Title:
VERTICAL TAKE-OFF AND LANDING AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2024/017525
Kind Code:
A3
Abstract:
The application provides a vertical take-off and landing, VTOL, aircraft, comprising a fuselage (3), the fuselage (3) comprising a nose (5), wherein the nose (5) contour is configured to be symmetrical about the symmetry plane and extends from the leading edge point (Pl) of the nose (5) to the middle fuselage (3). The nose (5) contour is divided into an upper surface (51) and a lower surface (53) by a horizontal plane passing through the leading edge point (Pl) and perpendicular to the plane of symmetry. The lower surface (53) bulges downward relative to the horizontal plane when the nose (5) contour expands from the leading edge point (Pl) to the middle fuselage (3), which is greater than the upper surface (51) bulges upward relative to the horizontal plane when the nose (5) contour expands from the leading edge point (Pl) to the middle fuselage (3). The VTOL aircraft (1) further comprises a pair of front wings (11) connected to the nose (5) and a pair of rear wings (13) connected to the tail (7). The pair of front wings (11) and the pair of rear wings (13) are arranged in a tandem wing layout. The arrangement position of the pair of front wings (11) on the nose (5) is adjacent to the horizontal plane in the vertical direction (15) perpendicular to the horizontal plane. The VTOL aircraft (1) of this application can meet the requirements of small size and high load by using the combination of the lower convex nose (5) contour and the tandem wing layout, and is especially suitable for urban air traffic scenes.
