Abstract

1,001,011. Marine propellers. G. C. ENGSTRAND. Feb. 20, 1963 [June 11, 1962], No. 6872/63. Heading B7V. A marine screw propeller has its blades composed of substantially rhomboid cylindrical sections, the apparent pitch of the back and the face surfaces of the blades being constant for the entire blade length and the width of said cylindrical sections carying inversely with the cosine value of the inclination angles a with the disc area of the propeller.
