Patent ID: 7487937

Claim:
An airfoil for a micro air vehicle, comprising: a leading edge section extending from a first tip to a second tip; an inboard section extending from the leading edge section toward a trailing edge of the airfoil; a first outboard section extending from the leading edge section toward the trailing edge of the airfoil and positioned on a first side of the inboard section; a second outboard section extending from the leading edge section toward the trailing edge of the airfoil and positioned on a second side of the inboard section that is opposite to the first side; at least one compliant region positioned between the first outboard section and the inboard section and extending from proximate the leading edge section to the trailing edge enabling the first outboard section to move relative to the inboard section about the leading edge section; and at least one compliant region positioned between the second outboard section and the inboard section and extending from proximate the leading edge section to the trailing edge enabling the second outboard section to move relative to the inboard section about the leading edge section; wherein the at least one compliant region positioned between the first outboard section and the inboard section comprises at least one slot extending from proximate the leading edge section to the trailing edge; and a seal positioned between the first outboard section and the inboard section enabling the first outboard section to move relative to the inboard section by bending about the leading edge section while substantially preventing equalization of pressure from a pressure side to a suction side of the airfoil through the at leapt one compliant region positioned between the first outboard section and the inboard section.
