这是改进导弹,尤其是整体式火箭冲压发动机推进导弹的发明专利。导弹结构大致可分为前、后两大段,前段内装有战斗部和制导系统,后段由推进系统构成。典型的火箭冲压推进系统包括一个装有火箭推进剂的燃烧室和在这个室前面的冲压发动机燃烧系统,以及火箭推进剂燃完后,冲压发动机工作时用于吸入空气的进气道。为了发射方便和在导弹加速期间避免阻力过大,进气道通常可装在圆柱形弹体内。有些导弹采用4个进气道,当导弹加速到足够的速度时,通过小的爆炸装药将进气道的堵盖去 This is an invention patent for improving missiles, especially integrated rocket ramjet propulsion missiles. The missile structure can be broadly divided into two parts, front and back. The front part is equipped with a warhead and guidance system, and the rear part is made up of a propulsion system. A typical rocket-propelled propulsion system includes a rocket-propellant-equipped combustion chamber and a ramjet combustion system in front of the chamber, as well as an intake for drawing in air when the ramjet works after the rocket propellant is fired. In order to facilitate launching and to avoid excessive drag during missile acceleration, the intake duct can usually be mounted within a cylindrical body. Some missiles use four inlets, and when the missile accelerates to a sufficient velocity, it blocks the intake by a small explosive charge
