Computation shows that the spinning of SRM makes the pressure in combustion chamber high, action time short and the pressure descending stage long.
旋转和不旋转情况下的计算结果对比表明，旋转使发动机内压强增高，工作时间缩短，拖尾段加长。

The aircraft engines are the primary source of compressed air in flight. The air is bled from the 7th or 10th stage of the engine HighPressure (HP) compressor.
飞行中，发动机是主要的气源。空气由发动机高压压气机第7级或第10级引出。
