四个向外倾斜的喷管把固体火箭发动机的排气流分成四个相等的尾巴。
Four nozzles, canted outboard, split the exhaust of the solid rocket motor into four equal tails.
声压级在相交激波点附近出现剧烈变化，喷管出口处的激波和排气羽流造成强噪声。
The sound pressure level changes acutely in shock intersection, and shocks outside nozzle and exhaust plume cause strong noise.
从理论上证明：对这两类发动机的两相喷管流动特性可以通过一个共同的组合参数——当量排气速度来进行分析；
Theoretically, it is proved that for both these engines, the properties of two-phase flow in nozzle can be analysed with a common combined parameter which is equivalent to exhaust velocity.
