Abstract (en)
[origin: WO9832652A1] Propulsion device comprising a number of profiled propeller blades (6) being circumferentially distributed and being mounted between two discs (4) rotatably arranged around a horizontal shaft (7) in such a way that the axes of the blades are almost square to the planes of the discs (4). Means (9 - 14) for rotating the blades (6) around their shafts (5) in relation to said discs have been provided. To that end, the shaft (5) of each blade (6) is provided with a chain wheel (9), which, by means of a chain (10) is connected to an adjusting chain wheel (11) being rotatably mounted on the portion of the drive shaft (7) extending beyond the discs (4) connected to each other. The adjusting chain wheel (11) is connected to means (12 - 14) for rotating it forward and backward across a limited anglee limité.
