[0039] The present invention can be used for auxiliary starting when the contact point air inlet is just opened and restarting control after no starting. The specific implementation is as follows:
[0040] 1. For the auxiliary starting when the relay point inlet is just opened, the following steps are included:
[0041] 1.1) Before the ramjet works, the main revolving valve rotates to the maximum position θ max At this time, the inlet of the intake port is sealed. At this time, the angle between the main rotating valve and the bottom wall of the intake port is the largest, and a shock wave is formed on the surface, the secondary rotating valve is closed, and the airflow does not enter the intake port;
[0042] 1.2) When the relay point is reached, the secondary valve opens to a certain degree, and then starts to rotate the main valve gradually (the angle between the main rotating valve and the bottom wall of the intake port decreases), the intake port gradually opens, and at the same ...
