Propeller disk projectile

A spin-fired projectile for use against enemy aircraft which comprises:

• an ogival shaped member having a pointed forward end, a threaded rear end boss, an axially positioned propellant charge counterbore located in said threaded rear end boss, and a plurality of rod holes disposed in said threaded rear end boss;
• a propellant charge operatively positioned in said propellant charge counterbore;
• a time fuze disposed in said forward end of said ogivally shaped member, said time fuze communicating with said propellant charge;
• a propellant charge sealing disk member located in said propellant charge counterbore for retaining said propellant charge in said propellant charge counterbore during assembly of said projectile;
• a cylindrically shaped tubular body member having an internally upper end threaedly connected to said threaded rear end boss of said ogival member and an internally threaded lower end;
• a piston member having a plurality of piston rod holes therein slidably positioned in said tubular body member adjacent said ogival member rear end boss, said piston member being movably responsive to gases generated by said propellant charge;
• propeller disk fragment means, transversely slidably disposed and stacked within said tubular body member for presenting a momentarily standing, ascending or descending fragment cloud effective against said enemy aircraft when being ejected from said tubular body member;
• a threaded rear end member threadedly affixed to said lower end of said tubular body member having an annular groove therein, said threaded rear end member retaining said propeller disk fragment means within said spin-fired projectile during transportation to a target, said threaded rear end member separating by shear from said lower end of said tubular body member when said time fuze initiates said propellant charge, forcing said piston member in a rearward direction and said propeller disk fragment means against said rear end member.
