Patent ID: 7967252

Claim:
An airfoil for use on a high speed, jet powered airborne mobile platform, and secured to an exterior surface of said mobile platform at a location so as to be disposed within a boundary layer during flight of the mobile platform, the airfoil comprising: a chord length designated by X; a chord thickness at a local center line representing a thickness designated by Z; wherein one-half of a thickness (Z) of said chord forms a ratio (Z/X) approximately within a range of about 11-13%; and said airfoil producing a peak Mach number for airflow over a longitudinal centerline of said airfoil that is no greater than about Mach 1.2 when said mobile platform is moving at a speed of about Mach 0.85 with a relative constant Mach number flow over a region defined as at least an approximate 20% length of maximum thickness of said airfoil; said airfoil further having a drag coefficient that is relatively constant and less than a value of about 0.10 up to an airspeed of about Mach 0.9; said airfoil further having a pressure distribution (Cp) that is positive at a trailing edge; and said airfoil further having a frontal portion forming an angle at a half height point thereof of between about 20 degrees to about 32 degrees relative to the exterior surface of the mobile platform.
