Boosted kinetic energy penetrator fuze
First Claim
1. In a fuze, in combination:
- a cylindrical rotor having an axis, ends, an axial bore at one end of said axis, said axial bore having an open end, a transverse bore communicating with said axial bore, said bores containing explosive leads, and a radially extending caming pin;
means supporting the ends of said rotor for rotation about said axis;
an inertia weight bored to receive said rotor and having a helical groove to receive said caming pin, so that displacement of said weight along said rotor between first and second positions causes rotation of said rotor between first and second rotated positions thereof;
and a detonator block engaging said weight to enable axial movement and to prevent rotation of said weight about said axis, said block including a radial detonator bore which is aligned with said transverse bore of said rotor in said second rotated position thereof.

Abstract
A fuze for missile having a linear axis passing rearwardly through a forward penetrator, an explosive charge with the penetrator, a fuze rearward the explosive charge, a propulsion rocket rearward of the fuze, and a canister rearward of the rocket and containing a deployable parachute, the fuze containing timers for deploying the parachute from the canister a predetermined interval after release of the missile from confinement, and for igniting the rocket a predetermined interval after deployment of the parachute, a further timer for causing discharge of the explosive charge a predetermined interval after axial impact of the penetrator with a target, and a safe-arm arrangement for preventing discharge of the explosive charge prior to the impact of said penetrator.

8. In a fuze, in combination:
-
a cylindrical rotor having an axis, ends, an axial bore at one end of said axis, a transverse bore communicating with said axial bore, and a radially extending caming pin; means supporting the ends of said rotor for rotation about said axis; an inertia weight bored to receive said rotor and having a helical groove to receive said caming pin, so that displacement of said weight along said rotor between first and second positions causes rotation of said rotor between first and second rotated positions thereof; and a detonator block engaging said weight to enable axial movement and to prevent rotation of said weight about said axis, said block including a radial detonator mounting which is aligned with said transverse bore of said rotor in said second rotated position thereof; and a shear pin normally preventing relative movement between said weight and said rotor, the mass of said weight and the size and strength of said shear pin being such that said weight shears said pin at a set impact.
