After a few simple words of greeting, the two immediately became closer. This is the benefit of the alumni circle, and it is also the reason why so many famous Hollywood directors supported their alma mater after the scandal occurred at the University of Southern California.

Although William Wales Douglas was angry and even a little sad about the merger of Douglas Company by McDonnell Douglas, he had no complaints at all about MIT, the alma mater that trained him. And MIT was not only his alma mater, but also his alma mater.

The alma mater of his father, Donald Wales Douglas.

Bao Zixuan is known as the greatest graduate of MIT, and it is not without reason. His current achievements alone have surpassed those of the two founders of McDonnell Douglas and Douglas. As for how high he will develop in the future, only God knows.

Whoever has an aloof personality, Bao Zixuan personally came to visit you. Since they have not offended you, you must give them the face they deserve. Otherwise, not only will you be affected, but your company and family may also be affected.

Bao Zixuan smiled and said: "Senior, how far has the super-large passenger aircraft been designed? The research and development of the Heiyun engine has begun, and we will see the finished product within a year."

What does this guy mean? He is dissatisfied with the speed of his research and development. William Wales Douglas said very formally: "You are the one who said that there is no market for three-engine passenger aircraft. The future must be dominated by two-engine and four-engine aircraft."

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

The three-engine passenger plane was mainly due to his support. Of course, I would be dissatisfied when I heard someone wanted to build a four-engine super large passenger plane. Moreover, 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: "Everyone understands that the three-engine design has inherent shortcomings. Especially the engine arranged at the tail seriously affects the optimization of the aircraft's performance, so it is far inferior to the four-engine or two-engine layout. Because the three-engine aircraft

The power structure is unstable. The stability and balance of the power output at three points are far from

It is better to output symmetrically at two or four points. When encountering problems, accidents are more likely to occur. In addition, the engine has a certain weight. A three-engine aircraft must have an engine on the tail rudder, which will cause some

The problem of counterweight. In terms of fuel consumption, which is the most important factor for airlines, three engines are not as good as two engines."

"In fact, it's not just three-engine aircraft. As the thrust of aero-engines continues to increase, even four-engine aircraft, the dominant aircraft in the sky, will gradually withdraw from the stage of history."

Hearing that Bao Zixuan actually said that all four engines would be withdrawn from the stage of history, why should we continue to develop them? Little Macdonald wanted to say something, but looking at the posture of the two, he did not dare to speak.

It's okay to fool the beautiful models outside with my little aviation knowledge, but these two are top experts in aviation. Compared with them, I am at the level of a primary school student. I can't be embarrassed in front of experts, and since Bao Zixuan clearly knows the four

The development of super large passenger aircraft is about to be eliminated, but we are still sparing no effort in research and development. It is definitely not because there is too much money and no place to spend it, and I am not sure who will invest in this aspect.

In fact, William Wales Douglas is certainly aware of the disadvantages of three-engine aircraft, but he just doesn't want to be like Boeing. It may be due to vanity. Of course, it is not absolute. Three-engine aircraft can indeed save some fuel. But compared with the safety risks

, saving that little fuel will not attract customers at all.

I didn't expect the kid in front of me to be so determined, and this idea was not unreasonable. Who would have thought that airplanes could fly so fast and have such a long range 40 years ago. No one could have imagined the advancement of science and technology, and maybe this is really possible.

William Wales Douglas: "The future will be dominated by your young people. It seems that I am really old. I know that the four-engine super large passenger aircraft will be eliminated, but I still have to invest in research and development. It seems that this product is destined to be a transitional product.

You should have other ideas yourself!"

"In that case, I'll let you take a closer look. You are an expert in aviation. If you have any opinions, don't hide them. Only by discussing it together can technology progress and be responsible to users."

A drawing appeared in front of Bao Zixuan, and he was shocked after seeing it. Because the drawing reminded him of a name - the Airbus A380 double-decker passenger aircraft.

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

William Wales Douglas continued: "MD-12 super large passenger aircraft; overall dimensions; wingspan 64.92 meters; aircraft length 63.40 meters; aircraft height 22.55 meters; wing area 543.0 meters*2; main wheelbase 11.58 meters; front main

Wheelbase 26.82 meters.”

