Paramiter Analysis of the Working Process of Solid Impulsive Microthruster
摘要
Abstract
Solid impulsive microthruster bears transient property on the working process, and has coupled character on heat transfer.In the paper, 2-D transient simulation is carried on the working process of microthruster by dynamic mesh model.Interior ballistics process is calculated with different a-morce quantity and different unbolted pressure of nozzle, and the influence of amorce quantity on interior ballistics is analysed.Through calculating the flow in the conditions of shell heat insulation and coupled heat transfer, the influences of different heat transfer conditions on microthruster performance are ana-lyzed.At last, the result of simulation is contrasted with experimental data, and the matter of accuracy to forecast interior ballistics is pointed out.关键词
