高能高密度材料组成的低信号特征固体推进剂

采用含能粘合剂ＴＧＡＰ，ＴＢＡＭＯ，增塑剂ＢＴＴＮ和ＡＺＰＬ－４以及氧化剂ＨＮＩＷ组成一种新型的无铝无氯推进剂，从理论上对这种高能高密度材料的组成的推进剂的能量特性、工艺性能、燃烧性能及安全性能作了分析和评估。结果表明，对于ＨＮＩＷ含量为８４％的配方，ＡＺＰＬ－４或ＢＴＴＮ为７％时，其理论比冲分别为２５５ｓ和２５８ｓ，密度分别为１．８８７ｇ／ｃｍ３和１．９１２ｇ／ｃｍ３，氧系数大于１．１；用少量的铝粉代替ＨＮＩＷ，其理论比冲、密度明显上升；８４％固体含量的推进剂仍可采用现有浇注装药工艺。由此可见，这类仅由Ｃ，Ｈ，Ｏ，Ｎ四种元素组成的推进剂的氧系数较高，可制成有较好综合性能的低信号特征复合团体推进剂。

MINIMUM SIGNATURE COMPOSITE SOLID PROPELLANTS CONTAINING HEGH ENERGY-DENSITY MATERIALS

The minimum signature solid propellants containing energetic binder TGAP orTBAMO,plasticizers AZPL-4 or BTTN and oxider HNIW are discussed in this paper .Theenergetic performance ,processing technology , burning behaviour ,mechanical property are paper .Thetheoretically ,The results shows that the specific impulse fo this propellants is 255 s or 258 s,thedensity is 1. 887 g/cm3 or 1. 912g/cm3,when the solid content of HNIW is 84%,the plastcizer PAZPL-4 or BTTN is 7% and the oxygen coefficient is more than 1.1, The theoretical specific impulse increases significatly when low aluminium content used to replace HNIW .So thepropellants containing high energy -density materials (HEDM) in the paper are the most promisingminimum signature composite solid propellants .
