ABSTRACT:
A fuse for an explosive shell comprises a body having a longitudinal axis, a hood unit fitting over the body and movable along the body vertical axis between a first position and a second position, and a parachute linked to the hood unit for pulling the hood unit from its first position to its second position when the explosive shell is released. A slide catch is housed in the body and is moveable in a direction perpendicular to the body perpendicular axis from an unprimed to a primed position. A primary detonator is housed in the slide catch. The primary detonator is out of alignment with the main charge of the explosive shell when the slide catch is in its unprimed position, and is in alignment with the main charge of the explosive shell when the slide catch is in its primed position. A safety catch holds the slide catch in its unprimed position until it is released by inertial forces acting on the fuze. A firing pin detonates the primary detonator. The firing pin has an upper portion fixedly housed in the hood unit and a lower portion slidably housed in the body. The lower portion is moveable along the body longitudinal axis between a first and a second position in response to the movement of the hood unit between its first and second positions.
