Abstract : The acceleration potential method is applied to the solution of linear problems arising in incompressible flow past a wing positioned above the interface between fluids of different densities. Some general results obtained for problems involving the motion of lifting wings at high Froude numbers are discussed. Simple formulas are derived for a wing in two-dimensional flow and for a high-aspect-ratio, finite-span wing. An exact formulation of the problem is obtained for small density ratios. (Author)
