Abstract
Official abstract text for this publication.
A dynamic rotor-phasing unit can phase rotors in-flight for dynamic rotor tuning and in an idle state for aircraft storage. The input and output shafts can be clocked (e.g., rotated) from 0 degrees apart to in excess of 360 degrees apart or from 0 degrees apart to 140 degrees apart. Such rotation can minimize the footprint of an aircraft for stowing purposes, as the rotor blades can be folded to fit within a smaller area without disconnecting the drive system. Additionally, the unit can allow tiltrotor blades to be clocked during flight, which can allow the live-tuning of the aircraft's rotor dynamics. A fail-safe rotary actuator can rotate a stationary planet carrier to clock the input shaft and the output shaft. Alternatively, an actuator can position a slider housing to clock the input shaft and the output shaft.
First claim
Opening claim text (preview).
What is claimed is: 1. A slider dynamic rotor-phasing unit, comprising: a slider housing; an actuator; a common gear; and a clocking gear, wherein the actuator pulls the slider housing toward an ICDS gear to create a phasing differential between an input shaft and an output shaft. 2. The slider dynamic rotor-phasing unit of claim 1 , wherein the actuator causes the common gear to move toward or away from the ICDS gear when the actuator is activated. 3. The slider dynamic rotor-phasing unit of claim 1 , wherein the operation of the actuator causes the clocking gear to rotate above or below a plane of the ICDS gear. 4. The slider dynamic rotor-phasing unit of claim 1 , wherein the actuator telescopes. 5. The slider dynamic rotor-phasing unit of claim 1 , wherein the difference in the clocking gear mesh points from its starting position identifies the angle that the input shaft and the output shaft are clocked.
