Chapter 746: Improve the engine

"Can we use some of our own parts to replace the parts of this aircraft?" Lieutenant General Dennis Earp suddenly said: "For example, our own radar, to replace the radar on this fighter?"
The aircraft they are going to introduce is mainly technology. In the early stage, they may introduce some complete aircraft, but the subsequent aircraft will definitely be produced in their own factory. This is almost a substitute for their carver project. Product.
It is self-produced, of course, you can use some of your own parts and components, and you can also use David’s, such as radar, they have their own ideas, David’s Elta EL/M-2032 radar, they even more Familiar, easier to integrate your own fire control system.
Qin nodded his opinion: "Of course, but, in this case, we will not be responsible for the after-sales part of the corresponding system."
Hearing what the other party said, Qin Guan knew what the other party was making. If some products from the country of David were used, some of them would say that they were sold to the country of David if they were suspected internationally. No matter how the Patriotic people do it, it has nothing to do with them. Look at the radar above, they are all products of the Davidic Kingdom.
"That's natural." Rafael smiled aside. For them, exporting part of the radar is also profitable.
The Kingdom of David and the Kingdom of Rainbow have maintained a close and friendly relationship, and the Kingdom of David has also made a lot of profits in the arms cooperation with the Kingdom of Rainbow.
Not to mention just the conversion of the old Phantom 3 fighters from Rainbow Nation into Cheetah fighters. The cost of modification is equivalent to twice the cost of buying new fighters.
As for the carver later in history, a light fighter, if it can be built, the cost is twice that of the F-16. There is no way, they have no choice.
"Let's talk about improving the engine." Rafael continued. Whether it can be used and whether Rainbow Country decides to buy it depends on whether these aircraft can be equipped with their own "Ata" 9K-50. engine.
This engine, in the 1970s, Rainbow Country purchased a full set of production technology. Even if some of the parts cannot be produced, they can be purchased secretly from the international community. Therefore, they have no choice but to use this engine. .
Coming to the conference room, a group of technical experts started a discussion.
"This engine is self-heavy and has low thrust." Tu Lao said: "It is difficult to install it on our F-14 fighter."
"Therefore, we intend to adopt a weight reduction program to reduce the weight of the aircraft through the extensive use of composite materials." Rafael said.
Since the engine is not powerful, it can only think of other ways, such as weight reduction.
The use of composite materials to reduce weight is a very good solution. The problem is that it is only in the early 1980s and composite materials in aviation have not been widely used.
Traditional materials used to manufacture aircraft structures include aluminum, steel and titanium. The main benefits of composite materials are reduced weight and simpler assembly.
Compared with aluminum aircraft skins, composite materials can be directly molded and are also lighter in weight, which can enhance the performance of the aircraft.
At present, the real composite material that can be put into use is mainly carbon fiber, represented by the T300 developed and produced by the island country Toray Company. Due to the small force, it can only be applied to secondary parts, such as the leading edge, flap, fairing, rudder And vertical stabilizers.
The Chinese fighter planes use composite materials, and they have just started research and development. I don’t know how long they will be put into use. As for the actual buyers of these rainbow countries, they want to use composite materials, it is too ideal.
"I think we are now pinning our hopes on composite materials, which are castles in the sky." Qin Guan said: "Now, composite materials are not mature, and we have not mastered the technology of using composite materials. How have you mastered it?"
Qin Guan asked, Rafael of the Kingdom of David shook his head.
Although the country of David has strong scientific research capabilities, it is pinned on the Western world, especially the country of Eagle. The fighters and parts they developed are all ordered from the country of Eagle. Composite materials are also produced by the country of Eagle. , It is impossible for them to produce by themselves.
They can't do it, even the Rainbow Nation itself can't do it.
"If we are pinning on a technology that we haven't mastered, the result will be obvious." Qin Guan said: "The progress will be delayed, and ultimately nothing will be achieved."
Once the progress of any project is delayed, the consequences will be unpredictable. The Xiaolong project in history is like this. It is a miracle to walk down hard.
With this project in Rainbow Country, we have been waiting for composite materials, and it turned out to be yellow in the end.
Hearing Qin Guan’s words, several people present nodded:
Yes, Qin, you’re right, but if we don’t lose weight on the plane, then our engine’s thrust is insufficient, and the performance of this fighter jet is very poor. ."
After all, this is just a second-generation turbojet engine. The thrust-to-weight ratio is not high, and the power cannot meet the needs of the F-14. Then this aircraft will become a tasteless one.
"Why don't we want to do something else, for example, to improve the power of our engines." Qin Guan said: "We have experience in research and development, such as the Spey engine that we imported technology from Niu Country. After our improvement, The power has been increased by 17%. As long as you provide us with the full set of information on the engine, we can make the same improvements, develop new compressors, new turbines and electronic control equipment, and increase the thrust of the engine by 10%. There is no problem."
The current afterburner thrust is 70 kN, and if it is increased by 10%, it will be close to 80 kN. This is barely enough, so why bother to make a fuss about the body?
Hearing Qin Guan's words, the eyes of several people present all lit up.
To increase the thrust of the engine, the most important thing is to increase the front temperature of the turbine. As long as the turbine blades are replaced with new high-temperature resistant turbine blades, the temperature and power can be increased.
But in this case, more air is needed to participate in the combustion, that is, a new compressor is needed to blow in more air, so the overall modification is needed.
Perhaps before, our side had no experience, but through the improvement of the Spey engine, we have accumulated a lot of experience. It is no problem to improve the turbofan engine, and the small turbojet is not a problem.
In this way, if the other party provides funds, the research and development process is carried out by the other party, the overall level of the team can be greatly improved.
Moreover, it can make a fortune.
There is no possibility for the other party to refuse. After all, if this engine modification is successful, it can also be installed on their existing Mirage 3 and continue to improve its performance. This is definitely a happy ending.
