Abstract (en)
[origin: WO2019242799A1] Disclosed is a fan wheel which can be driven in only one rotational direction and in which the fan blades can be flipped about a reversal plane extending perpendicularly to the plane of revolution by rotating the fan wheel under the effect of inertia and by subjecting the fan blades to aerodynamic forces such that the direction of propulsion of the fan blades is inverted.
