| Abstract: |
A new, improved fidelity solid rocket ballistics model will be built on a commercial CFD platform. The CFD platform includes a coupled solid mechanics solver, allowing for tight coupling between the grain burnback and the motor gas dynamics. An aero-acoustic component of the platform will be used to determine mode shapes and acoustic decay characteristics from the ballistics results. |
| Benefits: |
The planned model developments will provide improvements in predictive capabilities as new solid rocket motors are designed. The result should be fewer and less severe instabilities experienced during the development process, accompanied by lower development costs and less schedule risk. This product will benefit both government and commercial sector motor developers. |
