Abstract

227,064. Salter, M. Aug. 14, 1924. Screw propellers.-The developed area of screw propeller blades G is obtained from the geometrical construction shown in Fig. 1, the blades being given a suitable twist, the angle at the root being 45‹. For use on fast aeroplanes two blades only would be used, but four or six blades mav be employed. For use on ships, one-sixth of the root portion only is used.
