Tne present investigation is a continuation of a recent report by K. B. Amer on the aerodynamcc damping of a rotor with centrally arranged flapping hinges in a steady pitching or rolling motion. It considers the effect of ...
The present report deals with the frequency response of pivoted gyratory systems, and in particular, with the response of the ordinary rotor blade, the Hiller servo-blade, and the Young-Bell stabiliser to sinusoidal ...
Calculations have been made of the changes in rotor speed following engine failure on a typical helicopter in hovering flight. Various time functions for the collective pitch operation are considered. The results are in ...
