Patent ID: 8037799

Claim:
A system comprising: a housing; a plurality of electromagnetic coil layers within the housing, the plurality of electromagnetic coil layers concentrically arranged about a central axis of the housing such that a first concentric electromagnetic coil layer is proximate to an inner shell of the housing, such that a second concentric electromagnetic coil layer is proximate to an outer shell of the housing, and such that a third concentric electromagnetic coil layer is positioned between the first concentric electromagnetic coil layer and the second concentric electromagnetic coil layer, wherein the first concentric electromagnetic coil layer is positioned at a first distance from the central axis, the second electromagnetic coil layer is positioned at a second distance from the central axis, and the third electromagnetic coil layer is positioned at a third distance from the central axis, wherein the first distance is less than the third distance, and the third distance is less than the second distance, wherein the plurality of electromagnetic coil layers is vertically arranged to form one or more coil stacks; a plurality of thermal dampers positioned between the electromagnetic coil layers, the plurality of thermal dampers concentrically arranged about the central axis of the housing, the thermal dampers comprising one or more of steel and aluminum; and a thermal structural plate positioned between a bottom portion of a first coil stack and a top portion of a second coil stack; wherein the system comprises an electromagnetic projectile launching system.
