In this situation (called'underexpanded') what we call expansion waves (that produce gradual turning and acceleration in the jet) form at the nozzle exit, initially turning the flow at the jet edges outward in a plume and setting up a different type of complex wave pattern.
在这种情况下我们所谓的膨胀波（即生产逐步转向和加速度，在射流）形式在喷嘴出口，最初把流在射流边缘向外，在羽流，并设立不同类型的复杂的波形。
That conversion is accomplished by the combustion of the propellants in the combustion chamber, followed by acceleration of the hot gas through a convergent/divergent nozzle to achieve high gas velocities and thrust.
转换是通过燃烧的推进剂在燃烧室，其次是加快了热气体通过一个收敛/发散喷嘴，以实现高瓦斯速度和推力。
