Testing of ignition delay of second pulse of soft-clapboard dual-pulse motor

When doing the experiment of soft-clapboard dual-pulse motor, the delay time of the second pulse ignition was found exceeding the requirement. In order to improve the status, the experiments in terms of the quantity of ignition powder and the thickness of the soft-clapboard were carried out. The results show that increasing the ignition powder will promote the rupture of the clapboard and the release of the energy, and increasing clapboard thickness will not rupture the clapboard hopefully, and decrease the performance of motor. At last, according to the characteristic of the soft-clapboard dual-pulse motor, improving from the above two terms, the motor ignition can attain a good condition.
