膏状推进剂是把燃料和氧化剂融于一体的固液悬浮体系，燃烧方式主要采用从贮箱挤入燃烧室或直接浇入发动机进行端面燃烧。美国近年的高能量密度材料计划中，正在研制“可变粘度”的膏状推进剂。　　近年来，俄罗斯、乌克兰的膏状推进剂的研制水平领先于美国，包括快燃膏状推进 Pasty propellant is a solid-liquid suspension system that integrates fuel and oxidizer. The combustion mode mainly uses squeezing into the combustion chamber from the tank or directly into the engine for end-face combustion. In the United States in recent years, high energy density material program, is developing a “variable viscosity” paste propellant. In recent years, Russian and Ukrainian cream propellants have developed ahead of the United States, including fast fuel paste
