abstract = "In order to study the influence of low-pressure conditions on the ignition performance of AP/HTPB/Al composite propellant，the ignition delay time and ignition critical pressure of AP/HTPB/Al mixture were tested and analyzed by laser ignition and high-speed photography visualization technology. The results show that the ignition delay time of AP/HTPB increases with the decrease of pressure at low pressure，and the ignition delay time of AP/HTPB at 0.02 MPa is 31\% longer than that at normal pressure. The smaller the AP particle size is，the shorter the ignition delay time of AP/HTPB and the lower the ignition critical pressure is. When the AP particle size increases to more than 109 μm，the ignition critical pressure of AP/HTPB is stabilized at 0.06 MPa. With the increase of AP content，the ignition delay time of AP/HTPB decreases first and then increases. When the AP content is 80\%，the ignition delay time of AP/HTPB is relatively short. With the increase of nano-Al content（5\%\textasciitilde{} 15\%），the ignition delay time and ignition critical pressure of AP/HTPB/Al decrease obviously. The increase of micron Al content makes the ignition delay time and ignition critical pressure of AP/HTPB/Al show the opposite variation.",
