Abstract

669,112. Screw propellers. ROTOL, Ltd. June 16. 1950 [June 20. 1949], No. 16374/49 Class 114. The blade has a leading edge portion formed of a sheet metal member 13, spaced from the body portion 6 at the front end, and reinforced with a strip 10 shaped to give a sharp leading edge 11. The leading edge space may house a heating unit comprising an electric wire 33 protected by mica plates. In a modification the metal sheet 13 is bent to give a sharp leading edge and is fitted with reinforcement on the inside. Specification 639,082, [Group XXX], is referred to.
