IMPROVED BLADE FLAPPING MEASUREMENT PROCESS

A rotorcraft (10) comprising a rotor blade (26a) designed to flap about a hinge point, a measurement system (200) designed to measure blade flapping, and a processing system (300) designed to alter blade flapping measurements. The processing system further comprises a correction process to alter a b...

Zusammenfassung:	A rotorcraft (10) comprising a rotor blade (26a) designed to flap about a hinge point, a measurement system (200) designed to measure blade flapping, and a processing system (300) designed to alter blade flapping measurements. The processing system further comprises a correction process to alter a blade flapping measurement dependent on rotor RPM or rotor torque.
