摘要: 本文叙述气动调节喷管性能计算的分析程序。应用此方法对一种气动调节喷管模型进行了性能计算,并将得出的推力特性,抽吸特性,及面积比的变化跟喷管模型的实验数据,做了比较,结果表明:二者符合较好。

Abstract: An analytical procedure for computing the performance of aerodynamically variable geometry exhaust nozzle is presented in this paper.We calculate the performance of a scale nozzle model by using this method and compare in terms of thrust coefficient,pumping characteristics,area ratio variation with the data obtained from scale nozzle model test.The results of this comparison indicate good agreement between them.
