thrust index
解釋
推力指數-
Calculating result showed : the thrust changing caused by the magnitude of at / ac was more larger than that both of the pressure index : " n " and of the chamber diameter, and the best thrust could be get when at / ac < 0. 3
由數值計算可知, at ac的大小變化所引起的推力變化比壓力指數n和藥室直徑的變化引起的變化大得多,而且當at ac 0 . 3時,可以得到最佳的推力效果。
