Super Weapon Exchange System

The Super-7 fighter is said to have been greatly improved on the basis of the J-7 fighter. What Niu is most interested in is how did the Han people come up with such an advanced aircraft on the basis of backward technology?

Last year's flight show, James is still fresh in his memory!

Now, I’m finally going to see the advanced Super VII. You can observe this fighter from close range. You are definitely the first batch. Han’s technology is definitely lagging behind, but it can’t keep the advanced sub-projects. .

With such a mood, James, as other people walked in, the smooth-looking fighter stood there waiting!

"Super seven, so beautiful!" When the people from Date Palm saw it, they couldn't help but let out a cry.

A good airplane, first of all, if it is a beautiful airplane, the current Super Seven looks absolutely better than the MiG 21 series with wings on a stick. The wing-body fusion layout looks tall and tall. what!

Everyone is getting closer, and as they keep getting closer, they also start to have doubts in their hearts. In short, it looks like something is wrong!

Then, getting closer and closer, James suddenly found something: "This plane does not seem to have an engine installed?"

For an aircraft, it can be roughly divided into three parts, the body, the engine, and the 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 bit solemn: "We don't have a suitable engine to assemble it."

"Impossible, how did your previous plane fly?" James immediately asked, now, take an empty shell to tease us? Who are you coaxing! The maneuverability of the air show at that time was not weak!

"That was a special case at the time." Qin Guan said: "We have made a slight improvement on the basis of our original turbojet-7 engine, and raised the turbine temperature. In this way, we can greatly increase the thrust. Yes, the price is that the life span is very short. As long as one flight, the engine is scrapped.

Improving the original turbojet engine and increasing the turbine temperature is also related to the magical turbine blade Qin Guan said. As long as the turbine temperature can be increased, the power of the engine can be increased. However, after all, it is not an overall coordinated design. In addition, Han has no technical reserves of engines, so even though they have increased their power, they have been exhausted, and the engines will be scrapped once they fly.

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

When Amir finished speaking, Abid, who had followed him, spoke. He had heard of it: "In the eyes of various analysts in the aviation industry, this aircraft has reached the level of a quasi-three-generation aircraft, but Because Han Guo did not disclose the specific data, it was only speculation. When I came, I wondered if I could see this aircraft. I did not expect to see it."

"How does that compare to Mirage 2000?" Amir asked.

After all, Amir is not the most professional. Now that I heard Abid's admiration, I could not help but plan to compare it with Mirage 2000.

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

The specific price is still uncertain, because the cost of engines and avionics is uncertain.

Hearing this, Amir couldn't help but be moved.

Yes, the date palm country is rich in wealth, but if good steel is used for the blade, if you have money, you have to find a suitable method. If the performance is the same, the price is only one-third, it is definitely a good deal. .

However, this must be done carefully, because this aircraft does not yet have an engine.

On the tank project, Amir directly decided to invest in research and development. This was due to many reasons.

The army of the Date Palm Nation was formed almost in accordance with the model of the Bear Nation. In their thinking, it was also the traditional Continental Army idea. Therefore, the most important thing is the ground troops.

Tanks are of course the most important thing. It is worth investing in tanks.

In contrast, Europa has no new tanks that can be easily obtained. They can only take the foreign trade path of the bear country, but the bear country is too pitted.

The Han State already has advanced tanks. Although the 79 tanks they say are newly developed, people with a discerning eye will know that it is the imitation Leopard-2. Han State has already equipped Leopard-2 and introduced technology. Therefore, the risk of R&D is not great.

But the fighter plane is different. Han has never had a self-developed fighter plane. For the first time, it is this kind of advanced third-generation fighter plane. The risk is definitely high, and there is no engine yet.

Therefore, the date palm country people chose to watch from the sidelines. At this time, they can't speak immediately. Let's listen to what these cattle country people say.

Niu Guoren, of course happy.

The Rolls-Royce company builds aero engines! This time, if it can promote the engine transaction, isn't it possible to make another profit?

He quickly started thinking in his mind, what kind of engine is the best on this kind of airplane? It's definitely not Spey, Spey is too thick, this aircraft should be the most suitable for mid-push.

Speaking of China Push, don’t you have one?

Stanley suddenly remembered that the RB199 engine he used on the Tornado fighter was coming.

The Tornado fighter-bomber is a fighter jointly developed by several countries in Europa. The engines in it can be considered as jointly developed, but Rolls-Royce is absolutely dominant.

This is a three-rotor afterburner turbofan engine with high thrust-to-weight ratio. (If you are familiar with engines, you should know that the three-rotor is unique. In this case, the M53 in the same period is still a single-rotor, while the other three-generation engines are dual-rotors. Why? Because the three-rotor is too complicated!

In 1965, Niu Guo proposed the RB199 program. In 1969, Rolls-Royce, MTU and Fiat formed a turbine joint company to start the design. The first RB199 engine was tested for the first time in 1971, and the first test flew on the flight test bed in April 1973. In 1974, it was installed on the "Storm" prototype for the first test flight. In November 1978, it passed the 150h finalization test. Mass production started in 1979.

In other words, this engine belongs to the most advanced engine that has just been finalized!

Its thrust reached 71 kN, and its thrust-to-weight ratio was close to 8. Compared with Spey, it was definitely one level ahead. It can provide the short-time maximum afterburner thrust required for short takeoff, the non-extended thrust required for low-altitude penetration and air patrol, and the larger remaining thrust required for the violent maneuver of the aircraft.

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

Now, I am really unintentional. I was thinking about coming to discuss the turbine blades promised by the Han people, but I did not expect that the Han people actually have a demand for engines!

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

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