Article publication date: 1 July 1940
THE calculation of the natural frequencies of oscillation of an articulated rotary‐wing system presents considerable difficulty owing to the large number of variables which require to be taken into account and it is proposed to consider first of all the simplified system of a mass rotating about a fixed axis and connected to it through two hinges, the axes of which are inclined to one another but lie in parallel planes perpendicular to the arm connecting the two hinges. In the next article an approximate method will be given of obtaining the natural vibrations of an articulated rotary‐wing system.
