Subsonic Steady and Oscillatory Aerodynamics for Multiple Interfering Wings and Bodies

A technique for predicting steady and oscillatory aerodynamic loadings on general configurations is presented for use in flutter, gust, and static aeroelastic analyses and estimation of static and dynamic stability derivatives. The procedures are based on the Doublet-Lattice Method and the method of images. Chordwise and spanwise load distributions on lifting surfaces and longitudinal load distributions on bodies are determined for configurations that consist of an assemblage of bodies (with variable circular or elliptic cross sections) and lifting surfaces (with arbitrary planform and dihedral, with or without control surfaces). Extensive comparisons are made with steady and oscillatory experimental lifting pressure data.
