Abstract:

This report describes the results of a study of the feasibility of extending the time domain formulation of the linearized aerodynamics of flexible bodies that had been developed earlier for planar wings to the general case of arbitrary, complete aircraft, configurations. The end products of that study are a formulation of the problem, an exact solution applicable to any geometry, a sample calculation for a simple nonplanar configuration, and some suggestions on how to proceed. The formulation is based on distributions of elementary sources and doublets over the mean solid surface. The problem is first formulated for arbitrary motion, and then specialized to the case of uniform translation.
