Abstract:
PCT No. PCT/EP91/00612 Sec. 371 Date Sep. 23, 1992 Sec. 102(e) Date Sep. 23, 1992 PCT Filed Apr. 1, 1991 PCT Pub. No. WO91/15399 PCT Pub. Date Oct. 17, 1991.Propeller with twistable blades comprising a spar with ribs which can be rotated in opposite directions about the axis of the spar by an adjusting device. A coupling device in the propeller ensures that when two ribs are rotated in opposite directions by the adjusting device, the other ribs are adjusted accordingly. The coupling device consists of a rod substantially parallel to the spar and designed to be relatively bendable in the plane through the spar and the rod, and relatively resistant to bending in the plane perpendicular thereto. The rod couples at least three ribs together in such a way that it distorts when two ribs are rotated in opposite directions along a helix about the spar, causing subsequent ribs to move with it on this helix.
