本发明介绍一种使用液体燃料和固体推进剂的冲压发动机。使用液体燃料的火箭发动机要由其本身供应氧化剂,以便液体燃料能够燃烧。这就使系统的重量大大增加,从而降低了有效载荷能力。当人们发现氧在空气中以自然态存在时,并没有在这些系统中得到应用,因为要使液体燃料燃烧,还没找到使空气充分压缩的方法。 The present invention describes a ramjet engine using liquid fuel and solid propellant. Rocket engines that use liquid fuels are supplied with oxidizer by themselves so that the liquid fuel can burn. This greatly increases the weight of the system, thereby reducing the payload capacity. When oxygen is found in the air in its natural state, it has not been applied in these systems because no method has been found to sufficiently compress the air in order to burn the liquid fuel.
