战术攻击导弹发动机用丁羟推进剂配方研究

RESEARCH OF HTPB PROPELLANT FORMULATION USED FOR TACTICAL ATTACK MISSILE MOTOR

本文介绍了一种燃速在２５～３０ｍｍ／ｓ之间可调，最低比冲２３５４Ｎ·ｓ／ｋｇ的丁羟高燃速推进剂配方。该配方具有较低的压强指数（ｎ＜０．４），良好的工艺性能（药浆放置５ｈ后，其５０＜７００Ｐａ·ｓ）和力学性能（常温σ＿ｍ＝１．０ＭＰａ，－４０℃ε＿ｍ＞３０％），故具有实用价值。

A promising HTPB propellant formulation is presented in this paper Itsburning rate can be regulated from 25 to 30mm/s and the specific impulse is greater than2354N· s/kg,pressure exponent n<0.4.Furthermore,the processability(slurry 5h 50<700Pa· s)and mechanical strength(25℃, σ_m=1.0MPa,-40℃,ε_m>30%)are satis-factory to practical requirements.
