Design of helicopter rotor blades
WebA helicopter rotor blade is usually mounted on a set of hinges which allow three angular degrees of freedom. A typical arrangement of the hinges is shown in Fig. 1.The flapping motion is defined as an up and down rotation, through an angle β, in a plane which contains both the blade and the shaft.This angle is considered positive when the blade flaps … http://dymoresolutions.com/resume/Presentations.html
