向冲压发动机供应环境空气用的空气捕获和输送机构早就在采用了。通常,冲压发动机推进飞行器时,从环境获得的空气同燃料要在一个曾用作助推器的燃烧室中燃烧。进气斗必需很大,以便能够容纳所需的空气量,但又得有足够的结构完整性,以便飞行器表面相对突 Air capture and delivery mechanisms for supplying ambient air to ramjet engines have long been in use. Typically, when ramjet propel aircraft, ambient air is combusted with fuel in a combustion chamber that was used as a booster. The intake hopper must be large enough to accommodate the amount of air required but yet have sufficient structural integrity for the aircraft surface to project relatively
