AIRCRAFT
Document Type and Number:
Japanese Patent JP2023092936
Kind Code:
A
Abstract:
To reduce resistance experienced by a boom during cruising.SOLUTION: An aircraft includes: a fuselage; a front wing and a rear wing provided to extend laterally from the fuselage for generating lift during cruising; a boom 18 supported by the front wing and the rear wing while being spaced apart from the fuselage; and at least one VTOL rotor supported on the boom and having one or more blades for generating thrust in a vertical direction during take-off and landing. In a top view, the boom has a shape in which a barrel part extends in a front-rear direction while being curved in a direction away from the fuselage with respect to a front end and a rear end. In addition, in a front view, the boom has a cross-sectional shape which has an upper side formed in a round curved shape, which is tapered from the upper side toward a lower side, and which has the lower side formed in a substantially flat shape. Since, in the front view, the boom has the cross-sectional shape which has the upper side formed in the round curved shape, which is tapered from the upper side toward the lower side, and which has the lower side formed in the substantially flat shape, turbulence in airflow can be eliminated or suppressed, so that air resistance experienced by the boom during cruising is reduced, thereby making it possible to cruise with small resistance.SELECTED DRAWING: Figure 6A
