igniter

Taking aft-end igniter design for a rocket motor for example,design methods for ignition sequence,amorce quantity estimation and nozzle closure were described respectively.

以发动机尾点火设计对象,对点火序列设计、点火药量的估算、喷管堵片的设计方法进行了阐述。

The purpose of the bulkhead is threefold: to seal the forward end of the motor, to retain the pyrogen igniter, and to act as a blowout plug in case of motor overpressurization (discussed earlier).

的目的，该舱壁是三个方面：密封着年底汽车，保留热原点火器，并充当井喷堵塞在案件电机overpressurization （讨论以较早者准） 。
