Abstract: Means for mounting an engine component to the exterior of an engine's case that is mounted in an aircraft with limited access including a blind mount. The mount includes an elongated bracket fixed to the exterior of the engine case with a clevis at one end of the bracket to receive a blind mount on said engine component. Camming means operatively connected to an accessible torquing member secures the engine component in place. Hook elements on the bracket engage said engine component to allow the operator to free his hands to operate the torquing means. The mount is designed to be compatible with the existing vibratory isolation system built into the engine component.

Abstract: The present invention is a clamp with a mechanically attached grommet. The clamp secures and mounts cable, wiring, tubing, or the like to a structure. The clamp uses an outer shell, or a clamp shell, which houses a split grommet to grip the object being clamped. The grommet is mechanically attached to a low stress area in the clamp shell.

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 three dimensional converging/diverging nozzle assembly includes upstream converging nozzle flaps pivotally connected to an inner unison ring, diverging nozzle flaps pivotally connected to the downstream ends of the converging flaps, and external connectors pivotally connected at their downstream ends to the downstream ends of the diverging flaps and at their upstream ends to an outer unison ring. The outer unison ring is interconnected to the inner unison ring such that axial translation of either unison ring results in axial translation of the other unison ring, but at a different rate of speed. In one embodiment the unison rings are interconnected by a cam track and linkage arrangement.

Abstract: The upstream ends of the flaps of a variable area nozzle are pivotally connected to an axially translatable unison ring. Apparatus is associated with the flaps to cause the flaps to rotate as the unison ring is translated to vary the area of the nozzle. The unison ring includes a balance surface fixed relative thereto which is subject to a net pressure load in the downstream direction thereby reducing the force which an actuator must exert to move the unison ring or to hold the unison ring in fixed position. Preferably the balance surface is an annular surface which extends radially inwardly and has a radially inner edge to which the upstream ends of the flaps are pivotally attached.

Abstract: A variable area, three-dimensional, converging/diverging nozzle assembly includes upstream converging nozzle flaps pivotally connected at their forward ends to an axially translatable radially inner unison ring, diverging downstream flaps pivotally connected to the downstream ends of the converging flaps, and external connectors pivotally connected at their downstream ends to the downstream ends of the diverging flaps and pivotally connected at their upstream ends to a radially outer unison ring. The unison rings are interconnected such that translation of either unison ring results in translation of both the converging flaps and the external connectors. The converging flaps rotate as they are moved axially, such as by the use of a cam track and cam follower, thereby changing in the C/D nozzle exit area ratio as the unison ring translates.

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.
