Ramjet engines have traditionally used liquid fuel which is mixed with atmospheric air and burned to provide thrust for high-speed flight.

传统的冲压喷气发动机使用液体燃料并与大气中的空气混合燃烧，以提供高速飞行的推力。

This design created a gap between the air intake and the forward fuselage, and requires six small beams to enhance the structure for high-speed flight.

这样的设计导致了机身与进气口之间有一个间隔，为了高速飞行而在之间使用了6条小加强筋以加固结构。
