At the same time, on the new R & D project, Wang Bin immediately discussed with Professor poke after he came back. After all, the thrust of the new engine should be at least 18 tons, and it is also a turbofan engine of more than four generations. Professor poke should also think about how to design it.


    At the same time, Wang Bin''s tg-002 engine was finally successful. However, Wang Bin was somewhat depressed to find that this engine did not seem to be of great use except installed on high-speed high-altitude fighter planes such as No. 7 and No. 8. After all, aircraft such as No. 10 and No. 11 used turbofan engines with small bypass ratio, No turbojet engine at all.


    Although the turbojet engine can provide aircraft with greater altitude and speed, for aircraft such as No. 10 and No. 11, its own body can not bear the speed of more than 30000 meters at Mach 3. Even aircraft such as No. 7 and No. 8 are only available after transformation, The performance of this engine can''t be brought into play at all.


    Not to mention, the thrust of tg-002 engine has stronger thrust and effective flight altitude and speed than that of TG-001 turbojet engine. Therefore, unless a high-altitude and high-speed aircraft is redesigned, there is really no good use like tg-002 turbojet engine.


    Thinking of this, Wang Bin immediately told Professor poke what he thought, and Professor poke had no good way for a while.


    So Wang Bin and others handed over Professor Dai and Professor Zhang and asked their opinions, but obviously, like Wang Bin and Professor Zhang, they have no good way. After all, there are only a few domestic aircraft, and the aircraft that can fly at high altitude and high speed are only old models, Therefore, if they want to give full play to the performance of tg-002 turbojet engine developed by Tiangong technology, they can only develop a more advanced high-altitude high-speed aircraft.


    "Professor Dai! Is there really no other way? You know, it is very difficult to develop a high-altitude and high-speed aircraft, and the requirements for materials are more stringent than the materials used by the main fighters in our country, so is it really feasible to develop a new high-altitude and high-speed aircraft?" Wang Bin asked suspiciously.


    "Mr. Wang! In fact, I have long had the idea of developing a new high-altitude high-speed aircraft. I have had this idea since the TG-001 turbojet engine of Tiangong technology was developed. After all, the aircraft in our country, including No. 7, No. 8 and the current main fighters, can not give full play to the full performance of our two turbojet engines.


    Most importantly, Mr. Wang, I remember you said that the ultimate goal of our Tiangong technology in the near future is to develop aerospace vehicles that can fly freely in space.


    If we really want to develop similar aircraft, we can''t get around the research on high-altitude and high-speed aircraft. Therefore, I think it''s time for us to start developing aircraft in this field, so as to lay a foundation for our Tiangong technology to develop aerospace aircraft in the future. "


    After listening to Professor Dai''s words, Wang Bin did not speak immediately. As Professor Dai said, the ultimate purpose of their Tiangong technology in aviation is indeed to develop an aerospace aircraft integrated with space. If they want to develop an aerospace aircraft, they can''t get around in the research and development of high-altitude and high-speed aircraft, and in the research and development of turbojet engine, We can''t stop research and development because this engine is not used for much at present.


    At the same time, in addition to the research and development of turbojet engine, the research and development of pulse engine must also be carried out. After all, even if the turbojet engine reaches a certain height, it will stop working because of the lack of oxygen inhalation. At this time, it needs pulse engine or ramjet engine to provide power.


    Of course, if the aircraft has flown to the edge of the atmosphere, neither ramjet nor pulse engine can work. At this time, only rocket engines and other engines specially used in vacuum environment can work.


    Therefore, as Professor Dai said, for the research and development of high-altitude and high-speed aircraft, their Tiangong technology must be carried out.


    So Wang Bin nodded and then asked him, "Professor Dai, although for high-altitude and high-speed aircraft, Tiangong technology must carry out research and development, even if it is just a verification machine.


    But you see, what type of high-altitude and high-speed aircraft should we develop? High-altitude and high-speed fighter aircraft such as No. 7 and No. 8, or high-altitude and high-speed reconnaissance aircraft like other countries, or simply develop larger high-altitude and high-speed bombers and aircraft or transport aircraft? "


    After hearing Wang Bin''s inquiry, both professor poke and Professor Dai fell into meditation, because both professor poke and Professor Dai have not seriously considered this problem, but now they have no choice but to ask this question, so they naturally have to think about it.


    After coming for a while, Professor Dai looked up and said to Wang Bin: "Mr. Wang! I think if we continue to develop high-altitude and high-speed fighter and reconnaissance aircraft, it will not be of great significance to our company and China now. Therefore, I think I should develop heavy aircraft in high-altitude and high-speed. The best aircraft can have a tonnage of more than 100 tons, and this aircraft should also have a very strong carrying capacity, whether it is Whether it''s carrying cargo, bombs or people.


    After all, our research and development of this aircraft has been very clear, that is to lay a good foundation for the future research and development of aerospace aircraft. However, what is the purpose of our research and development of aerospace aircraft? It is to transport personnel and various goods from the ground to space and reduce costs on a large scale.


    Therefore, since this aircraft is to lay the foundation for the future research and development of aerospace aircraft, there is only one choice for us, that is, to develop large aircraft with high-altitude and high-speed flight capability. "


    Wang Bin nodded at Professor Dai''s words. After all, Professor Dai has made it very clear that there is only one option for Tiangong technology. However, Wang Bin immediately thought that if we can really develop large aircraft with high-altitude and high-speed flight capability, it is not a bad thing, not to mention who says that large aircraft have no combat and investigation capability, Carrying air-to-air missiles for high-altitude and high-speed operations is also a large high-altitude and high-speed aircraft, which can also carry out air operations.


    Most importantly, large high-altitude high-speed aircraft can not only be used as a platform for investigation and prediction, but also as a bomber. At the same time, if possible, coupled with the ability of stealth, it is absolutely of great significance for research and development.
