Abstract

647,159. Aerofoils. GARBELL, M. A. Sept. 11, 1947, No. 24956. Convention date, Sept. 16, 1946. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 17, 1948.] [Class 4] An aerofoil comprises at least three spanwise control sections, the section with the smallest mean-line camber being at the root, while the camber and thickness ratio of the intermediate sections vary from those obtained by straight-line fairing between the root and tip, the camber of one or more of the intermediate sections exceeding that of the tip section. The purpose of the construction is to improve the stalling characteristics of the aerofoil, detailed particulars of the method employed to determine the location of the intermediate control sections (which is similar to that described in Specification 643,580) being given in the Specification. The curve 6, Fig. 4, represents the variation of lift coefficient throughout the span, the lines 17-18 and 17-19 being tangents to the curve at the root section and the section 7 at which the lift coefficient is a maximum. The optimum spanwise locations of the intermediate control sections are stated to be in the vicinity of the section 7 and that corresponding to the point 17 at which the tangents intersect.
