Abstract
A full three-dimensional lifting surface theory based on the double linearization concept is developed for a rotating annular cascade model operating at axial supersonic velocity. It is assumed that each blade vibrates with infinitesimal displacement amplitude under small mean loading. Vibration modes normal and parallel to the blade chord are considered. Numerical results are presented to investigate the steady loading effects on the aerodynamic instability of the blade motion. It is found that the bending motion can be unstable due to presence of the mean loading. Some numerical results compared with strip theory predictions demonstrate significant three-dimensional effects on the unsteady aerodynamic force.
