1.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.
以某型号发动机尾设计为研究对象,对序列设计、药量的估算、喷管堵片的设计法进行了阐述。
2.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).
