Abstract
A fin-stabilized projectile suitable for launching from a shotgun or similar weapon. The projectile may penetrate easily breakable materials but will not penetrate tougher materials. The projectile may be shot through an easily breakable surface to gain entry to a target location, but further penetration is inhibited. The projectile is equipped with an on board sensor. The halves of the projectile casing form a dipole antenna for transmitting information gathered by the on board sensor.
Claims18
A projectile, comprising:
- a hollow conductive casing comprising a forward section and a rear section;
- an insulating ring being disposed between the forward section and the rear section to insulate, electrically, the forward section from the rear section,
- wherein the forward section and the rear section comprise a dipole antenna, and
- radio frequency electronics connected to at least one sensor and the dipole antenna for transmitting information provided by said at least one sensor to a receiving location,
- wherein the forward section includes a soft, ductile material adjacent a relatively hard, dense material.
A projectile, comprising:
- a hollow casing comprising a forward section;
- a tail fin being disposed on an aft end of the hollow casing;
- an axial rod being disposed on a longitudinal axis of the projectile, one end of the axial rod protruding outwards from a forward section of the hollow casing and another end of the axial rod connecting to the tail fin;
- and
- radio frequency electronics being connected to at least one sensor and a dipole antenna for transmitting information being provided by said at least one sensor to a receiving location,
- wherein the forward section includes a soft, ductile material adjacent a relatively hard, dense material.
