Abstract:
To suppress pressure loss by suppressing separation of air from a stator blade in an electric fan and an electric vertical takeoff/landing aircraft.SOLUTION: An electric vertical takeoff/landing aircraft includes: a boss part; a periphery arranged around the boss part; a rotator blade arranged between the boss part and the periphery and supported freely rotatable around the boss part; a drive part provided on the periphery to rotate the rotator blade; and a stator blade arranged closer to a downstream side than the rotator blade in a flow direction of fluid between the boss part and the periphery. The stator blade has a plurality of state blade bodies arranged at intervals in a circumferential direction. In a stator blade body located in an area with an obstacle arranged outside in a radial direction among the plurality of stator blade bodies, a guide part for guiding the fluid to an inner diameter side is provided at an upstream front edge part in the flow direction of the fluid or an edge part on a negative pressure surface side on the inner diameter side.SELECTED DRAWING: Figure 1
