Design of electronic delay ignition device for a certain type of HESH

Aiming at the low precision of the gunpowder delay body of a certain type of HESH (High-explosive squash-head), an electronic delay ignition device was used to replace the traditional delay body. The design uses an independent setter to charge the electronic delay ignition device, set the delay time and detect the online status,etc. The delay time of HESH can be adjusted within the predetermined range, and the precision of the delay ignition time can be improved from 0.6s to 0.03s,which can obviously improve the performance of HESH.
