Abstract
A disc-type vertical take-off and landing aircraft includes the following. A skirt widens toward the bottom. A disc-shaped rotor is positioned on a lower side of the skirt and rotates with relation to the skirt. A plurality of blades are provided standing on an upper surface of the rotor and are positioned radially from a center of the rotor. A cutout is formed in each of the plurality of blades. When the rotor rotates, centrifugal force causes an airflow along the blade rotating with the rotor, the airflow swirls in a spiral by a flow of air flowing over the cutout of the blade in a direction substantially orthogonal to the blade, the airflow flows in a radial direction of the rotor along the blade while swirling in the spiral, and the airflow ejected downward by the skirt causes ascending.

A disc-type vertical take-off and landing aircraft comprising:
- a skirt that widens toward a bottom;
- a disc-shaped rotor that is positioned on a lower side of the skirt and that rotates with relation to the skirt;
- a plurality of blades that are provided standing on an upper surface of the disc-shaped rotor and that are positioned radially from a center of the disc-shaped rotor;
- and
- a plate-shaped member that is provided with an opening at a central portion and that links upper portions of the plurality of blades,
- wherein a cutout is formed in each of the plurality of blades,
- wherein air that flows from the opening passes a space that is formed surrounded by the skirt, the disc-shaped rotor and the plate-shaped member, and a portion divided by each of the plurality of blades, and
- wherein when the disc-shaped rotor rotates, centrifugal force causes an airflow along the blade rotating with the disc-shaped rotor, the airflow swirls in a spiral by a flow of air flowing over the cutout of the blade in a direction substantially orthogonal to the blade, the airflow flows in a radial direction of the disc-shaped rotor along the blade while swirling in the spiral, and the airflow ejected downward by the skirt causes the disc-type vertical take-off and landing aircraft to ascend.
