Claims
- 1. An explosive device comprising a housing having a cavity formed therein and including a plurality of ventillation ports for the cavity,
- a movable sleeve normally covering a sealing said ventillation ports, and
- a desensitized liquid explosive contained within said cavity, the desensitizing constituent of said liquid explosive being a volatile solvent absorbed therein,
- whereby upon movement of said sleeve and uncovering of said ventillation ports said volatile solvent is allowed to evaporate and thus render said solvent desensitized liquid explosive sensitive, thereby arming said explosive device.
- 2. An explosive device as specified in claim 1 wherein the desensitized liquid explosive is contained within a porous solid matrix.
- 3. An explosive device as specified in claim 2 wherein said housing is cylindrical in shape and said ventillation ports are distributed about the housing both axially and circumferentially.
- 4. An explosive device as specified in claim 3 wherein said housing is formed in the nose of a projectile and further including a shear pin through said housing and said sleeve that normally holds said sleeve in covering relation with said ventillation ports whereby inertia forces generated by launch acceleration of the projectile are adapted to shear said shear pin and permit the sleeve to move and thereby uncover said ventillation ports, and whereby rapid motion of the projectile through the air is adapted to cause a forced loss of said volatile solvent from the solvent desensitized liquid explosive thereby to render the latter impact sensitive during the flight of the projectile.
- 5. An explosive device as specified in claim 2 wherein said housing is cylindrical in shape and is comprised of a plurality of axially separated segments, a first of one of said segments being formed in the nose of a projectile, said first one segment having said ventillation ports formed therein and containing said solvent desensitized liquid explosive, a second and adjoining segment containing a booster explosive charge, and a third segment adjoining said second segment containing a main explosive charge.
- 6. An explosive device as specified in claim 5 further including a shear pin through said housing and said sleeve and wherein said housing comprises the forward portion of a projectile, said sleeve normally being held in covering relation to said ventillating ports by said shear pin whereby inertia forces generated by launch acceleration of the projectile are adapted to shear the shear pin and permit said sleeve to move rearward, thus uncovering said ventillation ports, whereby the motion of the projectile through the air is adapted to cause a forced loss of said volatile solvent from the solvent desensitized liquid explosive, thereby to render said liquid explosive impact sensitive during the flight of the projectile, and whereby target impact is adapted to detonate the sensitized liquid explosive, which in turn, is adapted to detonate the booster explosive charge in said second housing segment, the booster explosive charge, in turn, being adapted to detonate the main explosive charge.
- 7. An explosive device as specified in claim 1 wherein the desensitized liquid explosive is selected from the group consisting of
- liquid hydrocarbons containing "nitrato" group(s), e.g. ##STR4## Liquid hydrocarbons containing "nitramine" groups ##STR5##
- liquid hydrocarbons containing "nitro" groups ##STR6## and admixtures thereof, and wherein the desensitizing constituent of said desensitized liquid explosive is a solvent selected from the group consisting of hydrocarbons, halocarbons and admixtures thereof.
