| Abstract: |
| The ignition process is important in the detonation wave engine.The process of ignition is relevant to the filling and the detonation formation processes.The control factor of the ignition is defined and the method to calculate the ignition delay is given and the law of the ignition delay changing is analyzed.The effect factors of the ignition frequency is analyzed.On the basis of above analysis,the control law of ignition is acquired,which is the base of ignition control system design. |
