Keywords: numerical simulation, unsteady aerodynamic response, complete aircraft

A linearized potential-flow method and an Euler method are applied to the numerical simulation of the unsteady flow aimed at the prediction of longitudinal dynamic parameters for a complete aircraft configuration. Described are the indicial plunge response for a configuration that includes the wing, tail surfaces, the fuselage, the aftmounted engine nacelle, the engine pylon and the engine exhaust. The results reveal the importance of considering a detailed model of the complete configuration for the accurate determination of the dynamic response.
