摘要
研究揭示环境压力是复合推进剂底排性能的重要影响参数。底排减阻率、排气温度及药剂燃速随环境压力发生明显变化。利用研究结果修正底排底阻计算方法，显著提高了计算精度，计算结果与靶场实验数据符合良好。
This investigation shows that ambient pressure is an important performance parameter for base bleed of propellent.The drag reduction rate,temperature of base bleed and burning rate of propellent variate obviously with ambient pressure.The calculating precision of base drag of base bleed is increased greatly,when the method corrected by using this investigation results,and the values are correspondent with flying tests.
