Abstract: An airfoil 10 to operate at Mach numbers between approximately .2 and 1.0 is designed to achieve high lift capability at low speed and also to minimize drag at high forward speeds. The leading edge region 30 of the airfoil has a relatively large radius of curvature 20 with a slightly drooped configuration to provide high lift at a low Mach number. The curvature of the upper surface 40 aft of the leading edge region and throughout the middle section of the airfoil 10 is relatively low to delay the onset of shock wave drag at moderate lift coefficients at transonic Mach numbers. The lower surface 50 of the airfoil 10 is shaped to provide a nearly uniform load distribution along the chord throughout the middle section at moderate lift coefficients to delay drag increases at transonic Mach numbers.

Abstract: An osteal prosthesis having an outer surface splined in a direction generally parallel to its mean axis is capable of being secured in the bone without cement, the bone tissue developing so as to at least partly occupy the interior or hollow between the splines. The cross-sectional profile of the splines is such that it imparts a bone tissue retaining capability, and the longitudinal interior surface or hollow of the splines, which are non-cylindrical, has a shape which tapers from the end of the prosthesis (lower end) which is the most deeply embedded in the bone to the other end (upper end), the prosthesis being thus capable of being extracted from the bone tissue by a tractive movement.
