丁羟推进剂吸湿分级
Degree of moisture absorption HTPB propellant
摘要
Abstract
With HTPB propellant as research object,some moisture absorption tests were performed under various conditions. The tests of the propellant carton dipping into the water and the drying recovery of the propellant were performed, and the effect of drying recovery on the heat value of the propellant with different moisture absorption percentage was investigated. Three dividing lines of moisture absorption based on agglomerate water existing in the surface of moist propellant or not, the adhering interface of filling,the recovery degree of hardness and heat value were determined,I. E. Moisture absorption percentage equals 0.04% ,0. 15% and 5 % . The characteristics of propellant with different degree of moisture absorption were analyzed, and the corresponding measures which should be taken in disposal were proposed.关键词
