Winter 1997 Seminar Series


Modeling Rotorcraft Flight Dynamics



Professor H.C. Curtiss

Princeton University
Department of Mechanical and Aerospace Engineering


Abstract

As an introduction, some remarks about the historical development of helicopters and the evolution of the modern helicopter and its control system will be made. There will also be a discussion of the evolution of stabilization and automatic flight control systems for helicopters. Various problems encountered in the development of new rotorcraft will be described. Important issues related to accurate modeling of the control response of helicopters will be considered in some detail including the influence of the rotor system dynamics on the design of flight control system . Recent work on the importance of various aerodynamic model assumptions on prediction of the response to control will be described and areas for future investigation discussed.
