US12422232 - Bullet system with multiple drag-reducing capabilities

The patent describes a bullet system designed to reduce various types of drag during flight, incorporating three distinct drag-reducing assemblies that work in conjunction. These assemblies include features such as a cavity for additional propellant and a vapor discharge mechanism to enhance aerodynamic performance.

Claim 1

1. A bullet system for use with a cartridge for propelling out from a barrel of a weapon upon firing, the bullet system comprising: a main body acting as a projectile; a first drag-reducing assembly provided about a rearward portion of the main body, for providing the bullet with a reduction of base drag during flight trajectory, the first drag-reducing assembly includes a cavity being disposed within the rearward portion of the main body, the cavity of the first drag-reducing assembly being positioned, shaped and sized for receiving and for containing therein additional propellant to that of the cartridge; a second drag-reducing assembly provided about a frontward portion of the main body, for providing the bullet with a reduction of frontal drag during flight trajectory; and a third drag-reducing assembly provided about an internal portion of the main body, for providing the bullet with a reduction of skin drag during flight trajectory, the drag-reducing assemblies being fluidly connectable to one another via at least one corresponding channel, and at least one of said drag-reducing assemblies being provided with a material capable of being converted into an operative vapor discharge to be released from a corresponding orifice of the main body of the bullet system for covering the main body of the bullet system with said operative vapor discharge during flight, and thus, reducing an associated skin drag of the bullet system during flight. a main body acting as a projectile; a first drag-reducing assembly provided about a rearward portion of the main body, for providing the bullet with a reduction of base drag during flight trajectory, the first drag-reducing assembly includes a cavity being disposed within the rearward portion of the main body, the cavity of the first drag-reducing assembly being positioned, shaped and sized for receiving and for containing therein additional propellant to that of the cartridge; a second drag-reducing assembly provided about a frontward portion of the main body, for providing the bullet with a reduction of frontal drag during flight trajectory; and a third drag-reducing assembly provided about an internal portion of the main body, for providing the bullet with a reduction of skin drag during flight trajectory, the drag-reducing assemblies being fluidly connectable to one another via at least one corresponding channel, and at least one of said drag-reducing assemblies being provided with a material capable of being converted into an operative vapor discharge to be released from a corresponding orifice of the main body of the bullet system for covering the main body of the bullet system with said operative vapor discharge during flight, and thus, reducing an associated skin drag of the bullet system during flight.
