Document Type and Number:
Japanese Patent JP2023076891
Kind Code:
A
Abstract:
To reduce pressure resistance of a rotor head in a flight vehicle.SOLUTION: A flight vehicle is equipped with a rotor shaft protruding upward from a fuselage, a rotor head connected to the rotor shaft, above the fuselage, and a pair of plate units arranged above the fuselage and extended in a longitudinal direction at a right side and a left side of the rotor shaft. The pair of plate units include front ends, rear ends, inside surfaces pointing inward in a lateral direction, and outside surface pointing outward in the lateral direction, respectively. The front ends of the pair of plate units separate from each other in the lateral direction. The rear ends of the pair of plate units separate from each other in the lateral direction. The pair of plate units have shapes in which pressure at the outside surfaces becomes lower than pressure at the inside surfaces during a forward flight.SELECTED DRAWING: Figure 5
