Abstract

1,190,271. Helicopter rotors; air cushion vehicles; screw propellers. D. B. SUGDEN. 27 April, 1967, No. 19359/67. Headings B7K, B7V and B7W. [Also in Division F1] A propeller or helicopter rotor comprises a continuous sinuous working surface disposed about the axis of rotation and having a changing axial section shape and ridge and valley regions, each axial section of the working surface curving smoothly throughout its full extent in the direction of general flow and generally conforming to a sine-like curve which undulates smoothly in the direction of general flow, each successive axial section occupying a slightly advanced position on its sine-like curve from the position of the preceding axial section on its sine-like curve, and the change in curvature of the working surface along all paths of actual flow over the working surface occurring at a rate resulting in a smoothly undulating flow pattern being imparted to the fluid and the direction of undulation smoothly reversing through the ridge and valley regions. Fig. 2 shows a marine or aerial propeller or a helicopter rotor comprising a single annular blade 10 attached to a hub 12 by two arms 14 which, as shown, may curve rearwardly slightly from their inner to their outer ends. In cross-sections taken at right angles to the axis X of rotation, the blade 10 comprises several complete waves, e.g. two as shown, which may be sine waves generated from a circular axis Y of generation. The cross-sections change progressively in angular disposition from the leading edge of the blade to the trailing edge along a helical path but remain of substantially the same configuration. Both the inner and outer surfaces of the blade 10 form working surfaces. An under water vessel V, Fig. 16, comprises a rotating propeller R3<SP>1</SP> interposed between non-rotating sections 18, 20. The rotor is in this ease of solid form with an outer working surface formed as described above. Fig. 21 shows an air cushion vehicle comprising a fan rotor R6 which draws in air at 42 and discharges it downwardly within an annular wall 44. The rotor is of sinelike profile in axial section as shown to form a working channel which spirals outwardly from the centre to the outer edge of the rotor.
