Abstract
A microcomputer controlled electronic fuze capable of surviving a hard tat impact is disclosed comprising two epoxy potted printed circuit boards mounted back to back of which one of the boards is designed to survive impact and contains the microcomputer controller, storage charge, timing circuit, and fire pulse detonator circuit. The other board carries an electric motor drive circuit for mechanical timing and detonator alignment, a detonation delay command storage circuit, and an AC rectifier and voltage regulator circuit coupling a wind turbine generator power supply to the fuze.
