Abstract: A pylon tracking system for a tiltrotor aircraft including first and second pylons each having a pylon conversion actuator with primary and backup drive systems. The pylon tracking system includes a plurality of rotary position sensors including a first rotary position sensor coupled to the primary drive system of the first pylon, a second rotary position sensor coupled to the backup drive system of the first pylon, a third rotary position sensor coupled to the primary drive system of the second pylon and a fourth rotary position sensor coupled to the backup drive system of the second pylon. A flight control computer is in communication with the plurality of rotary position sensors and is configured to process feedback therefrom to identify a differential pylon angle between the first and second pylons during pylon conversion operations.

Abstract: Embodiments are directed to a tiltrotor aircraft having a wing, a proprotor pivotably mounted on the wing, and a downstop striker attached to the proprotor using a load pin, wherein the load pin is configured to generate an output signal representing a force between the proprotor and the wing. A downstop mounted on the wing is aligned to be in contact with the downstop striker when the proprotor is in a horizontal position. A conversion actuator moves the proprotor between a horizontal position and vertical position. A flight control computer is coupled to the output signal from the load pin and configured to control the conversion actuator, wherein the flight control computer is configured to cause the conversion actuator to increase the force if the force is less than a first selected preload value or to decrease the force if the force is greater than a second selected preload value.
