Advanced Rocket Motor System Design for Enhanced Flight Performance and Safety

This project presents the design and development of a rocket motor system incorporating a highly efficient fuel grain made of R-45M resin, cross-linked with diisocyanate. Key components include a lightweight 6061-T6 aluminum motor housing, a high-temperature ceramic composite nozzle, and an ignition system optimized for reliability. The motor is static-tested to 1200 psia and designed for a maximum altitude of 10,641 feet AGL with a burn time of 5.4 seconds. Safety protocols for fuel mixing, including dry and liquid chemicals, ensure optimal performance and minimize risks.
