Analysis of Abnormal Ignition Current of Ground Firing Control System and Improvement of Ignition Circuit
Aiming at the problem of abnormal ignition current of a certain type of rocket launcher ground firing control system,the mathematical method is used to study the change law of ignition current and component parameters and the fundamental cause of instability of ground firing control current under some environments is found.Finally,a closed-loop control scheme is proposed to solve the problem of abnormal ignition current by adding current feedback link.The practical application shows that the improved ignition circuit can adapt to larger ignition load and can effectively improve the reliability of the ignition.
