摘　　要：环境压力是影响底排性能的重要参数之一 .由风洞实验获得来流压力、M数及排气参数等对复合底排药减阻性能的影响 ,以及药剂燃速和排气温度随静压的变化 。Ambient pressure is an important parameter for base bleed performance. The influences of pressure and mach number of freestream and ejection parameter on drag reduction of base bleed are obtained by wind tunnel experiments. The variations of temperature of base burning and burning rate of propellent with ambient pressure are also received. The effect mechanism analysis is explained in theis paper.
