US12638279 - Projectile with a tapered structure within a forward cavity

A projectile comprising a bullet slidably mounted within a cartridge, which includes a propellant to propel the bullet when fired. The bullet features a head section and a trailing section located aft of the head section. The head section comprises one or more side walls defining a cavity with an opening at the leading end of the bullet. A tapered structure secured to the trailing section extends into the cavity, tapering in a fore direction towards the central longitudinal axis of the bullet. Upon impact with a target, the one or more side walls are configured to break away from the trailing section, and the tapered structure reduces drag and pressure build-up in the trailing section, allowing for greater penetration capabilities.

The patent describes a projectile design featuring a bullet with a tapered structure within a cavity that enhances penetration by reducing drag and pressure build-up upon impact. The innovative design allows the bullet’s side walls to break away from the trailing section, improving its performance when striking a target.

Claim 1

1 . A projectile comprising: a bullet slidably mounted within a cartridge, the cartridge having a propellant, wherein the bullet includes a head section and a trailing section located aft of the head section; the head section comprising one or more side walls defining a cavity and an opening in a leading end of the bullet leading to the cavity; a tapered structure secured to the trailing section and extending into the cavity, wherein the tapered structure tapers in a fore direction towards a central longitudinal axis of the bullet; wherein the one or more side walls are configured to break away from the trailing section after impact with a target; wherein the tapered structure is configured to reduce drag and pressure build-up in the trailing section of the bullet after the one or more side walls have broken away from the bullet, allowing for greater penetration capabilities. a bullet slidably mounted within a cartridge, the cartridge having a propellant, wherein the bullet includes a head section and a trailing section located aft of the head section; the head section comprising one or more side walls defining a cavity and an opening in a leading end of the bullet leading to the cavity; a tapered structure secured to the trailing section and extending into the cavity, wherein the tapered structure tapers in a fore direction towards a central longitudinal axis of the bullet; wherein the one or more side walls are configured to break away from the trailing section after impact with a target; wherein the tapered structure is configured to reduce drag and pressure build-up in the trailing section of the bullet after the one or more side walls have broken away from the bullet, allowing for greater penetration capabilities.
