引言本文发表了航天飞机主发动机在地面点火期间瞬间产生的侧向载荷分析结果,这个侧向载荷主要是由于发动机喷管中气流流动分离造成的,上述分析结果是采用蒙特卡洛(Monte Carlo)动载荷分析方法得到的。象航天飞机主发动机那样具有高面积比喷管的发动机,在点火期间产生的这种侧向载荷干扰,是一种瞬态现象。本文还修正了过去发表的文献,其中包 INTRODUCTION This paper presents the results of a lateral load analysis of the shuttle main engines instantaneously during the ignition on the ground. This lateral load is mainly due to the separation of the airflow in the engine nozzle. The above analysis is based on Monte Carlo Dynamic load analysis method. This type of lateral load disturbance, which occurs during ignition, is a transient phenomenon, as is the main engine of a space shuttle with a high area ratio nozzle. This article also fixes the previously published literature, which package
