A lightweight, man carrying aircraft including a skeletal fuselage assembly in combination with a primary arc-shaped lifting airfoil having variable camber, incidence angle, and pitching moment and a secondary stabilizing airfoil of a tubular, ring-like configuration. The arc-shaped primary airfoil is superior to traditional low speed airfoil forms due to its high aerodynamic efficiency, inherent design simplicity and strength. The ring-tail assembly, offering marginal aerodynamic lift, contributes significantly to the in-flight stability and safety of t...
An aircraft comprising fuselage means forming the support structure of an aircraft, airfoil means carried by said fuselage means and adapted to provide aerodynamic lift during flight of the aircraft, said airfoil means forming a continuous wing surface of an arcuate configuration during flight, said continuous wing surface being formed of a flexible, fabric-like, material assuming said configuration during flight, said airfoil means extending upwardly from said fuselage means and having respective ends coupled thereto, said wing surface forming an increa...
