肼-70胶体推进剂的特性及制备方法

胶体推进剂是火箭推进和其它燃气发生器的新型待选推进剂。常规液体推进剂在储存过程中泄漏危险性较高，将液体推进剂制成介于固体与液体之间的胶体，可大大增加其粘度与表面张力，降低泄漏危险性。文中对肼-70胶体推进剂的国内外研究现状作了概述，着重对其制备工艺进行了具体介绍，包括胶凝剂的选择、分散工艺等方面，并通过实验对比发现对于肼-70体系而言，添加相同含量的B类胶凝剂成胶效果优于A类胶凝剂。

Properties and preparation of gel propellant H-70

Gel propellant is a new kind of propellant for rocket propulsion and other gas generator. Conventional liquid propellant may leak out during conserving. Make the liquid propellant gelled can increase the viscosity and the surface tension of the propellant, and reduce the probability of leaking. This paper presented a survey on the research of the gel propellant H-70, especially the preparation technics, including selection of the gellant and the disperse etc. The test results comparison of different gellants indicated that gellant B is better than gellant A for H-70.
