Abstract
An actuator rod assembly for a blade pitch control system is provided herein. The actuator rod assembly includes a tubular outer rod and an inner rod. The outer rod has a first end and a second end. The inner rod has a first end and a second end and extends through the tubular outer rod. The inner rod is tensioned against the tubular outer rod so as to place the outer rod in compression.
Claims15
An actuator rod assembly for a blade pitch control system comprising:
- a tubular outer rod with a first end and a second end;
- an inner rod, with a first end and a second end, extending through the tubular outer rod;
- wherein the inner rod is axially tensioned against the outer rod so as to place the outer rod in axial compression;
- and
- an indicator washer frictionally clamped in a load path between the inner and outer rods, so as to be rotationally fixed when the inner rod is tensioned and rotationally released when the tension is lost due to failure of the inner rod.
