Title: Improved Thrust Termination Modeling for Solid Rocket Motors
Agency: DOD
Contract: HQ0147-11-C-7602
Award Amount: $99,917.00
 

Abstract:

To improve the predictive capabilities of solid rocket motor end-of-burn phenomena, two analysis tools will be further developed. An existing engineering tool will go through continued development and validation, while an existing solid rocket ballistics model, built and demonstrated within a commercial CFD platform, will be expanded to allow for conjugate heat transfer between the burning grain and the motor internal insulation and casing. The CFD platform includes a coupled solid mechanics solver, allowing for tight coupling between the grain burnback and the motor gas dynamics. Addition of the internal insulation and motor casing should be direct application of existing modules. Development of a slag generation and subsequent particle tracking capability will enhance the existing tool.
