Abstract

640,393. Screw propellers. ROLLS-ROYCE, Ltd. Oct. 10, 1947, No. 27312. [Class 114] A spinner has concentric structures 13, 14, between which is an air passage, the crosssection of which is adjusted so that in the way of the fairings 17 of the propeller blades, the effective cross-section is maintained constant. The fairing is formed so that its angle of incident to longitudinal flow is progressively increased at increasing radii.
