摘要： A shaft assembly for movement of an array of adjustable members comprises a hollow shaft body including a shaft body wall with a wall outer surface. A plurality of spaced apart clevises, secured with the shaft body wall on the wall outer surface, each includes connection means disposed away from the wall outer surface for connection with an actuator for movement of the adjustable members.

摘要： A rotor disk includes a rim with axially spaced apart forward and aft ends, with the aft end having a larger diameter than the forward end. The rim includes a plurality of straight dovetail slots defining dovetail posts therebetween. Each dovetail post includes a pair of lobes, a neck, and first and second pressure faces facing radially inwardly from the lobes. The first and second pressure faces vary in radial height therebetween from a first magnitude at the rim aft end to a second and smaller magnitude at the rim forward end to shift a portion of the bending loads from the dovetail post at the rim forward end to the dovetail post at the larger rim aft end.

摘要： A sealing device for compressor axial dovetail rotor blades for a gas turbine engine comprising a sealing member having a finger portion extending from a main body portion which engages a disk hook located on each disk post and forms a first point of contact about which the sealing member rotates. The sealing member further comprises an extended skirt portion which engages the blade platform of the rotor blades forming a second point of contact. The main body has a center of gravity positioned such that during operation of the engine the main body pivots due to centrifugal force about the disk hook such that the skirt portion engages the blade platform. A split ring is located between the disk posts and a tail portion extending from the lower portion of the sealing member and engages the disk post and tail portion during operation of the engine thereby forming a third point of contact. The combination of the skirt element contacting the blade platform and the split ring contacting the tail portion and the disk posts effectively prevents any leakage axially through the rotor blade dovetail.
