不同粘合剂RDX/AP推进剂燃烧产物的分析研究

COMBUSTION PRODUCTS ANALYSIS OF RDX/AP PROPELLANT WITH DIFFERENT BINDERS

以聚醚、HTPB、NEPE三种不同粘合剂体系的RDX／AP少烟推进剂为研究对象，用裂解色谱-质谱联用技术分析了它们的裂解产物的组成。发现推进剂中所采用的粘合剂类型不同时，其裂解产物的组成和含量不同，NEPE少烟推进剂基峰44占70％，聚醚少烟推进剂基峰44只占10％，这是造成两类推进剂压强指数不同的原因。

Smoke reduced propellants with different binders such as HTPB, Polyether, NEPEare studied. The composition of the pyrolytic products are measured by PYGC-MS The result showsthat the products and their contents in pyrolytic processes are different. The measured valuerepresenting the 44 peak in the NEPE smoke-reduced propellant is 70% of the total value. while theone in the polyether smoke-reduced propellant is only 10%, which results in the difference in pressureexponent between these two propellants.
