A linearized theory is developed to treat small-amplitude unsteady motions of a wing in curved flight at variable local forward speeds in an inviscid incompressible fluid. The wing geometry, motions, and flight path are specified and the problem is to obtain the time-dependent force, moment, power required to sustain the motion, pressure and velocity fields, and energy loss due to the shedding of vorticity. The theory is expected to provide useful estimates provided the wing does not cross its own wake. The effect of path curvature is a particular interest in this investigation. To contrast this effect, the results can be readily compared with those for a wing in straight-line flight. (Author)
