球形铝粉在丁羟固体推进剂中的应用

Uss of Spherical Aluminium Powdor in Hydroxy-terminated Polybutadiene Propellants

在固体火箭推进剂中,用球形铝粉代替非球形铝粉的实验结果表明,含球形铝粉推进剂的单向拉伸性能、工艺性能比含非球形铝粉的推进剂有明显改善,只是燃速略有下降,其他性能相当。

It is demonstrated by experiments that, compared with propellants containing non-spherical aluminium powder for both strategic and tactic rocket motors, propellants containing spherical aluminium powder can improve unilateral tension property and processing performance evidently with other similiar properties, except for lower burning rate.
