摘　　要：为强化燃烧，让复合推进剂中的铝粉表面包覆一种高分子表面活性剂。燃烧过程中这种活性剂形成不可渗透的壳层，可通过破裂燃烧的方式使铝粉快速完全的燃烧。激光点火实验初步验证了这种设想的可行性。Ｔ形燃烧器的实验结果表明，使用包覆铝粉的推进剂，燃烧室管壁残存的残渣量和残渣中大粒子所占的百分数显著减少。In order to accelerate burning,aluminum particles surface of composite propellant is coated with a type of macromolecular surface active agent, which forms an impermeable shell in the combustion process.So that aluminum particles are rapidly and completely burnt out by means of disruptive burning.Laser ignition experiments demonstrate tentatively the feasibilty of the idea.And the results of T burner experiment show the residues on the tube wall of combustion chamber and percentage of large particles decrease significantly because of using the coated aluminum particles in the solid propellant.
