摘　　要：简要介绍了凝胶推进剂的流变特性,将其流动过程分为三个阶段,列举出了适用于不同剪切速率下的本构方程。介绍了双股撞击式、三股撞击气动式、同轴离心式、脉动式喷注器凝胶推进剂雾化特性研究的现状,指出了影响雾化模式的多种因素及目前研究中存在的问题。The rheological characteristics of gelled propellants are introduced briefly. The flow behaviors are classified as three stages and the constitutive equations applied to different shear rates are described. The status of atomization research of gelled propellants with the doublet impinging jet injector, triplet air-blast atomizer, coaxial-swirl injector, pulsatile injector is summarized. Various factors which affect the atomization modes and some problems existing in present atomization research are pointed out.
