Projection Moiré Interferometry for Rotorcraft Applications: Deformation Measurements of Active Twist Rotor Blades

Abstract

1 Projection Moiré Interferometry (PMI) has been used during wind tunnel tests to obtain azimuthally dependent blade bending and twist measurements for a 4-bladed Active Twist Rotor (ATR) system in simulated forward flight. The ATR concept offers a means to reduce rotor vibratory loads and noise by using piezoelectric active fiber composite actuators… (More)
