Title:
円盤型垂直離着陸機
Document Type and Number:
Japanese Patent JP7284685
Kind Code:
B2
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.
