U.S. Patent Specifications

U.S. Patent Specifications The method of producing a hollow metal propeller blade from a tubular blank, which consists in providing the blank on opposite sides thereof with wallportions of varying thickness, flattening the outer portion of the tubular blank upon itself with the greater wallthickness at the folds, trimming the edges of the flattened portion of the blank to form facesections extending approximately from midlength of the blade to the tip along lines conformably to the leading and trailing edges of the blade, joining the sections along the leading and trailing edges, and expanding the joined sections to airfoil shape. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Aircraft Engineering and Aerospace Technology Emerald Publishing

Abstract

The method of producing a hollow metal propeller blade from a tubular blank, which consists in providing the blank on opposite sides thereof with wallportions of varying thickness, flattening the outer portion of the tubular blank upon itself with the greater wallthickness at the folds, trimming the edges of the flattened portion of the blank to form facesections extending approximately from midlength of the blade to the tip along lines conformably to the leading and trailing edges of the blade, joining the sections along the leading and trailing edges, and expanding the joined sections to airfoil shape.
