“协和”是英法两国联合研制的四发远程喷气超音速客机,空重约占起飞重量的45%,机体寿命为4.5～5万小时,超音速飞行时机体表面温度大部不超过120℃,广泛应用机加整体结构,生产型机体整体结构占65%,1965年开始制造原型机,1979年停产,共生产16架,2003年11月停飞。 “Concord ” is a four-launched long-range jet supersonic passenger aircraft jointly developed by Britain and France. The airborne weight accounts for about 45% of the take-off weight and the life span of the aircraft is 4.5 to 50,000 hours. Most of the body surface temperatures during supersonic flight do not exceed 120 ℃. It is widely used to machine the overall structure. The overall structure of the production-type body accounts for 65%. The prototype machine was started in 1965 and was discontinued in 1979. The total production was 16, and the aircraft stopped production in November 2003.
