综述了CTPB(端羧基聚丁二烯)型、HTPB(端羟基聚丁二烯)型、PET(环氧乙烷–四氢呋喃共聚醚)型、GAP(聚叠氮缩水甘油醚)型等4种复合型燃气发生剂近年来的研究进展,并总结了其应用特点。在均采用AP(高氯酸铵)为氧化剂的条件下,GAP型燃气发生剂的燃温最高,而CTPB型燃气发生剂的燃温最低,HTPB型燃气发生剂的产气量最大。
Four kinds of CTPB (carboxyl terminated polybutadiene), HTPB (hydroxyl terminated polybutadiene), PET (ethylene oxide - tetrahydrofuran copolyether) and GAP (poly azide) The research progress of compound gas generants in recent years and its application characteristics are summarized. In the case of using AP (ammonium perchlorate) as oxidant, the gas temperature of GAP gas generator is the highest, while that of CTPB gas generator is the lowest, and that of HTPB gas generator is the largest.
