Tabs Reduce Helicopter-Blade Vibrations
Abstract
Tuned flaplike tab on trailing edge of helicopter rotor blade reduces blade vibration. Flapping tab on rotor blade produces aerodynamic loads that oppose vibrational aerodynamic loads. With proper choice of tab parameters, tab made to cancel much of blade vibration over wide range of rotor speeds and airspeeds.
