Abrégé

A bullet system (1) for use with a weapon upon firing, the bullet system (1) including a main body (3) acting as a projectile, as well as a first, second and third drag-reducing assemblies (5a, 5b, 5c) for providing the bullet system (1) with reductions of base drag, frontal drag and skin drag, during flight trajectory, the drag-reducing assemblies (5a, 5b, 5c) being fluidly connectable to one another via a common longitudinal channel (11), and the most frontward (5b) of said drag-reducing assemblies (5a, 5b, 5c) being provided with a material capable of being converted into an operative vapor discharge to be released from an orifice located at the bullet tip for covering the outer surface of the main body (3) of the bullet system (1) with said operative vapor discharge during flight, and thus, reducing the skin and frontal drag of the bullet system (1) during flight; wherein the first drag-reducing assembly (5a) is being provided about a rearward portion of the main body (3) for providing the bullet (1) with a reduction of base drag during flight trajectory.

Abrégé

A bullet including a drag-reducing assembly provided about its main body, and configured for being triggered upon a blast from a cartridge, in order to reduce a resulting base drag of the bullet during flight trajectory. The drag-reducing assembly includes at least one cavity being configured for receiving and containing a portion of gun gas from the cartridge and corresponding blast, and at least one peripheral orifice for releasing gun gas from the at least one cavity during the flight trajectory of the bullet, in order to fill a partial vacuum behind the bullet during flight trajectory, and thus reduce the resulting base drag, for an improved overall ballistic performance of the bullet.

Abrégé

The present disclosure concerns a bullet (1) configured to be propelled by a blast of a cartridge, the bullet comprising a main body (3) provided with an internal body cavity (7) and having a frontward section and a rearward section provided with an opening in fluid communication with the internal body cavity, the internal body cavity by means of the opening being capable of recovering a portion of gun gas resulting from the blast of the cartridge. The present disclosure further comprises a weapon having such a bullet, and a method for reducing drag from a bullet propelled out of a barrel of a weapon.
