A General Method for Calculating Three Dimensional Nonstationary Aeroelastic Response in Subsonic Flows.

Abstract

The study presents a generalized method which couples three dimensional, unsteady aerodynamic forces with elastic deformations and surface deflections for an arbitrarily configured vehicle imbedded in a subsonic flow field. Although the basic theories are well known, the composite formulation and technique of solving the resulting equations are new. Vortex lattice methods are extended to include unsteady motions and these methods are combined with current developments in structural dynamics to establish a unique approach for attacking problems involving dynamic aeroelastic phenomena.
