Abstract

625,154. Propeller blades. DOCHERTY, J. W. Jan. 14, 1947, No. 1179. [Class 114] A propeller or fan blade has its main surface flat, but is curved and the face at its trailing edge G curved towards the back. To facilitate reversed running the leading edge F is bent similarly towards the face.
