本文研究了AP/HTPB固体叠层推进剂对压力扰动的火焰响应。实验在1 MPa压力下进行。压力扰动由连接到燃烧室端部的脉冲发生器系统产生。用显微镜和高速摄影机记录了AP/HTPB三层结构的燃烧过程。定性分析的火焰图像的两种情况下，有和没有压力波动，发现在管中建立的驻声波强烈影响了火焰和燃烧产物的流动。火焰响应由燃烧表面上方的振荡运动转化。因此，燃烧表面轮廓发生了变化，这意味着回归率值可能会波动。
The experimental work presented in this paper deals with the flame response of a solid laminate propellant AP/HTPB to pressure perturbations. Experiments were performed in closed tube pressurized under 1MPa. The pressure perturbations are created by a pulser system connected to the end of the combustion chamber. The combustion process of a three layers of AP/HTPB was recorded by using a microscope and a high speed camera. The qualitative analysis of the flame images of the two cases, with and without pressure fluctuations, revealed that the standing acoustic waves established in the tube has strongly affected the flame and the combustion products flow. The flame response was translated by an oscillation motion above the burning surface. Thus, the burning surface profile was changed which means that the regression rate value may fluctuate.
