In solid rocket motors which rotate during operation, the combustion behavior is significantly different from ordinary motors because of centripetal acceleration. Most of the existing combustion rate prediction models are complex and require the support of material parameters and empirical parameters. To simplify the calculation while maintaining simulation accuracy, a novel burn rate prediction model, which tries to minimizes the physical simulation requirements and mainly relies on free parameters to fit actual burn rate distribution, is proposed in this article. The proposed model is proven to fit with the experiment data accurately, and doesn’t require fluid or thermo-chemical simulations.
