Abstract:

Helicopter vibration due to nonidentical inertial and aerodynamic properties of rotor blades continues to plague Army aviation maintenance personnel. This vibration manifests itself at the rotor rotational frequency, and is currently controlled through the addition of blade root and tip weights and the bending of trim tabs. Application of Individual Blade Control (IBC) offers the promise of automatically sensing this once-per-revolution (1/rev) vibration and adjusting individual rotor blade properties to alleviate the source of vibration, thus providing an automatic tracking and balancing feature for suitably equipped rotor systems. The proposed effort represents an innovative combination of recent IBC experience, a refined analytical vibration predictive capability, and a novel accelerometer-based on-blade sensing scheme to realize a practical system for prorotype design development for Army use.
