Abstract

377,804. Screw propellers. POOT, P., 45, Rue des Tilleuls, Saventhem, Belgium. July 10, 1931, No. 19927. Convention date, Aug. 18, 1930. [Class 114.] Screw propellers for aircraft have their trailing- edges formed with corrugations 3 which die out in the neighbourhood of the straight leading edge 4. The troughs of the corrugations in the neighbourhood of the hub 7 are struck from the centre 9 whilst those at the ends lie on arcs struck about a centre 10 on the hub which is an extension of the leading edge of the blade.
