Aircraft Brakes
Aircraft brakes typically are made with a stack of alternatively interleaved stator and rotor discs, the discs being adapted for selective factional engagement with one another. The stator discs are typically splined to the axle of the aircraft, while the rotors are keyed to the wheel, generally by a series of beam keys that are circumferentially spaced about an inner portion of the wheel and that engage key slots in the outer circumferential surface of the rotors. The beam keys typically have one end thereof pinned to the wheel and an opposite end thereof mounted to an outrigger flange of the wheel.

Molding systems and processes
Advani, Devillard and Lawrence of the University of Delaware has developed a resin transfer molding system which the flow of resin to different parts of the mold can be selectively controlled. This is based a mold plate containing a network of resin paths controlled by injection gates open and closed by a deformable part. (RDC 11/4/2010)
