Abstract
In this paper, specific grains burn back is presented by new geometrical method. The software is developed for Wagon wheel grains and 3D grains. Rapid solid motor ballistic simulation code produces required charts with considered nozzle geometry. Presented method used geometrical introducer point (GIP) to produce the various grains. Limitations and configurations are simply modeled. Thrust, total pressure and temperature are illustrated as web burned changing. The results confirm the performance of the developed algorithm for mentioned grain analysis. Lower time processing and rapid ballistic analysis are the benefits of the presented algorithm. Finally results of the burn back analysis code and the internal ballistic simulation code are evaluated by some other existent codes and real cylindrical grain test.
