EDGE DRIVE TYPE FAN, DOUBLE-STATE SWITCHING MECHANISM AND WING, AND VERTICAL TAKEOFF AND LANDING AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2020/244625
Kind Code:

Abstract:
An edge drive type fan, a double-state switching mechanism and wing, and a vertical takeoff and landing aircraft, relating to the field of aviation. The edge drive type fan comprises a housing (10); the interior of the housing is provided with a driving component (20) and multiple blades (30); the driving component is provided in a surrounding mode; the driving component is connected to the edges of the multiple blades and used for driving the multiple blades to move along the surrounding direction of the driving component; the interior of the housing is further provided with a driving structure (40) used for driving the driving component to move along the surrounding direction thereof. The edge drive type fan reduces the total thickness of the fan, reduces the total volume of the fan, increase the possibility that the fan is integrally mounted in the wing, and is adapted to the fundamental requirements of an in-wing lift fan; moreover, the edge drive type fan provides a novel fan blade motion mode, i.e., a linear displacement mode, thereby overcoming an inherent defect that in the circular motion of a traditional fan blade, at the same rotation speed, the closer a point on the blade is to the center of the circle, the slower the rotation speed is, and greatly increasing a lift force generated by the fan and improving the propelling efficiency of the fan.
