Abstract: CAMBER-MORPHING ROTOR BLADE ASSEMBLY WITH CENTRIFUGAL ROOT WEIGHING AND SLIDER-DRIVEN CYCLIC-STRAIN SHEDDING OF ACCRETION A camber-morphing rotor blade assembly (100) has a blade (110) with a spar (112), a compliant skin (114) and chordwise bilaminar flexure members (120) whose laminae slide relative to each other at the spar to bend the skin. A slider (130) in the spar imposes the sliding through cam surfaces and is moved by a non- rotating actuator (160). The blade is carried on the hub (102) by a radially compliant root mount (140) that moves 0.20 mm to 1.0 mm under centrifugal load at maximum speed. A non-rotating sensor (150) reads this displacement each revolution; a controller (170) divides it by the square of the speed to weigh the accretion and, above a threshold, drives the same slider in a cyclic shed mode whose amplitude is set from the weighed mass. Rolling cam followers, a reference target and a temperature-calibrated stiffness map keep friction and drift out of the weighing. FIG. 1
