Collateral Cavity Electromagnetic Propulsion Guns

Abstract

Narrow collateral cavity electromagnetic guns with two wall conductor assemblies with a divide plane proximal barrel bus and array of wall conductors extending therefrom to contact means proximal the half cavity's narrow wall in each collateral cavity half, like potential power rails at the narrow walls and a midline power rail in a wall there between. Each collateral half of projectiles for use therein have: a propulsion bus orthogonal the cavity's axis continuous the said midline power rail at one end and propulsion bus-aft shunt current bus the other, and forward and aft current shunts on both sides of the projectile's collateral halves. Projectile's current buses co-act with said assembles, shunts and power rails circulating the gun's current around both sides of the propulsion buses and the magnet fields of said circuit interact with the propulsion buses' currents creating forces therein propelling the projectile through the barrel cavity.

No. 11 / 306,245 filed Dec. 20, 2005.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The following invention is related electromagnetic propulsion devices such as rail guns. In rail guns a magnetic field perpendicular to an electrical current path through an armature, interacts with the path current, creating force on the armature which is perpendicular to both the current path and the magnetic field. The armature of a rail gun is located between and has ele...

Benefits of technology

[0016] The collateral barrel cavity of the topic invention and the projectiles used therein eliminate the above said losses due to friction by utilizing like, but oppositely directed forces of attraction between the current buses in each collateral half of a projectile and their proximal power rail which cancel each other and the need of additional barrel rails and their attendant sliding continuities to avoid said loss generating force is eliminated.

Problems solved by technology

These devices, although more cumbersome, permits more latitude in accelerator design.
