研究了含钾盐的硝化棉基钝感推进剂的燃烧性能。结果发现:钾冰晶石(K3AlF6)的加入严重地破坏了钝感推进剂的平台燃烧效应,而消焰剂KD对平台的破坏作用较小。含KD的推进剂燃速和平台范围可通过组合催化剂的变化来调节。BTTN取代TMETN后,燃速有所增加,平台效应得以保持。添加硝基胍(NGu)使得推进剂在8～9MPa燃速发生“突跃”,高压下有平台区出现。 The combustion performance of nitrocellulose-based detergency propellants containing potassium salt was studied. The results showed that the addition of potassium cryolite (K3AlF6) severely damaged the platform combustion effect of insensitive propellants, while KD flame retardant KD had little effect on the platform. KD-containing propellant burn rates and platform ranges can be adjusted by combining catalyst changes. BTTN replace TMETN, the burning rate has increased, the platform effect can be maintained. The addition of nitroguanidine (NGu) resulted in a “sudden jump” of the propellant at a burning rate of 8 ~ 9MPa and a plateau zone under high pressure.
