| Abstract: | A classical two-dimensional, bending-torsion flutter analysis of a reference airfoil in a cascade of infinite blades is performed. The unsteady airloads on the reference airfoil are predicted using a numerical lifting surface theory. Several cascade and flow parameters such as inter-blade spacing, stagger angle, phase angle between blades, Mach number, and frequency are investigated. The bending-torsion flutter speed of the cascaded reference airfoil is studied as a function of the cascade and flow parameters and the results are compared with that of an isolated airfoil. |
