Detailed Measurements of the Aeroelastic Response of a Rigid Coaxial Rotor in Hover

Abstract

The goal of this project is to measure the performance, steady and vibratory loads, and blade deformation of a rigid, coaxial counter-rotating (CCR) rotor in hover. The modal characteristics of the blades in the rotating frame will be extracted from the blade deformation measurements. The transient loads and blade deformation occurring due to passage of upper and lower rotor blades will also be measured. These data will be useful for validation of computational models of CCR rotor systems and will yield an understanding of the physical phenomena occurring during interaction of upper and lower rotor blades.
