| Abstract: |
| Focused on the stability analysis for a turbo pump experiment system with a gas generator,a throttle and a technical nozzle.By calculating the main pole point orbit of the linear part of the state equations of the system,effect of the design parameters on stability of the system was analyzed,and the stability margin was obtained. |
| Key words: Liquid propellant rocket engine Turbine pump Dynamic characteristic Stability |
