Abstract

A portable rocket motor test stand is essential for evaluating rocket motor performance and components such as the tube, propellant, igniter, and nozzle. Preliminary assessment with this equipment before the RX 200 rocket flight test is crucial, requiring meticulous design calculation for functionality. This study aims to investigate thrust force variations of 10,000, 12,000, 14,000, and 16,000 N. The portable rocket motor test stand employs Aluminium 6061-T6, chosen for its low density, corrosion resistance, and moderate strength. Finite element analysis conducted using Ansys Workbench software evaluates structural integrity. Results from fatigue simulation indicate that the portable rocket motor test stand fails to achieve a service life of 1 million cycles at a thrust of 16,000 N.
