查询词典 liquid propellant

The operating process of liquid apogee engine (N2O4/MMH) thrust chamber is studied. By applying the SIMPLE algorithm with staggered grid, the numerical model is established. The atomization mechanism and decomposition combustion of hypergolic rocket propellant are considered in the model.

研究了远地点发动机(N2O4/MMH)的推力室工作过程，考虑了自燃推进剂的雾化、蒸发以及化学反应流动过程，采用交错网格系统的SIMPLE算法，得到了不同边区冷却流量对推力室的内流场和燃烧效率的影响结果，数值计算的结果与理论分析相符合，为推力室工作过程的稳定性分析提供了重要参考。

The liquid chromatographic behavior of centrale under different conditions were investigated, and a method for the determination of the content of centralite in propellant by HPLC was established.

考察了在不同试验条件下发射药中二号中定剂的液相色谱行为，从而建立了二号中定剂的高效液相色谱测定方法。

With the development of combustion research and the temperature measurement as well as relevant techniques, the flame temperature measuring techniques begin to enter the common industry fields from labs, and extend to the aviation and aerospace industry. At the beginning of the 1980s, the Ijumdien Institute in Holland began to develop many industry flame temperature measurement installations based on thermal couples. And later, the National Aerospace Administration also successfully employed the Coherence Anti-stokes Raman Stokes in the flame temperature diagnostic of the precombustion chamber of space shuttle main engine (SSME, liquid H〓/O〓 propellant).

随着燃烧研究的深入和温度测量及其相关技术的不断发展，从1980年，火焰温度测量技术开始由实验室走向工业现场、从一般工业现场走向航空航天领域：欧洲以荷兰的Ijmuiden研究所为代表，研究开发了很多基于热电偶的工业燃烧火焰温度测量装置；美国国家航天局则成功地将相干拉曼斯托克斯方法用于航天飞机的主发动机（SSME，液氢液氧发动机）预燃室燃烧火焰温度诊断上。

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 charg...

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。
