Abstract

Glycidyl azide polymer-energetic thermoplastic elastomer propellant (GAP-ETPE) has high development prospects as a green solid propellant, although the preparation of GAP-ETPE with excellent performance is still a challenge. Focusing on the demand of high-strength solid propellants for free-loading rocket motors, a GAP-ETPE model propellant with excellent overall performance was prepared in this work, and the influence of adhesive structure characteristics on its fluidity was studied. Furthermore, the influence of filler on the rheological properties of the model propellant was investigated by introducing hexogen (RDX) and Al, and a corresponding two-phase model was established. The results may provide a reference for the structural design, molding process, and parameter selection of high-performance GAP-based green solid propellants.

摘要

缩水甘油叠氮聚合物-含能热塑性弹性体推进剂（GAP-ETPE）作为一种绿色固体推进剂具有很高的发展前景，尽管制备具有优异性能的GAP-ETPE仍然是一项挑战。针对自由装填火箭发动机对高强度固体推进剂的需求，本文制备了一种综合性能优异的GAP-ETPE模型推进剂，并研究了粘合剂结构特性对其流动性的影响。此外，通过引入黑索今（RDX）和铝粉，研究了填料对模型推进剂流变性能的影响，并建立了相应的两相模型。研究结果可为高性能GAP基绿色固体推进剂的结构设计、成型工艺及参数选择提供参考。
