Chapter 907 (2/2)
”Internal dimension: the width of the main passenger compartment is 7.39m; The upper cabin width is 5.20m; Height (all) 8.50m; Floor down luggage compartment volume 126.4m * 3; The volume of main luggage compartment is 521.5m * 3; The volume of the upper luggage compartment is 198.1m * 3. ”
”The design range is 14500-15800 km, and the final value depends on what kind of engine black cloud can provide.”
”Md-12 requires the thrust of the power plant to be 1100 kn, that is, four engines with a single thrust of at least 267 kn are required.”
Baozixuan was fascinated. William Wales Douglas continued: ”the initial plan was to lengthen the md-10 aircraft that has been put into use, still use three engines, and the three-level layout has a passenger capacity of 375 people. Last time, little MacDonald gave some of your opinions and considered each seat: the direct use cost of miles is higher. ”
”Only then did we revise the plan and replace the original three release bureaus with four. The plan is mainly extended to two models: 630 seats for four engines and 500 seats for two engines. ”
Hearing this, I'm combining some information from my previous life. Baozixuan has fully understood that Americans have many design concepts, which is really ahead of schedule.
If McDonnell Douglas had not been struggling and untimely early in the 1990s, the md-12 would have succeeded before the Airbus A380.
William Wales Douglas looked at baozixuan and glanced at the fuselage and said, ”the fuselage is an oval section. Most of the 63.4-meter-long fuselage is 7.4 meters wide and 8.5 meters high. The aircraft is equipped with upper and lower cabins, and the bottom is loaded with luggage and cargo. There are two conventional stairs connecting the upper and lower cabins, and the width of the stairs allows two passengers with luggage to pass in both directions. Passengers need to pass through the lower floor when getting on and off the plane. First class is in front of the stairs before going down the cabin. The rear of the front stairs and the upper cabin can be arranged as business class or economy class. ”
Although smaller than its later Airbus A380, it is also fully sufficient. In fact, according to baozixuan, Airbus A380 is a waste. Only a few airlines have purchased in the future, and they are often not full.
The super rich have special planes, and people with poor economic conditions will choose low-cost airlines. Therefore, it is normal that the Airbus A380 is not full. Now this size is very good.
Bao Zixuan: ”there is no problem with the overall layout of the aircraft. At least I think it is feasible. In terms of aeroengines, heiyun will develop supporting products. In fact, using the existing engine can also meet the requirements, but we must do our best. We must surpass the Boeing 747 at all levels, otherwise the airlines will not pay. ”
”In addition, the avionics system, control system, flight efficiency system and communication system will be jointly developed by heiyun and Motorola. I believe there will be no problem combining the top talents of the two companies.”
”Mitsubishi will solve the problem of precision parts processing after the design is finalized. The four of us sit down and have a good communication. This plane must give people a different feeling, or I'm sorry for the efforts of the four enterprises. ”
Hearing that baozixuan was so understated, he solved all the problems and pointed out the country like an emperor. You know, this is McDonnell Douglas headquarters, and little MacDonald doesn't know how to describe it. But the mood at this time should not be very good. After all, he can't get in his mouth when the two technical giants chat.
This time, Bao Zixuan finished. William Wales Douglas said directly: ”this idea is very good. The aircraft involves hundreds of thousands of parts, including too many subsystems; We must find the most professional company to achieve the best results. ”
”McDonnell Douglas will complete the design as soon as possible and inform you three in advance when everything is ready.”
Knowing that it was superfluous here, little MacDonald left naturally. It's just that they can't talk about professional knowledge. Now old William wants to talk about cooperation. Since the old man is so interested, it's better not to disturb him.
In fact, sometimes we have to make some concessions, although McDonald merged Douglas. But the Douglas family still holds a lot of shares in the new company, and no one has so much cash to pay.
At McDonnell Douglas, people of the Douglas family still have a lot of weight. Under normal circumstances, little MacDonald will give each other face. Since it's redundant here, it's more comfortable to chat with beautiful women. With this in mind, little MacDonald went out to talk about life with the Dickinson sisters.
