Patent number: 8770085Abstract: An apparatus, method and system to enhance the performance of composite armor by utilizing the energy of the threat projectile is disclosed. The frontal member includes, for example, a plurality of concentric proves on the face opposite of the surface that is impacted by a projectile. The grooves in the frontal member preferably may mate with a complimentary plurality of concentric grooves in a backing plate. During impact by a projectile, the force from the projectile presses the grooves of the frontal member into engagement with the grooves of the backing plate. The grooves are uniquely designed to cause the backing plate to impart a compressive load into the backside of the frontal member preventing it from prematurely fracturing in tension at the onset of the projectile penetration.Type: GrantFiled: September 17, 2008Date of Patent: July 8, 2014Assignee: General Dynamics Land Systems, Inc.Inventors: Steven L.

Patent number: 6604571Abstract: The invention is a method for increasing the capacity of an electrical component, such as a bus bar, to carry an electrical current. The method comprises the step of exposing the electrical component to an evaporative fluid that is in fluid and thermal contact with the electrical component. Upon heating, fluid undergoes a phase change at least partially to a vapor state. Thus, electrical energy in the form of heat generated by the flow of current is dissipated at least partially by the evaporative fluid. As a result, the temperature of the electrical component is maintained within an acceptable range when carrying the electrical current.Type: GrantFiled: April 11, 2002Date of Patent: August 12, 2003Assignee: General Dynamics Land Systems, Inc.Inventors: Ernest J.
