Abstract (en)
[origin: EP1306301A1] The camber on a propeller blade (12) acts in the opposite direction to the camber on the propeller. The propeller blade spreads from a conical transitional part (9) over a cylindrical hub part (10) to again a conical divergent end part (11). The outer end part of the propeller blade is formed by a cylindrical outer casing (13) equaling 10 to 50 percent of the length of the propeller blade's surface area.
