Abstract:
A configuration and system for rendering an aircraft spin resistant is disclosed. Resistance of the aircraft to spinning is accomplished by constraining a stall cell to a wing region adjacent to the fuselage and distant from the wing tip. Wing features that facilitate this constraint include but are not limited to one or more cuffs, stall strips, vortex generators, wing twists, wing sweeps and horizontal stabilizers. Alone or in combination, aircraft configuration features embodied by the present invention render the aircraft spin resistant by constraining the stall cell, which allows control surfaces of the aircraft to remain operational to control the aircraft.

Claim (Index 1):
A configuration for an amphibious aircraft so as to be spin resistant, said amphibious aircraft comprising a fuselage including sponsons coupled to a lower portion of the fuselage comprising a hull, a T-tail configuration, and a high wing having a leading edge coupled to an upper portion of the fuselage wherein the high wing includes a first region adjacent to the fuselage and a second region adjacent to a wing tip, the first region being contiguous with the second region, and wherein at high angles of attack a stall cell and associated separated airflow is constrained using a discontinuity in the leading edge of the wing to remain within the first region and flow below the T-tail so as to remain apart from flight controls located within the second region and flight controls associated with the T-tail.
