Summary

An analytical study of the flutter of stalled and unstalled propeller blades is recorded. The flutter of unstalled propeller blades investigated is unstable coupled flexural-torsional oscillation, while the flutter of stalled blades is assumed to be unstable torsional oscillation due to aerodynamical hysteresis, which is Studer's theory of stalled flutter.

A method of estimating critical speeds, which is within the scope of Stress Office work, is proposed and examples given.

The observed and calculated flutter speeds of propeller blades are tabulated.
