C919The passenger aircraft is a medium to short distance commercial aircraft with an actual total length38Meter, wingspan35.8Meter, height12Mi, its basic layout is168Seat. The standard voyage is4075Kilometers, with a maximum range of5555Kilometers, with an economic lifespan of9Ten thousand flight hours. In terms of material usage,C919A large amount of advanced composite materials, advanced aluminum lithium alloys, etc. will be used, among which the usage of composite materials will reach20%Through the detailed design of the internal structure of the aircraft, the weight of the aircraft is compressed downwards. At the same time, due to the extensive use of composite materials, compared to similar foreign aircraft80Decibel cabin noise,C919The noise inside the cabin is expected to decrease to60Below decibels. Besides,C919Will use the weight of the entire machine structure20-30%The domestically produced aluminum alloy, titanium alloy, steel and other materials fully reflectC919The ability and future trends of large passenger aircraft to drive domestic basic industries.
