The coupled influence between structure and internal flow field will make the pressure oscillation during working process of the solid rocket motor. This coupled effect will bring the dynamic press on the payload and extremely destroyed the payload. For researching the influence of internal flow field by the deformation of inhibitor, the parallel fluid structure interaction method with the large eddy simulation model was used to analyze the solid rocket motor with segments. The results show that the deformation of inhibitor will influence the internal flow field parameter’s distribution and enhance the pressure frequency and amplitude remarkably. The partitioned method could solution the fluid structure interaction problems in the segmented solid rocket motor properly.

The Impact

An advanced and intensive computational solution development is integrated with an asymptotic technique, to examine the impact of the combustion surface morphology on the generated rotational flow field in a solid rocket chamber with wide ranges of forcing frequencies. The simulated rectangular chamber is closed at one end and is open at the aft end. The upper and lower walls are permeable to allow steady and unsteady injected air to generate internal flow mimicking the flow field of the combustion gases in real rocket chamber. The frequencies of the unsteady injected flow are chosen to be very close or away from the resonance frequencies of the adapted chamber. The current study accounts for a wide range of wave numbers that reflect the complexity of real burning processes. Detailed derivation for Navier-Stokes equations at the four boundaries of the chamber is introduced in the current study. Qualitative comparison is performed with recent experimental work carried out on a two-inch hybrid rocket motor using a mixture of polyethylene and aluminum powder. The higher the percentage of aluminum powder in the mixture, the more the corrugations of the combustion surface. This trend is almost similar to the computational and analytical results of a simulated solid rocket chamber.
