A Volterra Series Submodel Approach to Modelling Nonlinear Aerodynamics Systems
Abstract
High performance aircraft have mission requirements for operating in high angle-of-attack and sideslip conditions and in various maneuvers of unsteady, large amplitudes governed by multiple-input, multiple-output nonlinear dynamics. The large amplitudes coupled with high degree nonlinear dynamics lead to requirements for nonlinear flying qualities. These qualities require analyses of nonlinear dynamic stability, nonlinear control, and nonlinear response behavior of such aircraft. Techniques are needed that 1) are computationally feasible, 2) retain the nonlinearities of the aircraft, and 3) provide physical and mathematical understanding of the important nonlinear flying qualities. This report documents the results of efforts to develop such techniques using the Volterra Series representation for nonlinear aircraft models of high angle-of-attack flight. Keywords: Nonlinear flying qualities, Nonlinear systems theory, Volterra equations, Nonlinear dynamics, High angle-of-attack.
