Abstract

208,462. Grilli, A. March 26, 1923. Screw propellers. -Screw propeller blades 12 of the kind which extend 180‹ round the hub 10 are formed with the radial width gradually increasing from the leading edge 13 to a position near the after edge from which position it decreases up to the after edge 14. The pitch is constant at all diameters.
