| 简介 |
The drive rotor (10) has a rotor hub (12) and multiple rotor blades (14a, 14b). An air inlet (18) facing the blowing air is provided in the rotor hub. A spiral-shaped hub flow channel with a narrowing radius of curvature is attached to the air inlet. The hub flow channel passes into two similar rotor flow channels (22a, 22b) extending in rotor blades with radially increasing cross-section.Multiple guide vanes are arranged at the ends of the rotor flow channels for air deflection to an air outlet (28a, 28b) at the rotor blade rare edge in a circumferential direction. |
