Abstract:
A method of attaching airfoils or hydrofoils, comprising:a. an airfoil or hydrofoil,b. an aircraft or hydrocraft structure,c. a means of attachment for upward deflection of said airfoil or hydrofoil relative to said aircraft or hydrocraft structure, defining an axis of rotation with upward deflection inclined upward toward the rear, whereby with upward deflection the trailing edge of said airfoil or hydrofoil will deflect more than the leading edge of said airfoil or hydrofoil, thus effectively reducing its angle of attack relative to disturbing airflow or waterflow, andd. a means of attachment for downward deflection of said airfoil or hydrofoil relative to said aircraft or hydrocraft structure, defining an axis of rotation with downward deflection inclined downward toward the rear, whereby with downward deflection the trailing edge of said airfoil or hydrofoil will deflect more than the leading edge of said airfoil or hydrofoil, thus effectively reducing its angle of attack relative to a disturbing airflow or waterflow.
