skill,It can also be matched with the helmet aiming system,The concept of this thing is very advanced,Missile aiming at the target only requires the pilot to move his eyes,Killing with eyes has become a reality,It is definitely a dog fighting artifact to see where to fight。

However, after China introduced the Su-27, it can be found that no matter how good the performance of the R73 missile is, it has not been integrated into its own system, and at the same time, on the localized J-11 fighter, it is the Thunderbolt-8 missile that is integrated into it, and this R73 missile is only used in the purely imported and early assembly of the Su-27 fighter, so what is the reason for it?

Despite the advanced performance on paper, however, R73 technology from the Soviet Union, its production is not reliable, missiles often have some small problems, especially the anti-jamming ability is not high, and the introduction of the Monster Snake 3 project, in addition to the introduction of an advanced combat missile, but also learned a complete set of production processes and quality management systems of Western standards, compared to the former, the latter is more effective, an advanced system, affecting the entire industry, on this basis, the domestic continuous improvement of Thunderbolt-8, It has become an excellent combat missile, so the R73 is just a product of a period, and after the purely imported fighters are retired, this missile will be put into the cold palace.

Now, in everyone's eyes, they are full of curiosity about this missile, and its performance is so advanced that it makes people drool with envy, but everyone is still interested, and they didn't put forward anything about the introduction of technology production like Qin Feng again.

Moreover, there is already a Thunderbolt-8 in China, and it is enough to have an advanced air-to-air missile, which cannot be chewed on as much as it wants, and there will be no duplication of construction in China, and it will cost a huge amount of money to build a completely different missile production line.

The weapon system is roughly understood here, and now, there is one important thing left that needs to be learned in detail from Simonov.

That is, the engine of the Su-27.

Advanced fighters are inseparable from advanced engines, the performance of the Su-27 is so good, and it has a lot to do with the engine it is equipped with, in China, this engine has been called the third uncle, the nickname is Qin Fengqi, and it quickly spread.

"The engine used by our Su-27 was developed by the Rurika Design Bureau from 1973, and until 1985, the indicators of this engine were stable, passed the acceptance, and became the power system of the Su-27 fighter." Simonov said that just these numbers are enough for many people to sigh in their hearts, this is the difficulty of engine development!

This kind of high-thrust engine took more than ten years to develop successfully, you know, the Soviet Union in terms of aviation power, and the United States is neck and neck, belonging to the two hegemons, even they have to use such a long time, so, what about their own side?

Your own turbofan ten has begun to set up the project, and this engine, the plan is to match the J-10, now it seems that this engine wants to be developed successfully, it must not be able to catch up with the research and development progress of the J-10.

"Our engine is a common twin-rotor turbofan engine, with a maximum afterburner thrust of 12 tons and an intermediate thrust of 7.6 tons.

An engine must not only have advanced indicators, but also have a high degree of reliability, the research and development of domestic engines, the indicators are very high, but when it comes to reliability, even the bench test may not pass, let alone equip the fighter.

The reliability of the third aunt is quite high, and it is precisely because it is very reliable, so when the fighter does various actions in the air, the engine can work stably and normally, and there will be no unexpected problems. Surge, for example, has plagued Tomcat fighters for so long that pilots have to be careful with their engines.

As for the domestic engine, such as the turbofan six, there is no need to install a test flight, just on the test bench, it has already begun to surge violently.

This is mainly related to the compressor of the engine, and the surge starts from the stall of the compressor, and the engine of this fighter completely interprets the simple and crude aesthetics of the Soviet military-industrial system.

"At the same time, the maintenance of this engine is also very simple, it adopts a unit structure, the whole engine is composed of 14 units, after the engine has a problem, it does not need to be replaced, only the faulty unit can be replaced."

Even Soviet engines began to pay attention to modularity, which could greatly reduce the cost of maintenance.

"What is the life of this engine?" General Lin asked, this is also a very important issue, the life of the engine, directly determines the cost of the aircraft in the whole life period, if the engine life is short, in the whole life of the aircraft, to replace the engine several times, that is all money.

"Its lifespan is far greater than that of other fighters, and it is now designed to have a lifespan of 1,000 hours, and when it reaches 1,000 hours, it can be rejuvenated through overhaul."

Compared with the previous hundreds of hours, the current engine of 1,000 hours is already very high, which is also what makes Simonov complacent, but if compared with Western engines, the gap is still not small.

The life of a fighter plane should be at least four or five thousand hours, which means that the engine must be replaced several times during its life.

"It seems that if we are going to introduce this kind of aircraft, we must introduce an overhaul line for the engine." General Lin said seriously.

Aero engine long-term work in high temperature, high pressure, high speed of the harsh environment, when the work reaches a certain time, it is necessary to maintain and maintain the engine, some of the easily damaged parts, such as bearings, seals, etc. to replace, and with the use of in-depth, it is also necessary to disassemble the entire engine, after all disassembled, the relevant parts are cleaned, metal flaw detection, what deformation, cracked parts are all replaced, and finally the engine is assembled, and the ground test is carried out. After determining the state of the engine and passing it, an overhaul of the engine is completed.

After all, after the engine reaches the end of its life, it is impossible to throw it away directly, disassemble and overhaul it, reassemble it, it is necessary, if there is no such overhaul line in the country, then it is still inseparable from the Soviet Union, and it must be sent to the Soviet Union for overhaul, which will not only cost money, but also may turn the fighter into scrap metal after the situation changes in the future.
