Aerodynamic Interference between Oscillating Lifting Surfaces and Fuselage Part 1: Oscillating Lifting Surfaces

This is the first of a series of articles that deal with the calculation of the aerodynamic unsteady forces on lifting surfaces (wing, empennages) in the presence of the fuselage. The aim of this work is multiple: the calculation of flutter, gust effect, aerodynamic response to manoeuvres, flapping wings. The first paper presents the lifting surface model, the integral equation of the oscillating surface, its numerical solution and some numerical results. The next papers will deal with the aerodynamic modeling of the fuselage in the presence of harmonic disturbances as those produced by the fuselage itself or an oscillating wing. Finally, we present the last step to achieve the interference: modeling of the fuselage lift due to the wing or empennages.
