A full-scale helicopter smart material actuated rotor technology (SMART) rotor test was conductedin the USAF National Full-Scale Aerodynamics Complex 40- by 80-Foot Wind Tunnel at NASAAmes. The SMART rotor system is a five-bladed MD 902 bearingless rotor with active trailing-edgeflaps. The flaps are actuated using piezoelectric actuators. Rotor performance, structural loads, andacoustic data were obtained over a wide range of rotor shaft angles of attack, thrust, and airspeeds.The primary test objective was to acquire unique validation data for the high-performancecomputing analyses developed under the Defense Advanced Research Project Agency (DARPA)Helicopter Quieting Program (HQP). Other research objectives included quantifying the ability ofthe on-blade flaps to achieve vibration reduction, rotor smoothing, and performance improvements.This data set of rotor performance and structural loads can be used for analytical and experimentalcomparison studies with other full-scale rotor systems and for analytical validation of computersimulation models. The purpose of this final data report is to document a comprehensive, highqualitydata set that includes only data points where the flap was actively controlled and each of thefive flaps behaved in a similar manner
