Abstract

A fuse device for a mortar shell includes an impact weight carrying a detonation charge and arranged to impact against a firing pin when the mortar shell strikes a target. A safety arm locks the impact weight against movement toward the firing pin in a safety position. The safety arm is movable out of locking relationship with the impact arm to establish an armed condition of the fuse device. Energy for moving the safety arm is stored in a spring. That energy is stored after the mortar shell has been launched, because an impeller is rotated by an air flow generated by the moving mortar shell, and that impeller rotation is transmitted to the spring to store energy.
