| Abstract: |
| The injector with a pin throttle in liquid bipropellant thrust-variable rocket engines has the superiority of fast response and the disadvantages of high mixture ratio deviation and unreliable shutdown. In this paper, a simple a-nd reliable design of the injector able to overcome the disadvantages mentioned above is presented based on the analysis of its flow characteristics, which is experimentally proved reasonable and reliable. |
