摘要
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 properties of insensitive nitrocellulose based propellant containing potassium compounds as flash suppressors investigated in this paper. The results indicate that the addition of K 3AlF 6 badly destroys the plateau burning effect of insensitive propellant, while flash suppressor KD almost do not destroys the platonisation.The burning rates and the plateau range of the propellant containing KD can be adjusted by means of the change of composite catalysts. After 1,2,4 butanetriol trinitrate (BTTN) is substituted for trimethylolethane trinitrate (TMETN),the burning rates of the propellant increases apparently and the plateau effect is maintained. Nitroguanidine (NGu) enables the propellant to appear burning rate jump between 8 and 9 MPa and to produce plateau burning effect under higher pressure.
