测试了高氯酸铵/硝胺丁羟复合推进剂的热感度、摩擦感度和冲击感度。感度的测试结果表明,用硝胺RDX或HMX部分取代AP制成硝胺丁羟复合推进剂后,这种复合推进剂的感度要高于仅含高氯酸铵的推进剂的感度;随着RDX或HMX含量的增加,其感度值随之增大,但增幅逐渐下降。但在高氯酸铵推进剂中加入卡托辛燃速催化剂以后,制成的高燃速推进剂,其摩擦感度明显增大。 The thermal sensitivity, friction sensitivity and impact sensitivity of ammonium perchlorate / nitramine-hydroxy composite propellants were tested. Sensitivity test results show that the nitroamines RDX or HMX partial replacement AP made nitramine hydroxy composite propellant, the composite propellant sensitivity is higher than the ammonium perchlorate propellant sensitivity; with the RDX or HMX content increases, the sensitivity value increases, but the increase gradually decreased. However, adding ammonium catalyst in the ammonium perchlorate catatoxin burning rate catalyst made of high burning rate propellant, its friction sensitivity increased significantly.
