It's shocking! Miller said excitedly again: "The M29 jet is truly an epoch-making aircraft that leads the trend of the aviation industry!" May I ask Mr. Xiao Weiguo, does it have a name? ”

Xiao Weiguo laughed and said: "I think everyone can call it the flying leopard, because it is very fast, and everyone knows that the cheetah is the fastest animal on land." Our M29 jet, it's the fastest flying aircraft in the sky, so it's called the Flying Leopard, or you can call it the Flying Leopard! ”

At this time, the surrounding talents reacted, and when they heard Xiao Weiguo's name for the M29 jet, everyone applauded, and the applause rang out enthusiastically.

In addition to Xiao Wei, Karl and Messerschmidt and others were also surrounded, and they really couldn't get out without answering some questions. Finally, several talents broke out of the siege and came to the lounge prepared by the organizing committee for each team.

Xiao Weiguo said with a smile: "Everyone has worked hard, these people are really too enthusiastic, and the enthusiasm is so fast that people can't stand it." However, our M29 jet today was an eye-catcher, and I think everyone in the room was crazy about it. ”

Messerschmitt nodded and said, "Yes, especially those aircraft manufacturers, will definitely come to the door, I think as long as you are engaged in aircraft design and manufacturing, there is no one who does not want to get jet technology." In this way, we can sell the Thunder jet engine. It's just that if someone pays a premium for our jet engine technology, then do we sell it or not? ”

Carl laughed and said, "I think it's definitely better to sell products than to sell technology!" No matter how high the price is offered. If you sell the technology, it's not a slip of the road. I believe that for at least a decade, no company will be able to produce a jet engine similar to the Thunder turbojet. Even if someone comes up with a turbojet engine, it will certainly not be comparable to us in terms of technological maturity. So we are exclusive and have absolute control over the price of the engine. And if another manufacturer buys our technology and produces the same jet engine, then the competition will definitely intensify, and our profits will drop significantly. ”

Xiao Weiguo stroked his palms and smiled: "Carl is right, our jet engine technology must not be sold." If you want to sell, you can't sell until five or ten years later. I want to control the entire world market in the field of the aviation industry with the Thunder jet engine and the Thunderbolt turboprop engine. Without our Thunder jet engines and Thunderbolt turboprop engines, it would be impossible for those aircraft manufacturers to survive the competition, let alone grow. It is impossible for us to take all the market share of aircraft manufacturing. But we can occupy the high-tech jet engine market. In addition, I have an updated plan, which is to use the profits from the Thunder jet engine and the Thunderbolt turboprop engine to design and develop two more advanced aero engines. That's the turbofan engine and the turboshaft engine. And it is powered by these two new engines. Design and development of new aircraft, helicopters and advanced turbofan aircraft. ”

As soon as Xiao Weiguo's voice fell, the entire lounge became extremely quiet, and everyone was shocked! Xiao Weiguo always surprises people. Turboshaft engines and turbofan engines? And what is a helicopter? Even Messerschmidt, as an aviation expert, only knows about helicopters, and not about turboshaft engines and turbofan engines! No one else had heard of it.

After a while, Karl said, "Why have I never heard of it?" What exactly do these engines and planes look like? ”

Xiao Weiguo said with a smile: "It's normal that you haven't heard of it, because I figured out these new things." No one in the world has studied it yet, so it would be strange if you had heard of it. Probably only helicopters. Someone studied. The turboshaft engine I designed was mainly used to power the helicopter. The principle is actually similar to that of a turboprop engine. After the core engine or gas generator, a set of turbines is installed, which can be one or more stages, the gas expands in this latter power turbine, drives it to rotate at high speed and emits a certain power, the front axle of the power turbine passes through the rotor of the core engine, and the output shaft outputs power after deceleration through the reducer in front of the compressor, which is mainly used for helicopter power. ”

"In the turboshaft engine, the available energy generated by the gas generator is basically absorbed by the power turbine and output from the power shaft, and the rotor and tail rotor of the helicopter are driven by the final drive on the helicopter after deceleration; The temperature and velocity of the gas ejected from the tail nozzle are extremely low and essentially no thrust is generated. This is the biggest difference between it and turboprop engines, because the gas emitted from the nozzles of turboprop engines also has a certain amount of thrust. Xiao Weiguo said calmly.

Messerschmidt said excitedly: "Ah, so the biggest problem of the helicopter is solved?" Helicopters are a promising flying vehicle, but they have not been truly successful due to lack of power and flight control problems. If the powerful turboshaft engine is used in the helicopter, it can perfectly solve the power problem of the helicopter. ”

Bai Wanrou was confused when she heard this, and she said curiously: "What does this helicopter look like?" Is it that good? ”

Xiao Weiguo smiled and said, "Wanrou, speaking of which, the helicopter is the prototype of your Chinese invention!" You must have played with a toy called a bamboo dragonfly when you were a kid, right? This is a magical invention of the Chinese, about 400 BC, in China there was a bamboo dragonfly. Although the helicopter we are talking about is ten million times more complex than the bamboo dragonfly, the flight principle of the two is similar. The rotor used in the helicopter is like the blade of a bamboo dragonfly, the axis of the rotor is like the thin bamboo stick of the bamboo dragonfly, and the engine that drives the rotor is like our hand rubbing the bamboo stick vigorously. The blades of the bamboo dragonfly are round and blunt in front and sharp in the back, with a rounded arch upper surface and a straight lower surface. When it rotates, a pressure difference is formed, creating an upward lift. When the lift force is greater than its own weight, it will take off into the air. As early as 1907, the French made a helicopter called a flying bicycle, but it could only be 0 off the ground. 3 meters, it cannot yet be called a real helicopter. Later, it was not until 1930 that the United States developed a helicopter, but because of the use of piston engines, the engine power was insufficient, and it could not be put into practical use.
