Although the rockets were launched consecutively this time, and two of them were launched with multiple satellites in one rocket, the launch was very difficult, but Tiangong Technology still completed the launch mission perfectly without any risk.

Why do you say that this launch mission is a near miss! This is because, when the Type 4 rocket is launching the deep-space satellite developed and produced by Tiangong Technology itself, when the rocket flies to about 30,000 meters from the ground, one of the navigation systems of the rocket, that is, The navigation system belonging to the civilian version has lost contact, but fortunately, there is not only one navigation system in the rocket of Tiangong Technology. In addition to the civilian version of the navigation system, there is also a military version of the navigation system. .

Therefore, after the rocket's civilian navigation system lost contact, the rocket immediately switched to the military version of the navigation system, and immediately conducted a self-inspection of the internal civilian navigation system, but as a result of the self-inspection, it was found that the navigation system itself was not There is no problem, there is a problem with the signal, that is to say, the navigation system at this time is likely to be interfered, and according to the test results, the signal interference this time comes from space.

It is obvious that some people don't want Tiangong Technology to develop so rapidly in aerospace technology. After all, with the development of Tiangong Technology in aerospace technology, it has already caused a threat to many people.

But even if some people don't want Tiangong Technology's successful launch this time, Tiangong Technology has successfully completed the launch mission by virtue of its own strength.

.....

However, just when Wang Bin and his Tiangong Technology successfully launched three rockets in a row for three consecutive days, and successfully sent all the spacecraft into orbit, and the rocket itself was successfully recovered.

Wang Bin also received good news from the rocket engine laboratory of Tiangong Technology, that is, the pulse detonation engine of Tiangong Technology has finally made a qualitative breakthrough, successfully manufacturing a pulse detonation engine with a thrust of eleven tons The engine, yes, an eleven-ton thrust pulse detonation engine.

When Wang Bin heard the news, he immediately rushed to the rocket engine research and development laboratory, and saw the first pulse detonation engine with a thrust of 11 tons developed by this laboratory.

"Mr. Wang! This engine is a pulse detonation engine developed by our laboratory with a thrust of more than ten tons. Of course, the ten-ton thrust here refers to the maximum static thrust, not the maximum thrust.

In terms of maximum thrust, according to our calculations, in the case of high altitude and high speed, the thrust can reach more than 35 tons and less than 38 tons. Of course, this is only the result of our calculations. The real maximum thrust situation,

We still have to wait until the supersonic wind tunnel test to know. "When Wang Bin came to the laboratory the first time, the person in charge of the laboratory said to Wang Bin.

"Not bad! The static thrust reaches ten tons, and the maximum thrust is more than 35 tons. It is definitely a remarkable engine, especially for a pulse detonation engine.

It can be said that with the current situation of this engine, it has reached the practical stage, and due to the characteristics of the pulse detonation engine, if it is installed on an aircraft, it can definitely make the speed of the aircraft reach Mach 6 or more.

Unfortunately, at present, apart from some test-type aircraft, there is no aircraft that can withstand such a high speed, even if it is sprayed with high-temperature resistant paint, it cannot withstand it.

Fortunately, the aircraft that Tiangong Technology is testing is the Phoenix-1 aircraft, but it can withstand such a high speed. After all, when we designed it, we have already considered ultra-high-speed flight, and the airframe and keel Wait, enough optimizations have been done.

Even the skin of our Phoenix-1 aircraft is not an ordinary skin, but a multi-layer skin design. The inner layer of the skin is made of a special alloy with high temperature resistance and high strength, and the middle layer is Organic composite high-temperature-resistant materials are used, and the outer layer is covered by a layer of high-temperature-resistant ultra-thin special glass, and finally there is a special high-temperature-resistant carbonized invisible coating. According to our own tests, the skin of our aircraft can definitely withstand 2700 It can withstand temperatures above 3,000 degrees in a short period of time.

Therefore, even in a short period of time, reaching the speed of Mach 6 is acceptable for our Phoenix-1 aircraft.

However, compared to the somewhat bulky fuselage of the Phoenix-1 aircraft, the thrust of the pulse detonation engine you developed is still somewhat insufficient. If your engine has a static thrust of 18 to 2 Ten tons of thrust, that's fine. "

When talking about this, Wang Bin thought for a while and said to them: "I will arrange the supersonic wind tunnel test of this engine, but although you have successfully designed a pulse engine with a static thrust of more than ten tons Detonation engine, but in fact, for your laboratory, this is just the beginning.

So what you have to do next is how to increase the static thrust of your engine to more than 18 tons. At the same time, you also need to find a way to combine this engine with a rocket engine so that it can be used for space flight. the goal of.

After all, with the development of our Tiangong technology in aerospace, our need for aerospace vehicles is becoming more and more urgent, so I hope you can develop a usable aerospace vehicle engine as soon as possible. "

"Mr. Wang! Don't worry! We are already researching and developing the air-space integrated pulse detonation engine, and we already have certain ideas. After all, pulse detonation engines are different from ordinary turbojet and ramjet engines. When the sky shape is transformed, it is not as complicated as other engines, and after the transformation, its specific impulse is definitely much larger than that of ordinary engines." Just after Wang Bin finished speaking, the person in charge said.

As for the principle of converting a pulse detonation engine into a rocket engine, Wang Bin is naturally very clear. As long as the air inlet of the pulse detonation engine is sealed, and then input fuel and oxygen, the engine can be converted into an excellent rocket engine. It works normally, but because the pulse detonation engine has extremely high requirements for materials, especially after it is converted into a rocket engine, many people know the original, but it just cannot be manufactured.

Fortunately, Tiangong Technology has a world-leading material technology, especially in the field of high-temperature resistant materials. After all, Tiangong Technology Materials Laboratory, under the leadership of Professor Zhang, has developed a variety of different high-temperature resistant materials. Among them, the most outstanding special ultra-high-temperature resistant material, tantalum-tungsten alloy, has the maximum practical high-temperature resistance capacity, and can already withstand a high temperature of about 3,500 degrees, and this material is excellent in all aspects of performance. It can be used as a high-temperature resistant material for engines, so the material problem is definitely not a problem for Tiangong Technology.
