Document Type and Number:
Japanese Patent JP2023017518
Kind Code:
A
Abstract:
To expand an employment range of fan devices and improve the propulsion efficiency of an aircraft, by suppressing separation of an air flow inside a housing.SOLUTION: An aircraft comprises an airframe body, a tail unit, main wings, and fan devices. The fan devices mounted to an exterior surface of the airframe body comprise: a rotor shaft, moving blades, a housing, stator blades, and stator blade fluid suction parts. The rotor shaft is arranged outside of the exterior surface of the airframe body in an airframe radial direction. The moving blades are provided outside in a rotor radial direction with the rotor shaft as a center, relative to the rotor shaft. The housing extends in a forward and rearward direction, and has a respective opening in the front and in the rear in the forward and rearward direction. The housing is provided so as to cover the rotor shaft and the moving blades. The stator blades extend inward in the rotor radial direction from an inner peripheral surface of the housing. The stator blade fluid suction parts suction fluid from gaps between stator blade tip portions on the inside of the stator blades in the rotor radial direction and the rotor shaft.SELECTED DRAWING: Figure 2
