Flight conditions for rotating cylindrical wing

Analysis of conventional wing dynamics exhibits limits imposed by physical laws which cannot be fully compensated by wing profile optimization nor by artificial flow lines modification. A different alternative is proposed by modifying drastically wing shape into a tubular one. It is shown here that such wings take advantage of their geometry allowing an enhanced new lifting effect produced by the apparent velocity due to the combination of their velocity with a rotation around their symmetry axis. At the same time this rotation generates a gyroscopic stabilization of the wing around its symmetry axis during its trajectory which can be more easily controlled for a large range value of angle of attack. In particular there results a much larger value of stall angle. These theoretical results have been verified by preliminary observations on a small size 3D printed model.
