Abstract

The most vital system of a rotorcraft is the rotor system due to its effects on the overall flight quality of the vehicle. Therefore, it is of importance to be able to accurately determine blade position during flight so that fine adjustments can be made to ensure a safe and efficient flight. In this study, a current calibration method focusing on the pitch, flap, and lead-lag blade angles is analyzed and found to have larger than acceptable error associated with the sensor calibrations. A literature review is conducted which reveals four novel methods that can potentially increase the accuracy of the sensor calibrations. An uncertainty analysis is conducted aiding in the decision of which of the four methods would best improve the calibration accuracy. The results conclude that a simpler method can be applied and calibration times can greatly be reduced while increasing the accuracy of the calibration. Finally, a new calibration method is proposed utilizing the newly chosen sensor that can be later implemented into the system.
