Chapter 436

The super-7 fighter is said to have been greatly improved on the basis of the Jian-7 fighter. Niu Guo is most interested in how the Han people came up with such an advanced aircraft on the basis of backward technology?

James still remembers the flight show last year!

Now, we finally want to see the advanced super seven. We can observe this fighter closely. Our side is definitely the first batch. The technology of the Han country must be backward, but we can't guarantee that there are advanced sub projects.

With such a mood, James walked in with the others, and the smooth fighter stood there waiting!

"Super seven, it's so beautiful!" when the people of the date country saw it, they couldn't help shouting.

A good plane, first of all, if it is a beautiful plane, the current super seven looks much better than the MIG 21 series with wings on a stick. The layout of wing body integration is tall!

Everyone approached. As they approached, they began to have doubts in their hearts. In short, there seemed to be something wrong!

Then, close, close, James suddenly found something: "this plane doesn't seem to have an engine?"

For an aircraft, it can be roughly divided into three parts: body, engine and avionics, each accounting for one third of the cost. Now, there is no engine behind!

"Yes." the expression on Qin Guan's face was a little dignified: "we don't have a suitable engine to assemble it."

"No way, how did your old plane fly?" James asked immediately. Now, tease us with an empty shell? Coax who! At that time, the mobility of the flight show was not weak!

"That was a special case at that time." Qin Guan said, "we improved our original turbojet-7 engine slightly and increased the turbine temperature. In this way, we greatly increased the thrust. The price is that the service life is very short. As long as we fly once, the engine will be scrapped."

Improving the original turbojet engine and increasing the turbine temperature is also related to the magical turbine blade mentioned by Qin Guan. As long as the turbine temperature can be increased, the power of the engine can be improved. However, after all, it is not an overall coordinated design, and the Han country has no technical reserve of engine. Therefore, although they have increased the power, they do their best, Let the engine fly once and discard it.

"Is this aircraft very powerful?" Amir asked. He didn't quite understand.

After Amir said that, abid, who followed him, spoke. He had heard of it: "in the aviation industry, in the eyes of various analysts, I think this aircraft has reached the level of quasi third-generation aircraft. However, because the specific data have not been disclosed in China, I can only speculate. When I came, I wanted to see this aircraft. Unexpectedly, I really saw it."

"What about phantom 2000?" Amir asked.

Amir is not the most professional after all. Now that abid appreciates it so much, he can't help but plan to compare it with phantom 2000.

"If you replace it with a suitable engine, I can guarantee that its performance is comparable to that of phantom 2000, but the price is at most one-third of that of phantom 2000."

The specific price cannot be determined, because the cost of engine and Avionics is uncertain.

Hearing this, Amir couldn't help being moved.

Yes, the date country is rich and powerful, but if good steel is used on the blade, you have to find a suitable flower method. If the performance is the same, but the price is only one-third, it is definitely a cost-effective business.

However, this has to be cautious, because this aircraft has no engine.

In the tank project, Amir directly decided to invest in research and development, which is for many reasons.

The army of yezao state is almost established according to the model of bear state. In their thoughts, it is also the traditional idea of the Continental Army. Therefore, the most important thing is the ground force.

Of course, tanks are the most important. It is worth investing in tanks.

In contrast, there are no new tanks in Europe. They can only take the foreign trade path of bear country, but bear country is too pit.

The Han country already has advanced tanks. Although the 79 tanks in their mouth are newly developed, the discerning people know at a glance that it is clearly the imitation leopard-2. The Han country has been equipped with leopard-2 and introduced technology. Therefore, the risk of R & D is not large.

But the fighter plane is different. There has never been a self-developed fighter plane in the Han Dynasty. This is the first time that this advanced third-generation aircraft must be risky. Moreover, there is no engine at present.

Therefore, the people of yezao chose to watch first. At this time, they can't speak immediately. Let's listen to what these Niu people say first.

Niu Guoren, of course.

Luo Luo company is a manufacturer of aeroengines! This time, if we can promote the engine trade, can we make another profit?

He soon thought in his mind, what is the best engine for this kind of plane? It's definitely not Spey. Spey is too thick. This plane should be the most suitable for zhongtui.

Speaking of zhongtui, don't you have one?

Stanley immediately remembered the rb199 engine used by his side in the gale fighter.

Gale fighter bomber is a fighter jointly developed by several countries in Europe. Its engine is also jointly developed, but RORO is absolutely dominant.

This is a high thrust to weight ratio three rotor afterburner turbofan engine. (if you are familiar with the engine, you should know that there are only three rotors. For this one, the M53 in the same period is still a single rotor, while the other three generations of engine are all double rotors. Why? Because the three rotors are too complex!)

In 1965, Niu Guo proposed the rb199 scheme, and in 1969, Rolls Royce, MTU and Fiat formed a turbine consortium to start the design. The first rb199 engine was tested for the first time in 1971 and the first flight test was conducted on the flight test bench in April 1973. In 1974, it was installed on the "gale" prototype for the first test flight. It passed the 150h type test run in November 1978. Mass production began in 1979.

In other words, this engine belongs to the most advanced engine just finalized at present!

Its thrust has reached 71 kn, and its thrust weight ratio is close to 8. Compared with Spey, it is definitely one level ahead. It can provide the short-time maximum afterburner thrust required for short-range takeoff, the non afterburner thrust required for low altitude penetration and air patrol, and the large residual thrust required for severe maneuvering of aircraft.

If only equipped with the gale fighter, the purchase volume of this engine will be relatively small. The problem is that the purchase cost is very high. If it can be sold, the production quantity will be more, and the cost can be reduced.

Now, it's really unintentional to insert willows into the shade. I wanted to come to the Han people to discuss the promised turbine blades. Unexpectedly, the Han people actually have the demand for engines!

"We have an engine suitable for this fighter," Stanley said immediately. "However, we only provide the whole machine and will never output engine technology."

Providing products, on the one hand, providing technology, on the other hand, Spey is a backward second-generation engine, which can output technology. As for the latest engine, of course not!
