Abstract: The reinforced particulate aluminum metal matrix composite for brakes is used to form a brake component, such as a brake rotor, a brake coupler or the like. The composite is formed from an aluminum metal matrix reinforced with ceramic particulates. The ceramic particulates have a particulate diameter between about 0.1 and 1.0 micrometers and form greater than about 10% by volume of the reinforced particulate aluminum metal matrix composite.

Abstract: An apparatus for deicing a surface of an aircraft includes a pair of adjacent movable surface elements that lie in a common plane and cover a portion of an aircraft. The pair of surface elements are connected to a reciprocating actuator through a bell crank for reciprocal movement and in opposite directions to one another. The apparatus also includes a tie bar at one end of the surface elements for maintaining the surface elements in a parallel relationship. In a second embodiment of the invention, the apparatus includes a pair of coaxial, coplanar circular discs and a reciprocating actuator for rotating the discs in opposite directions relative to one another.

Abstract: Movable surface planes include opposed independently movable endless surfaces over the majority of opposite sides of the planes. By moving one surface in the same direction as the fluid flow about the plane, and the opposite surface in a direction opposite the fluid flow, the flow is accelerated across the surface moving in the same direction to produce a lesser pressure, and retarded across the surface moving in the opposite direction to produce a greater pressure. The net result is a force urging the plane toward the surface moving in the direction of ambient fluid flow. The two surfaces of the present invention may be operated independently of one another, to move in the same or opposite directions and to have the same or different velocities. The movable surfaces are porous and communicate with ductwork within the structure, to provide fluid flow through the surfaces for boundary layer control.
