| Abstract: | The principle of low frequency unstable burning of the 85% H_2O_2-PE hybrid rocket motor is analyzed. A one-dimensional simulation of low frequency coupled oscillation combustion of the hybrid rocket motor is performed by using mass conservation equations. The effect of reduction of oxidizer injection pressure on low frequency unstable burning is discussed. On the basis of a perturbation analysis, the stability limits of the hybrid rocket motor is derived and the methods of suppressing low frequency coupling oscillation combustion of the hybrid rocket motor are suggested. |
