The hangar is used as a place for aircraft parking, which has many types of hangars, starting from the most basic open-air hangar, then ordinary closed hangars, and then there are various special hangars with special requirements, underground bunker hangars, cave tunnel hangars; It is used for various special tests, such as the icing test hangar, as well as the modern enclosed hangar with constant temperature and humidity.

Anyway, the small hangar also has a variety of designs, specific to the current front of the United Passenger Aircraft Company's hangar, compared with those tall special hangars are much simpler, parking large test aircraft hangars actually do not have much requirements, only need to be on the basis of the usual large hangar, and add some more basic test equipment that is convenient for scientific research and testing personnel, and make the internal area wider is enough.

The huge two rectangular left and right hangar doors are no longer ordinary manpower can be pushed open, only under the drive of the electric motor slowly slide along the guide rails to both sides, and the sunlight also spills into the interior of the hangar at the first time when the two doors are separated, part of it shines on the solid concrete floor, and more shines on the MPC-75 in the center of the hangar.

As the two doors continue to separate on both sides, more sunlight also spills into the hangar, and the front of the MPC-75 is also completely lifted its red head, the round, honest nose design makes the aircraft appear extraordinarily heavy, the design of the six windshields is also a decent scheme, although it is not very fashionable, but it is definitely the most mainstream jet airliner windshield design scheme at present, presumably this should be the chief engineer team directly moved the windshield design of Yun Shi!

Just as the group was attracted by this prototype, the on-site engineers who were originally working in the hangar were also looking for sunshine. Finally, Yang Hui and his party fixed their eyes on the gate. I closed my eyes slightly, feeling used to the harsh light of the noon. I put down some of my work for the time being.

The first to run over was: "Our general manager Yang has arrived, why don't you come and take a look." This is the MPC-75 large regional airliner that we have developed over the course of five years, and it is definitely the most advanced regional airliner in the world, and there is no one! ”

Tang Changhong was also the first to start speaking, he was able to participate in this project at a young age, and served as the deputy chief designer, as a young man, he must be the first to rush to the front line to participate in various projects, but at this time, relying on the young man's good skills, Lin Bo Weibu first floated to Yang Hui's side.

At this time, there was no need to say any more flattering words, only a slow motion with his left hand and right hand. With a rich facial expression "pop, pop, pop"

With the can't help but applaud, and there is a trend of more and more people joining in, this laughed loudly again: "Okay! Good! It's really good, we have been concentrating for five years, after investing a lot of money, we finally saw it from the drawing into the real thing, we from the static test stage to the current first flight, this is a victory, is a witness to the friendship between the Chinese and German peoples! ”

At the time of shouting praises to the MPC-75. Yang Hui will definitely not forget to give the Germans a sense of saving, after all, Yang Hui saw a lot of German technicians on the spot, the research and development of the aircraft was originally jointly developed by the two countries, and the entire research and development, prototype manufacturing, and testing work was carried out in the Republic. Naturally, the Germans will also appear here.

Sure enough, after Yang Hui shouted long live the Sino-German friendship and highly affirmed the MPC-75 project. The Germans couldn't help but run over, and at first they were still speaking in half-baked Chinese. Later, I found that the meaning was not very precise, and I found that it was not very clear in Chinese. This was changed to a German grunt with gestures

"Of course, our cooperation is fruitful and has a bright future, the MPC-75 is an absolutely excellent aircraft, and I also believe that the cooperation between us is definitely not limited to here, this aircraft, with the completion of the MPC-75 project, I believe that there will be more cooperation space, we are just a small step of friendship this time!"

Bragging about this kind of thing Yang Hui has long been familiar with and can no longer be familiar, the German just now wants to shout that there is a deeper future of cooperation between the two sides, Yang Hui must also cooperate, anyway, there is nothing credible to speak at this time, it is all polite and routine!

Fortunately, the Germans didn't pester Yang Hui to be standing here chatting and farting, a group of people quickly walked into the inside of the hangar, since they all saw the real body of the plane, then they must have a sneak peek of the overall design to solve the doubts in their hearts.

After walking around the plane, Yang Hui's first impression was that this guy's cabin door was really not ordinary, as far as this aircraft was originally designed as a 75-seat aircraft, it was able to install three passenger boarding doors, not counting emergency escape, service doors and the like, how much is this

"As for the 75 passengers carried in the design of this aircraft, I won't talk about the rest, but there are a lot of cabin door designs, and if you use a mobile passenger aircraft boarding car with a remote position, the time for passengers to get on and off the plane should be very fast, right?"

Walking in front, Chief Master Ma answered this question without thinking about it, the design of this hatch is very exquisite, and now it seems that there are more designs, but when the aircraft is improved later, then its subtleties can be seen.

"Do we have a lot of hatch designs? This is not necessarily, just our current design scheme, the basic number of passengers of the entire aircraft has reached 82 people, this is still considered two rows of business class seats, and the design scheme after the emergency escape door in the middle of the wing is completely vacated, if we do not consider business class, compress the distance between the front and rear seats to adopt a high-density scheme, even if the current fuselage design does not make any changes, it can also achieve a maximum of 104 seats layout. ”

Hearing this, Yang Hui couldn't stop sweating in his heart, just now this kind of body design can be arranged into a 104-seat scheme, is this loading sardines or what? Thinking of this, Yang Hui was no longer surprised that the design team increased the conventional layout plan from 75 to 82 seats, because these guys were probably going for a 100-seat passenger plane from the beginning.

Fortunately, Yang Hui is still relatively sober now, knowing that these 104 seats are not very reliable, and it is absolutely impossible for civil airliners not to have business seats: "104 seats? There should be very few such layouts, and it seems that no airline will adopt all high-density cockpit layouts, so if we want to increase the passenger capacity, we should continue to increase the length of the airframe. ”

Inadvertently, Yang Hui also revealed the idea of elongating the MPC-75 passenger aircraft, which made Tang Changhong grasp the key point at the first time, he has been thinking about the elongation of the MPC-75 passenger plane for a long time, in his opinion, it is also a 3+2 seat arrangement, and McDonnell Douglas can achieve a regular passenger capacity of more than 130 people, why can't we.

"Yes, the MPC-75 has the potential to be elongated and transformed into a trunk airliner, and it is not a problem to achieve a passenger capacity of 130 people in an ordinary cockpit layout, which does not have any technical problems in the design of the aircraft, the only thing to note is that the thrust of the CG-2000 engine is definitely not able to meet the requirements, and we still need to improve the CG-2000 engine."

Improving the CG-2000 engine? This is a point that must be considered, there was an idea of the serial development of the CG-2000 engine, and now it seems that it is necessary to carry out the design of the engine first! (To be continued.) )
