Chapter 1468 Airworthiness Certificate of Passenger Aircraft

So Jiang Chen also hopes that through his own efforts, he can save some face in this regard and show the world our efforts and achievements in the aviation industry.Furthermore, this is also an official promotion meeting or promotion meeting.Jiang Chen wanted to take advantage of the opportunity to get more orders, so he could take advantage of it.

After looking around, Jiang Chen and the others walked out of the cabin, looking at the huge monster in front of them, Jiang Chen felt a lot of emotion.He didn't expect that through his hard work, he could actually get this big guy out.Through his efforts, our aviation industry has been passed on from generation to generation, and will not be broken, so that it can be reborn from the ashes.In his opinion, although these achievements are one aspect, what he values ​​more is the growth of this team.Especially the joining of those young people, let us have successors in the aviation industry, this is where he feels the most fulfilled.

Seeing Jiang Chen's dazed look, Elder Du smiled at Jiang Chen and said, "Xiao Jiang, how are you?"

Jiang Chen gave everyone a thumbs up and said, "It's very good. If I had known it was so good, I should have brought an extra car when I came here. Now in front of such great results, I feel that I have brought The ones that came are a little out of hand.”

"Hahahaha,,," everyone present burst into laughter.Elder Du laughed and scolded: "Go, make it seem like we care about your little fruit."

"Hehehehe," Jiang Chen also laughed.After a burst of laughter, Jiang Chen looked at the yellow-skinned airliner lined up next to him, so he said with a smile, "Old Cui, what's the situation with that airliner over there."

"I'm interested, let's go and have a look." Cui Lao said with a smile.Immediately, Jiang Chen and the others came to the front of the passenger plane.

Coming to the passenger plane, Jiang Chen couldn't help but looked it over carefully.Compared with the transport plane, the appearance of this passenger plane has changed a lot. In addition to the lengthened body, there are also big differences in the structure and layout of the plane.For example, the transport aircraft adopts a wide-body fuselage design, which is also for the convenience of transporting goods.And this airliner has shrunk in width, but lengthened in length, in short, it is more in line with the streamlined design.

Compared with the upper monoplane used by transport aircraft, this passenger aircraft uses a lower monoplane, which is one of the most obvious differences between transport aircraft and passenger aircraft.The reason for this is that military transport aircraft mainly transport heavy cargo, and the use of the upper monoplane is conducive to the control of the center of gravity of the aircraft.Moreover, the upper monoplane layout has low interference resistance, has a good downward view, and the fuselage is close to the ground, which is convenient for cargo loading and transportation.In addition, military transport aircraft are adapted to a special environment, and they often take off and land on some loaded roads.Therefore, the use of the upper monoplane can make the engine higher off the ground and avoid the damage of sand and stones flying from the ground.Therefore, most of the military transport aircraft and propeller transport aircraft in the world currently adopt this layout.

The airliner adopts the lower monoplane, mainly because the lower monoplane also has its huge advantages, especially for civil aviation airliners.First of all, the lower monoplane helps to shield the engine noise and improve comfort, and secondly, the lower monoplane has better take-off and landing performance.Another thing is that the engine position of the lower wing is low, which is convenient for maintenance, and the lower wing is also easy to arrange the position of the landing gear.In addition, the mechanical structure of the lower wing is relatively simple, and the spar is under the floor, which is convenient for planning the layout of the away field.Compared with the T-shaped tail used by transport aircraft, the tail of passenger aircraft is relatively common, and the conventional tail used by most passenger aircraft is chosen.This is also done to further enhance the stability of the aircraft.

Seeing Jiang Chen's serious look, Mr. Cui smiled and said, "This is the airliner model we developed based on the unified platform. Although in terms of appearance, there are big differences based on your internal results and functions. , but they are all similar in terms of technology. And our change is also to hope that this civil aviation airliner can better adapt to the needs of aviation flight. The normal passenger capacity of this airliner is 95 people. Under the layout of all economy class, its The maximum passenger capacity can reach 110. In order to lighten the structure of the fuselage, and to be more economical and environmentally friendly, we use a lot of aviation aluminum on the fuselage. In addition, we use carbon fiber materials in many parts, which greatly reduces the In this way, the flight range of the aircraft can reach [-] kilometers, which can fully meet the needs of domestic and regional regional airliners.

We strictly refer to European and American flight test standards for the design and development standards of the entire aircraft.On the one hand, it is to improve the safety performance of the aircraft, and on the other hand, it is also to enter the international market in the next step.It can be said that in terms of current similar passenger aircraft, our technical level should be said to be in the leading ranks. "

Hearing this European and American standard, Jiang Chen's joyful mood suddenly became dignified.Compared with transport aircraft, passenger aircraft need to obtain an airworthiness certificate issued by the air traffic control department before being put into commercial operation, that is, a trial flight permit.Only after getting this can it be put into the market later.

As for the airworthiness certificate of this kind of aircraft, there are mainly three in the world which are the most important.They are the airworthiness certificate of the Old American Aviation Administration (FAA), the airworthiness certificate of the European Aviation Safety Agency (EASA), and the airworthiness certificate issued by our domestic air traffic management bureau.However, our relevant certification system is relatively backward, but it is also very useful.

The airworthiness certificates of these three regions represent the three regions respectively. First of all, if our domestic airworthiness certificates are obtained, they can be applied not only in China, but even in the entire Asian region.Not only in Asia, but also in Africa and South America.This is mainly because there are very limited countries and institutions in the world that have the ability to formulate such sea trial standards and issue airworthiness certificates.Moreover, the threshold is relatively high, and it is not something that some small countries can play, and it is not authoritative.

However, our airworthiness certificates are not applicable in Europe and North America. If you want to enter the markets of these two regions, or even fly in these two regions, you cannot obtain the airworthiness certificates of these two places.But these two airworthiness certificates are not so easy to obtain.We must know that those aviation manufacturing giants promoted the formulation of this airworthiness certificate at that time, so it also has a certain degree of exclusion.As for these two places, one is the old nest of Boeing, and the other is the old nest of Airbus.How difficult it is to get an airworthiness certificate on their turf.
