Abstract
The invention relates to a radial fanwheel, wherein the fan blades are connected to a hub by spokes. Each fan blade is connected by connecting elements to the adjacent fan blades in the vicinity of their ends. Specifically, the spokes and connecting elements, as well as the fan blades themselves, are elastically deformable by the loads which develop.
