Chapter 2618

"Mr. Song, are you going to build an air and space fighter?" Qin Guan seriously said: "it requires all-round breakthroughs in materials, technology, engines and so on. I'm afraid it will take a long time?"

The aerospace fighter is different from the current ordinary fighter. You know, no matter how the technology of the fighter develops, the speed hardly exceeds Mach 2.5. If it exceeds, it should use titanium alloy or stainless steel. Now there are only two or three models in the world.

Aerospace fighter, if you want to enter space, this speed is not a problem of doubling or doubling. When you go out of space, you need 7.9 kilometers per second, 20 times the speed of sound!

Even Qin Guan himself didn't think about it. In his plan, this kind of air and space fighter should be left to others to worry about. He just had to do well in the present.

"Yes, we need a lot of technology and breakthrough materials. However, we must not refuse to go because of difficulties. As long as this direction is correct, we must bravely go up. If the road is long, why don't we start early?"

Old song is now persuading Qin Guan.

"Just ten years ago, our fighters were still second-generation aircraft, but now, we can see that our main equipment has been replaced by third-generation aircraft, and the fourth-generation aircraft will soon start service. As military workers, the equipment generation, test flight generation and pre research generation should be carried out simultaneously, so that the research and development of aviation equipment can embark on a sound development Track and continue to develop the advantages we have accumulated. "Old song said: "I firmly believe that as long as we move forward, we will be able to succeed. Step back and say, even if I can't see it, there are our next generation of scientific research workers. Now, the fourth generation aircraft will be put into service, and the research and development of the fifth generation aircraft must begin. President Qin, we believe that with you, we will be able to succeed in research and development! Without you, even if it depends on me With our own scientific research strength, we will be able to develop successfully! "

What song Lao said moved Qin Guan.

Yes, we must plan ahead. Now, the fourth generation aircraft is about to enter service. We can't sleep on the victory seat of the fourth generation aircraft. We must continue to carry out research and development!

Fifth generation aircraft, what is fifth generation aircraft? UAV?

Yes, UAV is the real standard of the fifth generation aircraft, but the era of UAV needs the rapid development of intelligent system. In this regard, it still needs five to ten years of technology accumulation, and the new generation of sixth generation aircraft should belong to aerospace fighters.

"In addition to the materials, the most important thing is the engine." hearing what song said, Lu also joined the discussion. What a powerful engine is needed to become an aerospace fighter?

According to the parallel space-time project, the X-37 developed by Yingguo can only be said to be the prototype of an aerospace fighter. It is an unmanned and reusable space aircraft developed by Boeing. This aircraft is about 8.8 meters long, with a wingspan of about 4.6 meters and a takeoff weight of more than 5 tons.

However, it can only be called a prototype, because this space plane does not enter space by its own power. It is only launched into space by rocket, and then glides back to the ground with solar cells. Its innovation is that it can fly on the earth satellite orbit and enter the atmosphere, and its maximum speed can reach more than 25 times the speed of sound After the mission, you can land on the runway of the air force base.

It's not easy to use your own power to go into space.

"President Qin mentioned before that after the successful development of our turbofan in the tenth five-year plan, the next generation is the variable cycle engine. Only this engine can become the power of our aerospace aircraft." old song said: "Even so, in order to reduce the difficulty, our most likely solution is not to take off directly from the runway, but to carry it on a supersonic plane, such as a transport plane that can fly at Mach 3, start it directly, that is, the ramjet engine, and then enter space orbit."

Listening to Lu Lao's smacking tongue for a while, "in this case, if you want to study aerospace fighters, you have to build a Mach 3 transport plane first?"

Qin Guan nodded. If the research and development of aerospace aircraft may be successful, only such a scheme now can be a truly operable scheme.

In fact, the space plane is not science fiction. It was popular all over the world as early as six or seven years ago. With the continuous development of the Star Wars plan, all countries are full of enthusiasm for going to the sky. The space plane scheme is the most appropriate way to quickly and low cost.

For example, Yingguo proposed to develop a fully reusable single-stage horizontal take-off and landing "National Aerospace shuttle" code named X-30, using a combined supersonic combustion ramjet engine. NiuGuo proposed a single-stage horizontal take-off and landing aerospace aircraft called "hotor", using a brand-new air liquefaction cycle engine. Hansguo proposed a two-stage horizontal take-off and landing Aerospace aircraft Sanger, the first stage is actually equivalent to a supersonic transport aircraft, and the second stage is a winged aircraft powered by a rocket engine. Both stages can land horizontally.

However, with the passage of time, they found that most of the schemes were very difficult and it was not so easy to conquer space. Later, the schemes gradually evolved and eventually became the last scheme. The aircraft was hunched over, giving the aerospace aircraft a speed and altitude first, and then launched.

The development of the space shuttle, like the original intention of the space shuttle, is to reduce the cost. After all, it can make full use of the oxygen in the atmosphere to reduce the oxidant carried by the aircraft, which can reduce the take-off weight. At the same time, the whole aircraft is reused, and the cost is lower. Finally, it takes off and lands horizontally, simplifying the operation procedures of the whole mission.

However, the technical difficulty was too great. Finally, they gave up.

Now, Mr. Song has aimed at this plan. If it can succeed, it is equivalent to a fighter revolution! This span can be said to be a leap forward development from propeller aircraft to jet aircraft. Although all countries began to give up, Mr. Song wanted to build this kind of aircraft.

If I can't figure it out, there will be the next generation of scientific researchers. In short, this project must be established first. I'm a pioneer. I'll explore the way first!

"In this case, we need to invest a lot of money," said Lu. "I'm afraid it's higher than all the money we have ever invested."

With the replacement of fighters, the research and development is becoming more and more difficult, and the cost is becoming higher and higher. Now, there are only two countries in the world that can develop the fourth generation aircraft, the Han country and the eagle country. The bear country is doomed to fail. I'm afraid there is only one country in the Han country that can develop the fifth generation aircraft!
