Abstract: A wing assembly has a wing and one or more no-bias laminar flow oval diskettes that are fixed on a support structure along the C/L (center of lift) of an airfoil, of an aircraft wing. The benefit of an oval diskette with laminar flow is that it has no speed limitations and it allows an aircraft to clime at a speed that matches its Ground Effect Lift speed which is a 25% performance increase and a 40% reduction in vortex drag with a increase stability that eliminates inertia coupling of high-speed airfoils.
Abstract: A hull for a boat comprising a main hull bottom having a pair of hull bottom sides, each side having a first longitudinal inner edge and a second outer edge, with the hull bottom sides connected along the first inner edges and extending transversely upwardly and outwardly therefrom in a generally "V" shaped transverse cross section, each of the hull bottom sides having a main portion angled outwardly and upwardly from the first inner edge, and each of the hull bottom sides having a chine angled outwardly and downwardly from the main portion along a majority of the length of the second edge, a substantially vertical transom at the aft ends of the hull bottom sides, and a pair of raised after planing surfaces having forward ends at the transom and projecting aft of the transom and substantially parallel to and stepped slightly above the hull bottom sides immediately in front of the after planing surfaces, and the raised after planing surfaces also projecting aft generally parallel to and slightly above the chin
