Abstract
An aircraft that performs vertical take-off and landing includes: a fuselage; at least one pair of fixed wings; a rotor blade; a rotational drive unit that rotationally drives the rotor blade by electric power; and a support that has an inner space that accommodates at least a part of the rotational drive unit, and supports the rotor blade, wherein the support has a first opening forming portion that has a first opening communicating the inner space and the outside of the support at a position different from a position downstream of an airflow blown by rotation of the rotor blade, and a second opening forming portion that has a second opening communicating the inner space and the outside of the support at a position downstream of the airflow blown by rotation of the rotor blade.
Claims20
An aircraft that performs vertical take-off and landing, the aircraft comprising:
- a fuselage;
- at least one pair of fixed wings that extends in a left-right direction from the fuselage;
- a rotor blade configured to generate thrust to propel the aircraft vertically upward by being rotationally driven;
- a rotational drive unit configured to rotationally drive the rotor blade by electric power;
- and
- a support that extends in a front-back direction of the aircraft, has an inner space that accommodates at least a part of the rotational drive unit, and supports the rotor blade, wherein
- the rotor blade is rotatably supported by the support vertically above the support,
- the support has a first opening forming portion that has a first opening communicating the inner space and an outside of the support at a position different from a position downstream of an airflow blown by rotation of the rotor blade, and a second opening forming portion that has a second opening communicating the inner space and the outside of the support at a position downstream of the airflow blown by rotation of the rotor blade in such a manner that air in the inner space flows out to the outside of the support due to decrease in pressure in the vicinity of the second opening by the airflow blown by rotation of the rotor blade,
- the support is located vertically below the fixed wing, and extends from a position in front of the fixed wing to a position behind the fixed wing, and
- the first opening forming portion is located at an end face of the support in vertically upward direction.
A rotor blade module fixed to a fixed wing extending in a left-right direction from a fuselage of an aircraft, the rotor blade module comprising:
- a rotor blade configured to generate thrust to propel the aircraft vertically upward by being rotationally driven;
- a rotational drive unit configured to rotationally drive the rotor blade by electric power;
- and
- a support that extends in a front-back direction of the aircraft, has an inner space that accommodates at least a part of the rotational drive unit, and supports the rotor blade, wherein
- the rotor blade is rotatably supported by the support vertically above the support,
- the support has a first opening forming portion that has a first opening communicating the inner space and an outside of the support at a position different from a position downstream of an airflow blown by rotation of the rotor blade, and a second opening forming portion that has a second opening communicating the inner space and the outside of the support at a position downstream of the airflow blown by rotation of the rotor blade in such a manner that air in the inner space flows out to the outside of the support due to decrease in pressure in the vicinity of the second opening by the airflow blown by rotation of the rotor blade,
- the support is located vertically below the fixed wing, and extends from a position in front of the fixed wing to a position behind the fixed wing, and
- the first opening forming portion is located at an end face of the support in vertically upward direction.
