Abstract

225,811. Soc. Anon. Nieuport-Astra. Dec. 4, 1923, [Convention date]. Screw propellers.-A screw propeller is manufactured from sheet iron plates bent into cylindrical form or of a form such as an ellipse or parabola generated by a straight line moving parallel to itself on a given directrix. A twobladed propeller is made in one piece, Fig. 1, with a main cylindrical portion and flat edges, the leading and trailing edges being cut so that at sections, as in Figs. 2 and 3, the angles of the sections are a, b respectively. The thickness of the sheet may be varied to taper off from root to tip.
