Although the Rockets were launched continuously, and two of them were launched in the way of one arrow and multiple stars, which was very difficult to launch, Tiangong technology still completed the launch mission without danger.


    Why do you say that this launch mission is dangerous! This is because when the type 4 rocket, that is, when launching the deep space satellite developed and produced by Tiangong technology, when the rocket flew about 30000 meters away from the ground, one of the navigation systems of the rocket, that is, the navigation system subordinate to the civil fund, lost contact. 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 are military navigation systems.


    Therefore, after the civil navigation system of the rocket lost contact, the rocket immediately switched to the military version of the navigation system, and immediately conducted a self-test on the internal civil navigation system. However, according to the results of the self-test, it was found that there was no problem with the navigation system itself, but there was a problem with the signal, that is, the navigation system at this time was likely to be disturbed, According to the detection results, the signal interference came from space.


    Obviously, some people do not want Tiangong technology to develop so rapidly in aerospace. After all, with the development of Tiangong technology in aerospace technology, it has posed a threat to many people.


    However, even if some people do not want the successful launch of Tiangong technology, Tiangong technology has successfully completed the launch mission with its own strength.


    .....


    However, just when Wang Bin''s Tiangong technology successfully launched three rockets for three consecutive days, and successfully put all spacecraft into orbit, and the rocket itself was successfully recovered.


    Wang Bin received the 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 and successfully manufactured a pulse detonation engine with a thrust of 11 tons. Yes, a pulse detonation engine with a thrust of 11 tons.


    When Wang Bin heard the news, he immediately rushed to the rocket engine R & D 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 with more than ten tons of thrust developed by our laboratory. Of course, the ten tons of thrust here refers to the maximum static thrust, not the maximum thrust.


    In terms of maximum thrust, according to our calculation, under the condition 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 calculation. The real maximum thrust can only be known after the ultra-high speed wind tunnel test. "When Wang Bin came to the laboratory, the person in charge of the laboratory told Wang Bin.


    "Good! The static thrust reaches 10 tons and the maximum thrust is more than 35 tons. It is definitely a great engine, especially for the pulse detonation engine.


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


    Unfortunately, at present, except for some test aircraft, no aircraft in the world can withstand such a high speed, even if it is sprayed with high temperature resistant paint.


    However, fortunately, the aircraft that our Tiangong technology is trying to fly is also the phoenix-1 aircraft, but it can withstand such a large speed. After all, we have considered the ultra-high-speed flight in the design, and made sufficient optimization for the body and keel.


    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 high-temperature and high-strength special alloy, the middle layer is made of organic composite high-temperature resistant material, and the outer layer is covered by a layer of high-temperature ultra-thin special glass. Finally, there is a special high-temperature carbonization invisible coating, according to me According to our own tests, the skin of our aircraft can definitely withstand temperatures above 2700 degrees, and can also withstand temperatures above 3000 degrees in a short time.


    Therefore, even if the speed reaches Mach 6 in a short time, it is affordable for our phoenix-1 aircraft.


    However, compared with the huge fuselage of phoenix-1 aircraft, the thrust of the pulse detonation engine you developed is still insufficient. If your engine can reach the thrust of 18 to 20 tons, that''s good. "


    When talking about this, Wang Bin thought about it and said to them, "I will arrange the ultra-high speed wind tunnel test of this engine. However, although you have successfully designed a pulse detonation engine with a static thrust of more than 10 tons, in fact, this is only the beginning for your laboratory.


    So what you need to do next is how to increase the static thrust of your engine to more than 18 tons. At the same time, you should also find a way to combine this engine with the rocket engine to make it common for air and space flight.


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


    "Mr. Wang, don''t worry! We have been developing the pulse detonation engine integrating space and space, and we have some ideas. After all, the pulse detonation engine is different from ordinary turbojet and ramjet engines. During the transformation of space and space form, it is not as complex as other engines, and its specific impulse is definitely higher than that of ordinary engines It''s much bigger. "After Wang Bin finished, the person in charge said.


    Wang Bin is naturally very clear about the principle of converting the pulse detonation engine into a rocket engine. As long as the suction port of the pulse detonation engine is sealed, and then the fuel and oxygen are input, the engine can be converted into an excellent rocket engine and work normally. However, due to the high requirements for materials of the pulse detonation engine, Especially after being converted into a rocket engine, many people know the original, but they just can''t make it.


    Fortunately, Tiangong technology has a unique material technology in the world, especially in the field of high temperature resistant materials. After all, under the leadership of Professor Zhang, Tiangong technology materials laboratory has developed a variety of different high temperature resistant materials, among which the most excellent special ultra-high temperature resistant material, tantalum tungsten alloy, has the greatest practical high temperature resistance, It can already withstand the high temperature of about 35000 Baidu, and this material is very excellent in various properties. It can definitely be used as an engine high-temperature resistant material, so the material problem is absolutely no problem for Tiangong technology.
