Aircraft
An aircraft includes a fuselage body extending in a front-rear direction; a tail wing at a rear portion of the fuselage body in the front-rear direction; a main wing in front of the tail wing in the front-rear direction on the fuselage body; and a fan device on an outer surface of the fuselage body. The fan device includes a rotor shaft outside the outer surface of the fuselage body, a rotor blade on an outer side of the rotor shaft in a rotor radial direction with the rotor shaft as a center, a housing fixed to the fuselage body, extending in the front-rear direction, including respective openings at a front and a rear in the front-rear direction, and provided to cover the rotor shaft and the rotor blade, a stator blade.
1. An aircraft comprising:
a fuselage body extending in a front-rear direction;
a tail wing provided at a rear portion of the fuselage body in the front-rear direction;
a main wing provided in front of the tail wing in the front-rear direction on the fuselage body; and
fan devices provided on an outer surface of the fuselage body, wherein
each of the fan devices includes:
a rotor shaft disposed outside the outer surface of the fuselage body in a fuselage radial direction and provided to be rotatable around a central axis extending in the front-rear direction,
a rotor blade provided on an outer side of the rotor shaft in a rotor radial direction with the rotor shaft as a center,
a housing fixed to the fuselage body, extending in the front-rear direction, including respective openings at a front and a rear in the front-rear direction, and provided to cover the rotor shaft and the rotor blade,
a stator blade including a stator blade tip portion and extending inward from an inner peripheral surface of the housing in the rotor radial direction to the stator blade tip portion of the stator blade, and
stator blade fluid suction portions that suction a fluid on a stator blade tip portion side of the stator blade on an inner side of the rotor radial direction,
the stator blade fluid suction portions are disposed at intervals in a rotor circumferential direction around the rotor shaft, and
each of the stator blade fluid suction portions includes:
a first opening portion that opens at the stator blade tip portion;
a second opening portion that opens behind the fan devices in the front-rear direction; and
a first flow path portion through which the first opening portion and the second opening portion communicate.
2. The aircraft according to claim 1 , wherein the fan devices are provided at intervals in a fuselage circumferential direction along the outer surface of the fuselage body on an outer side of the fuselage body in the fuselage radial direction.
3. The aircraft according to claim 1 , wherein an opening area of the first opening portion of the stator blade fluid suction portions disposed on a side closer to the fuselage body with respect to the rotor shaft is larger than an opening area of the first opening portion of the stator blade fluid suction portions disposed on a side farther from the fuselage body with respect to the rotor shaft.
4. The aircraft according to claim 1 , further comprising:
an opening-closing valve that intermittently interrupts suction of the fluid in the stator blade fluid suction portions.
5. The aircraft according to claim 1 , further comprising:
rotor blade fluid suction portions that suction the fluid inside the housing on an outer side of the rotor blade in the rotor radial direction.
6. The aircraft according to claim 5 , wherein
the rotor blade includes a rotor blade tip portion, and
each of the rotor blade fluid suction portions includes:
a third opening portion that opens to face the rotor blade tip portion in the rotor radial direction;
a fourth opening portion that opens behind the third opening portion in the front-rear direction; and
a second flow path portion through which the third opening portion and the fourth opening portion communicate.
