Chapter 907 (1/2)

With a few simple titles, they immediately narrowed the distance. This is the advantage of the alumni circle and the reason why so many famous Hollywood directors support their alma mater after the scandal in southern Canada.

William Wales Douglas was angry and even sad about the merger of Douglas company by McDonald. But there was no complaint about MIT, the alma mater that trained him. And MIT is not only his alma mater, but also his father Donald Wales Douglas's alma mater.

It is not unreasonable that baozixuan is known as the greatest graduate of MIT. Now alone, it has surpassed the founders of McDonald and Douglas. As for the height of the future, only God knows.

Who is lonely and arrogant? Baozixuan visits in person. People didn't offend you. You must give face. Otherwise, it will not only affect themselves, but also the company and family.

Bao Zixuan said with a smile, ”senior students, what is the degree of super large passenger plane design. The black cloud engine has started research and development, and the finished product will be seen within one year. ”

What does this guy mean? He's not satisfied with his R & D speed. William Wales Douglas said very formally, ”you said that there is no market for three engines, and there must be a world of two engines and four engines in the future.”

Why did you mention this again? It seems that the old man still can't let go.

The three engine airliner is mainly because of his support. Of course, I will be dissatisfied when I hear that someone wants to build a four engine super large airliner. And this person is not an ordinary layman, but a once-in-a-century super genius in the aviation industry.

Bao Zixuan said with a smile, ”we all understand. The three engine design is inherently deficient. Especially the engine arranged at the tail seriously affects the optimization of aircraft performance, so it is far inferior to the four engine or two engine layout. Because the power structure of the three engine aircraft is unstable. The stability and balance of power output at three points is far less than that of symmetrical output at two or four points. When you encounter problems, you are more prone to accidents. Also, the engine has a certain weight. The three engine aircraft must have an engine on the tail rudder, which will lead to some counterweight problems. In the fuel consumption that airlines attach most importance to, three engines are not as good as two engines. ”

”In fact, it's not just three engines. With the increasing thrust of the aeroengine. Even the four engine aircraft will gradually withdraw from the stage of history. ”

When I heard baozixuan say that all four engines are going to withdraw from the historical stage, how can I continue research and development. Little MacDonald wanted to say something, but looking at the posture of the two, he didn't dare to speak.

His little aviation knowledge fooled the beautiful models outside, but these two are top aviation experts. Compared with them, they are the level of primary school students. You can't make a fool of yourself in front of experts, and since baozixuan knows that the four engine super large passenger plane will be eliminated, he has spared no effort in research and development. Certainly not because there is too much money and no place to spend. No one will invest in this aspect.

In fact, William Wales Douglas knows the disadvantages of the three engine aircraft, but he doesn't want to be the same as Boeing. It may be that vanity. Of course, it's not absolute. Three engines can really save some fuel. However, compared with potential safety hazards, saving that little oil can not attract customers' favor at all.

I didn't expect the boy to be so determined in front of me, and this idea is not unreasonable. 40 years ago, who would have thought that planes could fly so fast and span so large. No one can predict the progress of science and technology. Maybe it is really possible.

William Wales Douglas: ”the future is really your young world. It seems that I am really old. Knowing that the four engine super large aircraft will be eliminated, we have to invest in R & D. It seems that this product is destined to be a transitional product. You should have other ideas! ”

”In that case, let you have a good look. You're an aviation expert. Don't hide your opinions. We can only make progress in technology and be responsible to users. ”

A drawing appeared in front of baozixuan. After reading it, he was very shocked. Because this drawing reminds him of a name - Airbus A380 double decker airliner.

In fact, Bao Shoufu had some misunderstandings, because before the Airbus A380. McDonnell Douglas also launched a double decker airliner, project code md-12, but it ended in failure.

William Wales Douglas continued: ”md-12 super large passenger plane; Overall dimensions; Wingspan 64.92m; 63.40m long; Machine height: 22.55m; Wing area 543.0m * 2; Main track 11.58m; The front main track width is 26.82m. ”
