In this paper, we developed a HTPB propellant containing energetic compound hydrated‐tetra‐(‐amino‐1,2,4‐triazole) copper perchlorate (ACP) as the fuel for variable thrust motor with the purpose of controlling gas flow. Formulation of the propellant was designed and then various performances of this propellant were investigated. Results show that HTPB propellant containing 2 % ACP has a pressure exponent of 0.57 (static) or 0.56 (dynamic), suggesting an excellent capacity to control the burning rate. Thermal decomposition of ACP and the decomposition of ammonium perchlorate (AP) in high temperature are demonstrated to be sensitive to pressure by PDSC analysis, moreover, decomposition of AP in high temperature (around 400 °C) could be accelerated by ACP, φ 50 mm motors charged with this propellant work stably in the pressure range from 1.18 MPa to 21.72 MPa and less aluminum (Al) deposits in chambers and nozzles. Mechanical performance of the propellant in −40 °C and 20 °C turns out to be excellent with σm≥0.96 MPa and ϵb≥20.92 %, and is better than that in 50 °C. Low impact sensitivity (H50, 72 cm) and friction sensitivity (P, 31 %) of HTPB propellant containing 2 % ACP are found in the security tests, the propellant is also insensitive to shock wave (G50, 23.8 mm).

可变推力电动机的有希望的燃料：具有高压指数的HTPB推进剂
在本文中，我们开发了一种HTPB推进剂，其中含有高能化合物水合四（（氨基）1,2,4-三唑）高氯酸铜（ACP）作为可变推力电动机的燃料，目的是控制气流。设计了推进剂的配方，然后研究了该推进剂的各种性能。结果表明，含2％ACP的HTPB推进剂的压力指数为0.57（静态）或0.56（动态），表明具有极好的控制燃烧速率的能力。PDSC分析表明，ACP的热分解和高温下的高氯酸铵（AP）分解对压力敏感，此外，ACP可以促进AP在高温（约400°C）下的分解，φ装有这种推进剂的50毫米电动机在1.18 MPa至21.72 MPa的压力范围内稳定工作，并且在腔室和喷嘴中沉积的铝（Al）更少。在-40°C和20°推进剂的机械性能Ç原来是优异的与σ米≥0.96兆帕和ε b ≥20.92％，并且比在50℃更好。低的冲击灵敏度（ħ 50 72厘米）和摩擦感（P含有2％ACP HTPB推进剂，31％）在安全测试中发现，推进剂也不受冲击波（ģ 50 23.8毫米）。
