Abstract
A practice ammunition device, particularly a practice mortar shell, corresponding substantially identically to a live, tactical mortar shell in size, weight, configuration, and location of center of gravity. The practice shell closely simulates a live shell in all phases of operation including handling, loading, trajectory, and impact.
Claims10
A practice shell comprising an outer casing;
- tubular means mounted coaxially within and spaced from said casing substantially throughout its length;
- cementitious ballast means substantially filling the space between said casing and tubular means, said cementitious ballast means being of suitable composition so that, when mixed with water, it sets up rapidly between said casing and tubular means, it develops high early strength, and it expands upon setting to substantially completely fill the space between said casing and tubular means;
- a nose assembly connected to the forward end of said tubular means;
- a firing pin assembly mounted within said nose assembly;
- and a signal device mounted within said tubular means and adapted to be detonated by said firing pin assembly upon impact of said nose assembly with a target.
2 more elements
A practice mortar shell comprising an outer casing, tubular means mounted coaxially within and spaced from said casing, said tubular means having forward and rearward ends extending beyond the ends of said casing;
- cementitious ballast means substantially filling the space between said casing and said tubular means, a nose assembly threadedly connected to the forward end of said tubular means, a firing pin assembly housed within said nose assembly, a signal device mounted within said tubular means and adapted to be detonated by said firing pin assembly upon impact of said nose assembly with a target, a tailpiece assembly, frangible thread means connecting said tailpiece assembly to said rearward end of said tubular means and adapted to release said tailpiece assembly from said tubular means upon detonation of said signal device, said tailpiece assembly including charge propellant means and a rear fin assembly for propelling and guiding a shell in use.
