DEVELOPMENT AND EVALUATION OF 6-COMPONENT LOAD CELL FOR LAND-BASED TEST OF HELICOPTER ROTOR DYNAMICS
Abstract
A 6-component force transducer was developed and evaluated for small-scale model test of helicopter rotor dynamics. The evaluation of the transducer was done mainly through interference check using multi-component calibration procedures. In this paper, the design and analysis process and the related results are verified through calibration results. The force transducer was designed to fix to rotating hub, and dominant force component was lifting force with maximum 1000 lb. From rotating characteristics, fail-safe structure was required to prevent the rotor from bursting out in case of rotor failure. The sensing element was designed with structural symmetry for selfcompensation by full bridge circuit and the expected deformation was analyzed by using finite element method.
