Rotor Dynamics and Helicopter Stability: Development of a Unified Mathematical Theory of the Steady and Disturbed Motion of a Helicopter with Particular Emphasis on the Dynamical Aspects of the Problem

Abstract

SUMMARY A detailed account is given of the aerodynamic and inertia forces acting on a rotor blade when the helicopter is undergoing arbitrary disturbance in velocity and angular velocity. A fairly generalized form is used for the downwash velocity. A principle is enunciated enabling the several second order terms of significance in the angle variables to be recognized and retained.
