Prediction of solid rocket motor performance characteristics using computational fluid dynamics and validation with experimental data

Abstract

Solid Propulsion is widely used in Missile and Space applications. Accurate prediction of Specific impulse (Isp) is important for design of Solid rocket motor. These predictions can be done using empirical relations. Obtaining these empirical relations require large amount of data. The renowned aerospace organizations use their own code for prediction. These codes are not open source and also developing a code requires big team effort with challenges of verification and validations. The present work is aimed at developing numerical model for prediction of Specific Impulse. The model is validated against the experimental data of static test of solid rocket motor taken from literature.
