A multi-piece projectile for a small arm training ammunition round maintains stable flight until reaching transonic speeds. During transonic and subsonic flight, aerodynamic features located on the projectile generate a pressure differential to increase limit cycle motion of the projectile. The aerodynamic features are located on a portion of the projectile which does not interface with rifling elements of the gun barrel and may include protrusions in or extrusions from the projectile.

Dynamic instability reduced range round

A kinetic energy penetrator for use in small caliber ammunition, which penetrator can utilize composite material small sabots. A large shear area in the sabot having a small number of decreasingly sized buttress grooves, mate to the penetrator shaft making use of composite material sabots feasible. Lightening of the penetrator through substitution of composite material sabots results in greater velocity with higher kinetic energy on lethal impact. The fewer grooves aerodynamically lessen drag and likewise tend to boost velocity plus lethal impact.

Long rod penetrator concept for small caliber munitions

A projectile comprises an imaging seeker at a front of the projectile; a front warhead behind the imaging seeker; a power supply; an electronics unit connected to the power supply and comprising a microprocessor circuit board, a voltage regulator circuit board, an inertial measurement circuit board and a fuze and safe and arm circuit board, all electrically connected to each other, the microprocessor circuit board also being connected to the imaging seeker; a rear warhead, the front and rear warheads being electrically connected to the safe and arm circuit board; a rocket motor electrically connected to the electronics unit; foldable fins mounted at the rear of the projectile; a shell that encases the front warhead, the power supply, the electronics unit, the rear warhead and the rocket motor; and a maneuver mechanism disposed in the shell and electrically connected to the microprocessor circuit board.

Light fighter lethality seeker projectile

A statically stable limited range projectile utilizes a fin assembly combd with a cylindrical body and low drag ogival front end to ballistically match the limited predetermined range flight characteristics of a standard round.
