After that, Wang Bin also poked Professor and the others, and chatted for a while, and returned to this office about the construction of the aerial platform.
But shortly after Wang Bin returned to his office, Wang Bin received a call from Director Lu, the director of the industrial zone.
"Mr. Wang, this time your Tiangong Technology was really amazing in the air show! You actually got an order of 30 to 40 billion yuan. The people in charge of the county and the city, for this time your Tiangong Technology obtained I am very happy with the results. This time I really won my breath for our county and even the city! In the past, there was no aviation company in our county, and even the city only had one drone. It is only a production and R&D enterprise, and its products are tepid, and the orders received at each air show are basically very few! In the entire air show, it is often the bottom of the ranking.
But this time is different. You Tiangong Technology has become the most eye-catching star enterprise during the entire exhibition. Therefore, our city and county have great expectations for your Tiangong Technology, and hope that you Tiangong Technology Science and technology can become a leading high-tech enterprise in the city, make new contributions to the industrial development of our city, and make greater achievements for our country's aerospace industry. "Director Lu said happily on the phone.
"Don't worry! Tiangong Technology is an enterprise focusing on the development of aerospace and aviation, but for other developments, we will naturally not give up.
For example, the research and development of high-precision CNC machine tools that our Tiangong Technology has been involved in, and the research and development in the field of materials, etc. In addition, the research and development of our Tiangong Technology in network hardware and software is now also Starting formally, I think Tiangong Technology will never let everyone down! "Wang Bin said.
After chatting with Director Lu for a while, Wang Bin hung up the phone. Wang Bin naturally understood the attitude of the city and county officials. After all, Tiangong Technology was able to get such a big deal in this exhibition. The order for the city and the county is of great benefit, so the county and the city should naturally pay more attention to Tiangong Technology.
In Wang Bin's busy schedule, more than a month passed quickly. After many modifications and revisions, the components of the first prototype of a small bypass turbofan engine by Tiangong Technology were manufactured. And entered the final assembly stage.
Wang Bin is also very concerned about this small bypass ratio turbofan engine, because this engine is not only Wang Bin and Tiangong's first turbofan engine with small bypass ratio, but also because of this The thrust of the small bypass is up to 30 tons than the turbofan engine, and this engine will also be the super large aircraft being developed by Wang Bin, Tiangong Technology and Dai Lao, which is the best engine option for the Phoenix aircraft. One of the models.
After all, if under normal circumstances, a huge aircraft like the Phoenix basically does not use a turbofan engine with a small bypass ratio as its power, after all, under the same thrust, a large bypass is better than a turbofan engine. In terms of fuel consumption and stability, it is far better than a turbofan engine with a small bypass.
Yes, the large bypass ratio for the Phoenix aircraft that Wang Bin and the others are developing has a big defect, that is, the large bypass ratio engine cannot perform supersonic flight, and the size of the Phoenix aircraft is very large. It's huge, but it's a real supersonic plane.
So in terms of congenital conditions, this aircraft cannot use a large bypass ratio engine as the main power of the aircraft.
The two remaining options are to choose between a turbojet engine and a turbofan engine with a small bypass ratio.
However, both turbojet engines and small bypass ratio turbofan engines can be used as power for supersonic aircraft, but there are still obvious differences between the two.
Although the turbojet engine has many advantages, and even if the speed of the aircraft reaches Mach 2 or even Mach 3, the turbojet engine can still provide good power for the aircraft, but the turbojet engine also has obvious advantages. The defect of the engine is that the fuel consumption is much higher than that of the turbofan engine. In addition, in many other aspects, it cannot be compared with the turbofan engine.
The small bypass is different from the turbofan engine. Although the small bypass turbofan engine is not as good as the turbojet engine in terms of specific impulse, this makes the engine fan will be used when the aircraft reaches a certain speed, that is, when the speed of sound is more than 2 times the speed of sound. If a large wind resistance is produced, the probability of the engine will be significantly reduced, but the fuel consumption of the engine, the noise of the engine, and the thrust of the engine are better than the turbojet engine.
However, in comparison, in fact, whether it is Wang Bin or Professor Dai, etc., they are actually more inclined to small ducts than turbofan engines. After all, a giant like the Phoenix, even when it was designed, has already been Various factors have been considered ~www.mtlnovel.com~ including the wind resistance generated by the aircraft during flight.
But if you want its speed to reach more than twice the speed of sound, it's idiotic, and because the thrust of a turbojet engine is less than that of a turbofan engine, if you use a turbojet engine as the power of the Phoenix aircraft, it must be used for a long time. More engines.
At the same time, because the fuel consumption of the turbojet engine is much larger than that of the turbofan, it means that the aircraft must fly farther and must carry more fuel, which will greatly reduce the aircraft. Load capacity.
However, Wang Bin, Professor Dai and others did not completely give up the use of turbojet engines as power, because if turbojet engines are used as power, although there are many defects, if turbojet engines are used as power, they will be used as airplanes. The strength is sufficient. At high altitude, it is not impossible to exceed the speed of Mach two.
It is even possible to reach the double triple standard or higher. If the speed and altitude of the Phoenix aircraft can reach the double triple standard or higher, this will definitely help Tiangong Technology's aerospace industry. The Phoenix aircraft can be changed into an aerospace aircraft in the future, laying the foundation.
Of course, with the current capabilities of Tiangong Technology, it is basically impossible for the Phoenix to use turbojet engines as power and break the double triple standard, and turbojet engines with a thrust of more than 20 tons are not so good. R & D.
Therefore, under the current circumstances, Wang Bin and the others are still honestly using a small bypass rather than a turbofan engine. It is more appropriate to manufacture the Phoenix aircraft first.
After all, if the Phoenix fighter cannot be built, no matter how advanced the engine is, it will have no effect at all.
