Super Weapon Swap System

"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 want to introduce is mainly technology introduction. At the initial stage, some complete machines may be introduced, but the subsequent aircraft must be produced in their own factory, which is almost a substitute for their sculptor project.

Of course, they can use their own parts to replace their own production. At the same time, they can also use Davidson's radar. For example, they have their own ideas. Davidson's elta El / m-2032 radar is more familiar and easier to integrate their own fire control system.

Qin Guan nodded: "of course, but in this case, we will not be responsible for the after-sales part of the corresponding system."

Qin Guan knew what the other party was up to. If he used some products of the kingdom of David, in case of international suspicion, some of his own said that his own side was sold to the kingdom of David. No matter what the people of the kingdom of David did, it had nothing to do with his own side. Look at the radar above, they were all products of the kingdom of David.

"That's natural." lafar laughed. For them, exporting some radar is also profitable.

David and rainbow maintain close and friendly relations, and David has also made a lot of profits in its arms cooperation with rainbow.

Besides, just refitting those old mirage 3 fighters of rainbow country into cheetah fighters, the cost of refitting is equivalent to twice the cost of buying new fighters.

As for the sculptors in later history, if a light fighter 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." lafar continued. Whether it can be used and whether rainbow country decides to buy depends on whether these aircraft can install their own "atta" 9k-50 engine.

In the 1970s, rainbow Kingdom purchased a full set of production technology for this engine. Even if some parts could not be produced, they could also secretly buy it from the world. Therefore, they had no choice but to use this engine.

When they came to the conference room, a group of technical experts began to discuss.

"This engine is self-supporting and has low thrust," said Tu Lao. "It's difficult to install it on our j-14 fighter."

"Therefore, we intend to adopt the weight reduction scheme and reduce the weight of the aircraft through the extensive use of composite materials," lafar said.

Since the engine suck, it can only be done from other aspects, such as weight loss.

Using composite materials to reduce weight is a quite good scheme. 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 make aircraft structures include aluminum, steel and titanium. The main benefits of composites are reduced weight and simpler assembly.

Compared with the aluminum aircraft skin, the composite material can be formed directly and has light weight, which can enhance the performance of the aircraft.

At present, the composite materials that can really be put into use are mainly carbon fiber, represented by T300 developed and produced by Toray company. Due to the small force, it can only be used in secondary parts, such as leading edge, cover, fairing, rudder and vertical stabilizer.

The fighters in the Han Dynasty use composite materials, which have just been developed. I don't know how long it will take to put them into use. As for the actual buyers in the rainbow country, it's too ideal to apply composite materials.

"I think we now place our hopes on composite materials, which is a castle in the air." Qin Guan said: "now, composite materials are not mature, and we have not mastered the use technology of composite materials. How are you doing?"

Qin Guan asked, and lafar of the kingdom of David shook his head.

Although David has strong scientific research ability, it is pinned on the western world, especially Eagle country. The fighters and parts developed by them are ordered from Eagle country. Composite materials are also produced by Eagle country. Now, it is impossible for them to produce by themselves.

They can't, and rainbow country itself can't.

"If we rely on a technology we haven't mastered yet, the result is obvious." Qin Guan said, "the progress will be delayed and even nothing will be achieved in the end."

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.

And the project of rainbow country has been waiting for composite materials, and then it will turn yellow in the end.

Hearing Qin Guan's words, several people present nodded: "yes, President Qin, you're right. However, if we don't lose weight on the plane, our engine thrust is insufficient, and the performance of this fighter is very poor."

After all, this is just a second-generation turbojet engine. The thrust weight ratio is not high, and the power can not meet the needs of the j-14. Then this aircraft will become a chicken rib.

"Why don't we think of other ways, such as improving the power of our engine?" Qin Guan said: "We have experience in research and development. For example, we have imported technology from NiuGuo to produce Spey engine. After our improvement, the power has increased by 17%. As long as you provide us with a full set of information about the engine, we can make the same improvement, develop new compressors, new turbines and electronic control equipment, and increase the thrust of the engine by 10%, There is no problem. "

Now the afterburner thrust is 70 kn. If you increase it by 10%, it will be close to 80 kn. This is barely enough. Why make a big fuss on the body?

Hearing Qin Guan's words, several people present brightened up.

If you want to increase the thrust of the engine, the most important thing is to increase the front temperature of the turbine. As long as you install new high-temperature resistant turbine blades, you can increase the temperature and power.

However, in this case, more air is needed to participate in combustion, that is, a new compressor is needed to blow more air. Therefore, it needs to be modified as a whole.

Maybe we had no experience in the past, but we have accumulated a lot of experience through the improvement of Spey engine. There is no problem in improving turbofan engine, and a small turbojet is nothing more.

In this way, if the other party provides funds, the other party carries out research and development, and goes through the research and development process, the overall level of the team can be greatly improved.

And you can make a lot of money.

The other party has no possibility to refuse. After all, if the engine modification is successful, it can also be installed on their existing phantom 3 to continue to improve its performance, which is definitely a happy ending.
