Quality Assurance Challenges for Development of Crew Escape System Motors

Crew Escape System (CES) motors for Human Rated Launch Vehicle (HRLV) have been newly designed. These solid motors have special nozzle configuration. The development of these motors was a challenging task due to stringent design specification and intricate nozzle configuration. This paper emphasizes the fabrication challenges encountered during realization of CES hardware, details of process and quality improvement done, to overcome the challenges faced during fabrication and to achieve the stringent geometrical requirements and dimensional accuracies as specified by designer.
