US12578174 - Curve of constant width projectile system

The patent describes a projectile system featuring a projectile and propellant charge designed with a cross-section shaped as a curve of constant width, which enhances aerodynamic properties. The barrel of the launching device is also configured to match this unique cross-sectional shape, optimizing the projectile’s performance during launch.

Claim 1

1 . A projectile launching system, comprising a projectile, a propellant charge, a barrel wherein the propellant charge and the projectile are arranged with a cross-section in shape of a curve of constant width, wherein the curve of constant width is defined by the expression a propellant charge, a barrel wherein the propellant charge and the projectile are arranged with a cross-section in shape of a curve of constant width, wherein the curve of constant width is defined by the expression wherein the curve of constant width is defined by the expression r ⁡ ( φ ) = D 2 + C 2 ⁢ sin ⁡ ( n ⁢ φ ) , where D is the core diameter, C is the rotation diameter, φ is an angle and n is an odd integer, and wherein the barrel has an inner shape with a matching curve of constant width. where D is the core diameter, C is the rotation diameter, φ is an angle and n is an odd integer, and wherein the barrel has an inner shape with a matching curve of constant width.
