Filed:

Jul 16, 2004

Appl. No.:

10/895473

Inventors:

Michael K. Oetjen - Alexandria VA, US
Robert V. Krueger - King George VA, US
Raymond D. Cooper - Bowling Green VA, US

International Classification:

F41A 17/00

US Classification:

89 11, 89 9, 89 2712, 42 101, 42 105, 42 6901, 340584

Abstract:

Determining cook-off time for a weapon is disclosed. A method determines a first barrel temperature next to a first energetic, such as a propellant charge, of ammunition within a gun barrel, and determines a second barrel temperature next to a second energetic, such as an explosive charge, of the ammunition. If the ammunition did not properly fire, the method determines a first cook-off time of the first energetic based on the first temperature next to the first energetic and the first energetic's type, and a second cook-off time of the second energetic based on the second temperature next to the second energetic and the second energetic's type. The first and second times may be determined by using one or more finite-difference heat transfer models. If either or both of the first and second times are less than a threshold, a warning-related action is performed to users of the weapon.

International Classification:

US Classification:

Abstract:

An improved rotating band for a projectile is disclosed. The rotating band omprises a plastic sleeve, two micarta inserts, and a retainer ring. One micarta insert, located in the middle of the plastic sleeve, contains grooves which increase the friction coefficient and elasticity of the rotating band. The second micarta insert, located further forward, provides additional barrel contact area. These improved characteristics enable the projectile to be retained in a hot gun when elevated or rammed at any velocity. A retainer ring is molded onto the aft end of the plastic sleeve to secure the invention to the projectile. The rotating band also acts as a seal and spins the projectile as it moves through the gun barrel. The rotating band disintegrates after the projectile exits the gun barrel.
