AERODYNAMIC CHARACTERISTICS OF RING WINGS, A BIBLIOGRAPHY

Abstract : The cited references pertain primarily to the following aerodynamic information on ring wings, also known as annular wings or circular wings: Calculation of circumferential velocity and pressure distribution, studies on flow separation phenomena at the wing leading and trailing edges, measurement of lift, drag and pitching moment, application of linearized theory to subsonic and supersonic gas flow, theory and measurement of vortex drag, measurement of three-dimensional turbulent boundary layer, determination of flutter using linearized equations, theory of stationary, inviscid, incompressible flow around the wing, studies on drag reduction, studies on interference effects of an axisymmetric fuselage or a structure on wing pressure distributions, wind tunnel tests of wings with and without a fuselage, and determination of optimum shape.
