Title:
MORPHING AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2021/109312
Kind Code:
A1
Abstract:
A morphing aircraft, comprising a fuselage (1), an inner variable wing segment (2), an outer variable wing segment (3), a high-speed wing segment (4), and a morphing mechanism (6). The inner variable wing segment (2) is rotatably connected to the fuselage (1). All the wing segments are rotatably connected. The inner variable wing segment (2) and the outer variable wing segment (3) form a variable wing segment, and a morphing operation is achieved by means of the morphing mechanism (6). The inner variable wing segment (2), the outer variable wing segment (3) and the high-speed wing segment (4) are all provided with control surfaces. The morphing aircraft uses a high aspect ratio at low speed to realize high-efficiency flight and shorten the ground-run distance, and is changed into an aircraft having a low aspect ratio at high speed to reduce resistance and improve the maneuverability. In conclusion, the goals of high speed and high maneuverability are achieved, and the flight speed and maneuverability of the aircraft are improved.
