Afterwards, Wang Bin also posted on Professor and others, and talked for a while, and returned to this office about the construction of high-altitude platforms.

However, 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, you Tiangong Technology is amazing in the air show! You actually got an order of 30 to 40 billion yuan. The heads of the county and the city are very happy about the achievements you Tiangong Technology have achieved this time. This time I really won a sigh of relief for our county and even the city! In the past, since there was no aviation company in our county, and even the city had only one drone production and R&D company, and its products were lukewarm. The orders obtained at each air show were basically very few! In the entire air show, they were often ranked last.

But this time it was different. Your Tiangong Technology has become the most eye-catching star enterprise during the entire exhibition period. Therefore, our city and county have great expectations for your Tiangong Technology. We also hope that your Tiangong Technology can become a leading enterprise in the city's high-tech field, 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! Our Tiangong Technology is a company that focuses on the development of aerospace, but we, Tiangong Technology, will naturally not give up on other aspects of development.

For example, our Tiangong Technology has already involved the research and development of high-precision CNC machine tools, and other aspects of materials, etc. In addition, our Tiangong Technology's research and development of network hardware and software has officially begun. I think our Tiangong Technology will definitely not disappoint everyone!" 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 large order at this exhibition, which is of great benefit to the city and county, so the county and city naturally should pay more attention to Tiangong Technology.

...........

With Wang Bin's busy schedule, more than a month passed quickly. After many modifications and modifications, the components of the first small bypass ratio turbofan engine prototype of their Tiangong Technology were manufactured and entered the final assembly stage.

Wang Bin is also very concerned about this small bypass turbofan engine, because this engine is not only the first small bypass turbofan engine of Tiangong Technology with small bypass turbofan engine, but also the thrust of this small bypass turbofan engine reaches 30 tons, and this engine will also be the super-large aircraft developed by the Tailor Dai of Tiangong Technology, which is one of the best engine alternative models for the Phoenix aircraft.

After all, if it is normal, a large aircraft like the Phoenix basically does not use a small bypass turbofan engine as power. After all, under the same thrust, the fuel consumption and stability of a large bypass turbofan engine is far better than a small bypass turbofan engine.

All, the large bypass ratio has a great flaw for the Phoenix aircraft that Wang Bin and others are developing, that is, the large bypass ratio engine cannot perform supersonic flights. Although the size of the Phoenix aircraft is very large, it is a real supersonic aircraft.

Therefore, in terms of innate conditions, this aircraft cannot use a large bypass engine as the main power of the aircraft.

The remaining two options are to choose between a turbojet engine and a small bypass ratio turbofan engine.

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 turbojet engines have many advantages, and even if the speed of the aircraft reaches a speed of two Mach or even three Mach, the turbojet engine can still provide power to the aircraft well, but turbojet engines also have obvious shortcomings, that is, fuel consumption is far higher than that of turbofan engines. In addition, in many other aspects, it cannot be compared with turbofan engines.

Small bypass ratio turbofan engines are different. Although small bypass ratio turbofan engines are not as good as turbojet engines in terms of specific impulse, this makes the engine fan produce a lot of wind resistance after the aircraft reaches a certain speed, that is, at a speed of twice the speed of sound, and the probability of the engine will drop significantly, but the engine fuel consumption, engine noise, and engine thrust are better than turbojet engines.

However, in comparison, whether it is Wang Bin or Professor Dai, they actually prefer small bypass turbofan engines. After all, even when designing, a giant like the Phoenix has already considered various factors, including the wind resistance caused by the plane when flying.

However, if you want to make its speed reach more than twice the speed of sound, it is simply a fool. Since the thrust of the turbojet engine is less than that of the turbofan engine, if you use the turbojet engine as the power of the Phoenix aircraft, more engines must be used for a long time.

At the same time, since the fuel consumption of turbojet engines is much larger than that of turbofans, it means that if the aircraft wants to fly further, it must carry more fuel, which will greatly reduce the load capacity of the aircraft.

However, Wang Bin, Professor Dai and others did not completely give up using turbojet engines as power, because although there are many shortcomings when using turbojet engines as power, if the turbojet engines as power, it is not impossible to use turbojet engines as power when the aircraft is strong enough and at high altitudes, it is not impossible to exceed Mach 2 speed.

Even if it reaches the double three standard or above, it is not impossible. If the speed and altitude of the Phoenix aircraft can really reach the double three standard or above, it will definitely be of great help to Tiangong Technology's aerospace industry, and it can even make the foundation for changing the Phoenix aircraft into a space plane in the future.

Of course, with Tiangong Technology's current capabilities, it is basically impossible to make Phoenix use turbojet engines as power and break the double three standard. And a turbojet engine with a thrust of more than 20 tons is not so easy to develop.

Therefore, under the current circumstances, Wang Bin and others are more suitable to honestly use small bypass than turbofan engines. Let’s first build the Phoenix aircraft.
