Adjustable Electrical Time Delay Fuze

US Patent:
3967557, Jul 6, 1976
Filed:
Jan 22, 1975
Appl. No.:
5/543287
Inventors:
Charles G. Irish - Port Tobacco MD
Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
F42C 1106
US Classification:
102 702R
Abstract:
An electrical time delay fuze for exploding a projectile in air over a tat comprises (1) a battery and voltage divider carried by the gun, (2) a firing circuit carried by the projectile including two capacitors initially connected in parallel with each other to be charged by the battery, prior to firing the gun, to two different voltages, switching means for subsequently connecting the capacitors in series with each other and with a timing resistor, and means for connecting the two capacitors to the cathode, anode and gate of a programmable unijunction transister (PUT) so that, after setback and projectile launch at firing, the two capacitors discharge through the resistor until the anode is sufficiently positive to the gate to cause the transistor to discharge through an electrical detonator and explode the projectile.
