Abstract

The Crew Escape System (CES) is a dedicated system to ensure crew safety in Human Spaceflight Program (HSP) and will be called into action in case of exigencies at the launch pad or during the entire duration of the first stage operation of the launch vehicle. The CES primarily consists of a set of quick acting solid motors among them is a jettisoning motor.


A static test was successfully carried out in vertical mode to gather extensive data on the motor performance. Data recorded in static test was comparable to the pre-test prediction. The overall performance of motor with respect to thermal, structural integrity, interfaces was normal. The intricacies involved in the development of the CJM motor are presented in this paper.
