Abstract: The magnitude of the perturbations to the steady-state rotation of most mechanisms is difficult to control with present methods. This paper shows an alternative method of reducing the magnitude ...

Abstract: The stability of hydrofoils is currently estimated by plots of the log decrement versus flutter frequency and forward speed. Herein is suggested a method used by electrical or electronic engineers ...

Abstract: A theory is given for the determination of the flutter frequency and speed of a hydrofoil traveling at a constant speed. This work used the work of Sears to determine the fluctuating lift ...
