本文叙述了实验研究硝胺对平台双基推进剂燃速的影响。平台推进剂中加入奥克托今消除麦撒和平台燃烧区域並大大降低燃速。压力指数随着奥克托今含量增加而增加;当加入6.5％奥克托今时会使麦撒燃烧效应減少。然而,加入26.8％奥克托今时,可保持平台燃烧效应(压力指数约为0.2),並可扩大平台压力范围。这些燃速特性使火箭发动机中于宽广的压力范围内有可能稳定燃烧。这些对于发展实
This article describes the experimental study of nitramine on the platform of double base propellant burning rate. Adding Octoctant to the platform propellant now eliminates the burning area of the MSAR and platform and greatly reduces the burning rate. The stress index increased with the Occurrence present; the addition of 6.5% Ocotillo now reduced the burning effect of the Macha. However, with 26.8% Octoctor, the platform combustion effect is maintained (pressure index is about 0.2) and the platform pressure range can be expanded. These burnout characteristics make it possible for the rocket engine to burn stably over a wide range of pressures. These are real developments
