The difference of homebred C-919 old plane and American Boeing 777-300ER, be just like the distinction of Ao Di Q3 and Ao Di Q5, both the plane that is not a level.
Boeing 777-300ER belongs to double engine large wide body is long-range plane, basically serve line of Yu Zhongyuan Cheng, quantity carrying a passenger is in 300~500 person, its model seating achieves 386, can achieve 550 at most, airframe is 73.9 meters long, the ala exhibits 64.8 meters, farthermost be fully loaded with range to be able to amount to 15000 kilometers.
C919 belongs to the trunk plane of the one range in the paragraph, it is medium-sized narrow system plane, airframe is 38.9 meters long, the ala exhibits 35.8 meters, range is controlled in 5000 kilometers, carry a guest to measure 150 ~170, the commerce that future basically is executive home line holds guest job.
If want to compare the difference of C-919 and foreign plane, should be the same as level plane to just go quite then. The plane that Boeing is the same as level is Boeing 737MAX-8, empty guest be the same as level plane is empty guest A320neo. Contrast removes these two planes, c919 plane has a lot of advantages, because time of C919 research and development compares evening,this basically is, have definite late advantage.
For example the sailing of C919 plane is easy the gender will be much better, the fuselage cross section of C919 is larger, passenger seat is installed more greatly, comfortable sex also meets cockpit taller, these metropolises make flight experience of the passenger much better. In respect of boat cable system, of C919 boat report advocate the supplier is company of Er of Huo Ni Wei, this company also is Boeing of numerous plane fly to those who control a system advocate supplier. Had company of Er of American Huo Ni Wei escort the Emperor convoy, the advanced sex of system of C919 boat cable, dependability is beyond question.
In engine respect, what C919 uses is the LEAP-1C engine of CFM company research and development, the performance of engine is overall function is the LEAP-1B motor that place of plane of excel Boeing 737MAX uses, the LEAP-1C motor that uses with plane of empty guest A320neo is to be in same standard. And go up in composite material utilization rate, c919 plane wants than these two planes taller.
Because C919 plane still is in,show level test-fly, still do not have consign, because this cannot contrast deep further the problem such as fault rate, dependability. As a whole, c919 is mixed in the 737MAX plane that faces Boeing the A320neo of empty guest is to have stronger competition ability. Especially 3 person when using more adjacent motor, c919 will be depended on more the engine room design that human nature changes, taller economy will enhance competition ability.
Nevertheless, those who need a specification is, the A320neo plane of the 737MAX plane of Boeing and empty guest has belonged to mature type, its all sorts of time that improve model to need 9 years only can finish test-fly to obtain evidence and consign is used. And C919 is in plan respect is apparently backward, c919 is in ability head flew 2017, still be at present in nervous test-fly, had not obtained comfortable boat evidence. Obtain the comfortable boat evidence of civil aviaton total bureau of China besides the requirement, c919 future still needs obtain the comfortable boat card that American FAA and European EASA issue, ability marchs international market. In short, the development way of C919 plane future is not easy, still put in certain hard dangerous and difficult road, before continuity of Chinese aviation person tries hard, need goes.
Can say for certain, be in at present the C919 plane of test-fly is very advanced, what C919 plane goes is the way that globalization purchases, used the technical device of very advanced maturity on a lot of international, so its level can get assuring. Even if compare of the guest with level plane with Boeing, sky, c919 plane also is a bit does not fall lee.
