Electrical Ignition of Rocket Engines and Motors 630257
Ignition systems are categorized into two general groups: one producing energy in short high power bursts and the other in long low power bursts. Capacitor discharge systems for jet engines and exploding bridge wire type of initiators are of the first group. Constant current transformers and induction vibrators, producing high tension, glow plugs and hot wire initiators utilizing primary power directly are in the second group.
Methods of control, advantages and limitations, and susceptibility to external stimuli are compared with emphasis on electro-magnetic compatibility. Capacitor discharge systems for exploding bridge wire initiators are particularly emphasized because of their increasing use on missiles.
