推进剂药柱 meaning in Chinese
charge; propellant
propellant grain
propellant stick
Examples
- Interface debond between propellant and liner is a key form of failure of the structure integrity in the analysis of solid rocket motor
在固体火箭发动机结构完整性分析中,衬层/推进剂药柱粘接界面的脱粘是完整性被破坏的关键形式之一。 - Last , the result is compared with the result of analytic method . this paper provides a new method to analyze the grain structural integrality . the result provides the gist of grain figure in optimize design
通过这些计算和分析，为底排?火箭弹助推火箭推进剂药柱结构完整性分析的有限元法提供参考，为药柱药形的优化设计提供依据。 - The antiablation of silicone rubber liner can be improved both by changing the structure of unvulcanized rubber and adding antiablative fillers , and the bond strength between propellant charge and the liner would be increased largely by coating the primer liquid on the charge surface
硅橡胶包覆层中填料的粒径对硅橡胶的补强效果十分重要；可从改变生胶结构、添加耐烧蚀填料两方面来改善硅橡胶包覆层的耐烧蚀性；在推进剂药柱表面上涂覆底涂液可以大幅提高硅橡胶包覆层与推进剂的粘接强度。 - Because the propellant grain is viscoelastic material , the liner and adiabatic layer are also viscoelastic one , the interface debond problem is actually interface crack about elastic - viscoelastic or bi - viscoelastic materials . research about this problem relates to the knowledge of viscoelastic mechanics and interface fracture and combustion . numerical analysis method about interface debond on solid rocket motor is researched in this paper
由于固体火箭发动机的推进剂药柱是一种粘弹性材料,衬层和绝热层也具有粘弹性性质,因此其界面脱粘问题实际上是弹性-粘弹性或双粘弹性各向同性材料界面裂纹问题,对该问题的研究涉及到粘弹性力学、界面断裂力学和燃烧学等相关学科。
