Title: Securing and arming of multistage accelerated missile - causes misfire with available electrical energy dissipated in shorter time unless arming acceleration duration is sufficient
Inventor: REHMANN ROBERT
IPC: F42C15/40
Filed: 1989-12-05
Abstract: A helical spring (8) is inserted between a conical bolt (2) and a threaded stopper (1a) in a suitably shaped bore (1) into the housing (7) of a rotary detonator carrier (6). An electrically insulated pole pin (10) projects into a smaller bore (12) from the  detonator (9).