"Internal dimensions: main cabin width 7.39 meters; upper cabin width 5.20 meters; height (all) 8.50 meters; underfloor luggage compartment volume 126.4 meters*3; main luggage compartment volume 521.5 meters*3; upper luggage compartment volume 198.1 meters*3

.”

"The design range is 14,500-15,800 kilometers, and the final value depends on what kind of engines Heiyun can provide."

"The md-12 requires a thrust of the power unit of 1,100 kilonewtons, which means it requires four engines with a single thrust of at least 267 kilonewtons."

Bao Zixuan looked fascinated, and William Wales Douglas continued: "The original plan was to elongate the md-10 aircraft that has been put into use, still using 3 engines, and the three-level layout has a passenger capacity of 375 people. Last time

Macdonald Jr. give me some of your comments, also considering the higher direct cost of use per seat: mile."

"The plan has just been revised, replacing the original three-engine layout with four engines. The plan is mainly extended to two models: four-engine 630-seat aircraft and twin-engine 500-seat aircraft."

After hearing this and combining it with some information from previous lives, Bao Zixuan has completely understood that Americans have many design concepts that are really advanced.

If McDonnell Douglas had not been struggling and died prematurely in the 1990s, the md-12 would have likely succeeded before the Airbus A380.

William Wales Douglas saw that Bao Zixuan kept glancing at the fuselage and said: "The fuselage has an oval cross-section. Most of the cross-sections of the 63.4-meter-long fuselage are 7.4 meters wide and 8.5 meters high. The aircraft is equipped with

, there are two cabins below, and the bottom floor is for luggage and

Cargo. There are two conventional stairs connecting the upper and lower cabins. The width of the stairs allows two passengers with luggage to pass in both directions. Passengers must pass through the lower level to get on and off the plane. The first-class cabin is in front of the front stairs of the lower cabin. Behind the front stairs and the upper cabin

Can be configured as business class or economy class.”

Although it is smaller than the later Airbus A380, it is still sufficient. In fact, in Bao Zixuan's view, the Airbus A380 is a bit wasteful. Only a few airlines purchased it in later generations, and it was often not full.

The super rich all own private jets, and people with poor financial conditions will choose low-cost airlines. Therefore, it is normal for the Airbus A380 to be full of passengers, and the current size is very good.

Bao Zixuan: "There is no problem with the overall layout of the aircraft, at least I think it is feasible. As for the aero-engine, Heiyun will develop supporting products. In fact, the requirements can be met using existing engines, but we must do our best to do it."

It must surpass the Boeing 747 at all levels, otherwise airlines will not foot the bill."

"In addition, the avionics system, control system, flight performance system, and communication system will be jointly developed by Heiyun and Motorola. I believe that by combining the top talents of the two companies, there will be no problems."

"Mitsubishi will take care of the processing of precision parts. After the design is finalized, the four of us will sit down and have a good communication. This aircraft must give people a unique feeling, otherwise we will not be able to bear the sacrifices of the four companies."

Hearing that Bao Zixuan solved all the problems in such an understatement, he was like an emperor giving guidance. You must know that this is the headquarters of McDonnell Douglas. Little Macdonald didn't know how to describe it. But he shouldn't be in a good mood at this time.

, after all, when two technical experts were chatting, he basically couldn't get in the middle of the conversation.

This time it was even more extreme. After Bao Zixuan finished speaking, William Wales Douglas said directly: "This is a good idea. The aircraft involves hundreds of thousands of parts, including too many subsystems; you must find the most professional company to achieve the best results."

Best results.”

"McDonnell Douglas will complete the design as soon as possible and will notify you three in advance when everything is ready."

Knowing that being here was redundant, Little Macdonald left naturally. It was just that the two of them couldn't get in the middle of a conversation about professional knowledge. Now Old William also has to get involved in cooperation matters. Since the old man is so interested, it's better not to

It's better to bother.

In fact, some concessions had to be made at some point. Although McDonnell merged with Douglas, the Douglas family still held a lot of shares in the new company, and no one had that much cash to pay.

In McDonnell Douglas, the words of the Douglas family are still very important. Under normal circumstances, little Macdonald will give the other party enough respect. Since there is no need here, it is more comfortable to chat with the beautiful woman. With this idea, little Macdonald

Na went out to talk to the Dickinson sisters about life.
