Abstract: A compressor stator vane for a gas turbine engine comprised of a leading edge section and a trailing edge section and constructed so that either or both sections may be rotated about a common axis of rotation to vary vane camber with torque for rotating the sections being applied around the engine perimeter.

Abstract: A film squeeze damper for a thrust bearing includes a plurality of curved beam segments each having a fluid chamber adjacent the support housing and mounted end to end to surround the thrust bearing. Side mounted nibs transmit the thrust load from a radial dependent member of the outer race to the support housing through each segment. This permits unrestrained radial damping of vibratory energy occasioned by the unbalance in the supported shaft. A mechanical stop is provided by the design to limit radial deflection of the segment during a high rotor unbalance.

Abstract: A flow attenuator which is utilized to direct coolant flow to liquid cooled laser mirrors and in so doing substantially eliminates the liquid flow induced jitter generally associated with such flow. The flow attenuator has a housing in which is formed a centrally located passageway. The passageway branches into a plurality of substantially radially extending contoured chambers. A distribution screen is removably interposed between the passageway and the chambers in order to substantially reduce the "noise" within the coolant liquid as it passes through the attentuator to the laser mirrors.
