INTERNATIONAL AEROSPACE INSTRUMENTATION SYMPOSIUM (4TH) PRESENTATION ON THE MEASUREMENT AND ANALYSIS OF ROTOR BLADE AIRLOADS AND THE RESULTING DYNAMIC RESPONSE OF A LARGE TANDEM ROTOR HELICOPTER

Abstract

A highly instrumented tandem rotored helicopter has been flight tested to obtain rotor airload pressures, rotor blade bending, rotor hub motions, rotor shaft and control loads and the resulting fuselage vibration. These data were recorded in flight on magnetic tape and ground processed using an analog to digital converter and extensive computer analyses. The systems and procedures utilized included extensive interaction calibration corrections. Analyses to determine the accuracy of the data have been developed to compare redundant but independent measurements. The results were prepared for review, analysis and further consideration with the aid of automatic plotting equipment.
