Abstract
A missile nose cone removable protective cover having a rigid outer shell of cross-linked polyethylene with a semirigid backing of polyurethane foam. A shaped linear charge is positioned in a serpentine pattern between the rigid outer shell and the foam backing. The shaped linear charge is detonated by means of a detonator in an epoxy junction box in the forward end of the nose cover.
Claims2
A protective cover for a nose cone of a missile, normally mounted external to an aircraft in captive flight, which is removable before arming and firing of the missile, comprising:
- a rigid cover of cross-linked polyethylene spaced from said nose cone;
- a semirigid backing of polyurethane foam in the space between the missile and said cover;
- a linear triangular shaped charge positioned in a pedetermined serpentine pattern between the cover and the backing;
- the apex of the triangle of said triangular shaped charge being remote from said cover;
- means for detonating said linear triangular shaped charge to thereby cut the cover to permit removal of the cover and backing by aerodynamic forces.
