Unison ring actuator assembly. |
摘要 |
<p>An actuator assembly for imparting non-proportional tangential displacement (22b) to a plurality of unison rings (16b, 16c) disposed about the exterior of a compressor case (10b) is provided. The assembly includes a linear drive component (26b) mounted on trunnions (74,76) and supported by a frame 48. The drive component (26b) imparts a rotating motion to a crankshaft 70 which in turn drives the unison rings (16b, 16c) via the respective crank arms (42b, 42c) and pushrod (30b,30c) linkages. Radial loading of the compressor case (10b) is avoided by aligning both the pushrod (30b) and an elongated frame end (50) tangential to the compressor case (10b).</p> |
