A system for enhanced lateral stability of an amphibious aircraft includes a buoyancy system laterally displaced from opposite sides of the fuselage of the aircraft and wingtip system having a hydrodynamic planing surface associated with each wingtip. The hydrodynamic planing surface on each wingtip prevents the submersion of an associated buoyancy structure. By supplementing the lateral stability of the buoyancy structures using hydrodynamic planing surfaces, the combined lateral width of the fuselage and buoyancy structures can be reduced without detri...

1. A system for enhanced lateral stability of an amphibious aircraft, the amphibious aircraft having a polyhedral wing and a fuselage, the system comprising: a buoyancy system laterally displaced from the fuselage wherein the buoyancy system includes a hydrodynamic step; anda wingtip system associated with each wingtip of the polyhedral wing of the amphibious aircraft wherein each wingtip system includes an anhedral wingtip with a positive angle of incidence and at least one hydrodynamic planing surface. 2. The system of claim 1 wherein the at least one hydrodynamic planing surface associated with each anhedral wingtip possesses a tip dihedral orientation such that upon rolling of the amphibious aircraft sufficient for the anhedral wingtip to make contact with a water surface the at least one hydrodynamic planing surface is substantially parallel with the water surface. 3. The system of claim 2 wherein initial contact of the wingtip system with the water surface is a trailing edge of the at least one hydrodynamic planing surface. 4. The system of claim 1 wherein the buoyancy system provides static waterborne lateral stability to the amphibious aircraft. 5. The system of claim 1 wherein the at least one hydrodynamic planing surface includes a sharp inboard trailing edge and a sharp outboard trailing edge. 6. The system of claim 1 wherein the hydrodynamic planing surface is operable to produce a dynamically increasing righting force in opposition to a submersion force associated with the buoyancy system when at least a portion of the buoyancy system is submerged. 7. The system of claim 1 wherein responsive to the hydrodynamic planing surface of at least one wingtip making water contact while the amphibious aircraft is in motion, the planing surface of the at least one wingtip produces a dynamically increasing righting force substantially perpendicular to the planing surface of sufficient strength to prevent submersion of any portion of the buoyancy system. 8. The system of claim 1 wherein the hydrodynamic planing surface of the wingtip prevents submersion of at least a portion of the buoyancy system when the amphibious aircraft rolls about an axis aligned with the fuselage. 9. The system of claim 1 wherein responsive to the hydrodynamic planing surface of at least one wingtip making water contact while the amphibious aircraft is in motion, the planing surface of the at least one wingtip produces a substantially coordinated waterborne turn. 10. The system of claim 1 wherein the amphibious aircraft is configurable to be transported on a trailer such that a combined width of the amphibious aircraft and the trailer is less than or equal to 9 feet without modifying the buoyancy system or the wingtip system. 11. The system of claim 1 wherein the polyhedral wing of the amphibious aircraft is folded without any modification to the wingtip system or removal from the amphibious aircraft such that a total width of the amphibious aircraft without modifying the buoyancy system or wingtip system is less than or equal to 7 feet, 6 inches. 12. The system of claim 1 wherein the polyhedral wing of the amphibious aircraft is folded without any modification to the wingtip system or removal from the amphibious aircraft to be transported on a trailer, the trailer having a width less than or equal to a maximum federal allowable legal width for transport trailers within the United States of America. 13. The system of claim 1 wherein a lateral width of the amphibious aircraft when the polyhedral wing is folded while remaining attached to the amphibious aircraft to be transported on a trailer is less than or equal to a maximum federal allowable legal width for transport trailers within the United States of America. 14. A lateral stability system for an amphibious aircraft, the amphibious aircraft including a polyhedral wing and a fuselage, the system comprising: a buoyancy structure associated with the fuselage of the amphibious aircraft wherein the buoyancy system includes a hydrodynamic step; anda hydrodynamic planing surface possessing a positive angle of incidence located at each of opposite ends of the polyhedral wing. 15. The lateral stability system of claim 14 where the hydrodynamic planing surface is associated with an anhedral wingtip. 16. The lateral stability system of claim 14 wherein the hydrodynamic planing surface associated with the anhedral wingtip possesses a tip dihedral orientation such that upon interaction with a water surface the hydrodynamic planing surface is substantially parallel with the water surface. 17. The lateral stability system of claim 14 wherein responsive to the hydrodynamic planing surface making contact with a surface of water during motion of the amphibious aircraft, the hydrodynamic planing surface produces a righting force that increases dynamically with respect to displacement and speed substantially perpendicular to the surface of water. 18. The lateral stability system of claim 17 wherein the righting force prevents submersion of the buoyancy structure. 19. The lateral stability system of claim 14 wherein a lateral width of the amphibious aircraft, the buoyancy structure and the hydrodynamic planing surface located at each ends of the wing, can be configured by folding the polyhedral wing without modification to the hydrodynamic planing surface or removal from the amphibious aircraft to be less than or equal to a maximum federal allowable legal width for transport trailers within the United States of America.
