    摘要: A high aspect ratio, low solidity fan blade of an axial flow air cycle machine has a local tip center of gravity axis that has been shifted ahead of an elastic axis. The center of gravity axis can be shifted by clipping the tip of the blade at the trailing edge, by undercutting a rear portion of the pressure surface, or by sweeping forward leading and trailing edges of the blade by about five degrees (without clipping or undercutting the blade).

    摘要: A system and method for reducing blade strain on the fan blades of an air cycle machine is proposed. The method involves a strut arrangement that is positioned in a cylindrical air passage upstream from the fan assembly. The strut arrangement includes at least three struts, wherein the at least three struts are separated by unequal degrees of separation along the circumference of the air passage. The strut arrangement effectively reduces the strain on the blades of the fan assembly.

    摘要: An inner sleeve, having threads on each end, is formed on a motor or generator rotor. A pair of stub shafts are threadably attached to the inner sleeve at each end and a magnet is placed in between. The stub shafts are turned on the inner sleeve to bring them together, thereby creating an axial compressive force on the magnet. By keeping the magnet in a compressive state at all times, cracking of the magnet is prevented, thus keeping the rotor stable during use of the motor or generator. An outer sleeve is shrunk-fit around the magnet and stub shafts to provide a further radial force on the rotor. The magnet assembly of the present invention also enlarges the required radial shrink-fit tolerance of the outer sleeve on the magnet, thereby reducing costs conventionally required to match the outer sleeve to the magnet within close tolerances.

    摘要: A composite resilient mount for rolling element bearings, comprising a composite hoop portion, and including a plurality of circumferentially dispersed inner pads and outer pads defining a plurality of arcuate beam portions disposed circumferentially between adjacent pads. The hoop portion and the inner and outer pads, may comprise a circumferentially wound fiber, such as a carbon fiber, and a resin. The inner and outer pads may be rounded, feathered or otherwise configured to eliminate edges from the inner and outer pads, thereby preventing damage to adjacent components. A method for providing damping to a rolling element bearing is also disclosed.
