ANALYTICAL STUDY OF APPROXIMATE LONGITUDINAL TRANSFER FUNCTIONS FOR A FLEXIBLE AIRFRAME

Abstract

Elastic-airframe dynamics, important from the standpoint of flight control system design were studied. Approximate transfer functions are given in literal terms for three classes of vehicles. These are of such a form that the important poles and zeros are related directly to simple functions of aerodynamic, elastic, and inertial properties. The aeroelastic corrections required to account for the flexibility influences of all modes not included in the equations of motions are discussed, and a rigorous method for applying these corrections is presented.
