Stall-Flutter in Cascade : 2nd Report, Translatory Vibration of Cascade Blades as Treated by Semi-Actuator Disc Method, Part 2

Abstract

In the 1st report fundamental equations for calculating the aerodynamic force acting on the cascading blades vibrating in a translatory mode were given. This report shows the results of the calculation and gives the criterion for the flutter (the boundary of the region where the aerodynamic damping force cannot be negative).
