Abstract:
In a closely spaced, coaxial counter-rotating (CCR) rotor, the passage of upper and lower rotor blades over each other results in transient loads and blade deformation. This paper describes the measurement and numerical modeling of these transient loads and blade deformations in a single-bladed, 2-m-diam, rigid CCR rotor system in hover. Three-dimensional rotor blade deformation was measured using a time-resolved digital image correlation technique, simultaneously with the rotor thrust and pitch...     »
