Embodiment Construction

[0069] See figure 1 and figure 2 , the embodiment of the present invention provides a transforming aircraft 100, which is used to carry certain accessories (such as cameras, robotic arms, etc.) . In this embodiment, the deformable air vehicle 100 may be a remote-control micro air vehicle.

[0070] The deformable aircraft 100 includes a casing 10 , a fuselage 20 and a frame 30 . The fuselage 20 is installed in the casing 10, the frame 30 is connected with the fuselage 20, the direction and angle of the frame 30 can be adjusted by controlling the fuselage 20, and the frame 30 protrudes from the casing 10 .

[0071] Please also see image 3 , Figure 5 and Image 6, the fuselage 20 includes a center frame 22 , a steering gear 24 and a transmission mechanism 26 . The center frame 22 is fixed in the casing 10 , and the center frame 22 is roughly a rectangular frame, which includes a top beam 221 , a chassis 222 , and a support frame 223 connected between the top beam 221 a...

Abstract

A morphing aircraft (100) includes a body (20) and a frame (30) connected to the body. The body (20) includes a transmission mechanism (26). The frame (30) includes a main supporting arm (31), a cross rod (33) and a spiral power mechanism (34). The main supporting arm (31) is connected to the transmission mechanism (26) of the body (20). The cross rod (33) is connected to the main supporting arm (31). The spiral power mechanism (34) is arranged on the cross rod (33). The transmission mechanism (26) includes a screw (261), at least two nuts (262, 263) screwed to the screw (261), and a nut adaption connector (265) that sleeves one of the nuts. The at least two nuts (262, 263) are connected mutually. The main supporting arm (31) is connected to the nut adaption connector (265). The dynamic stiffness of the whole aircraft is improved, the dynamic stiffness of the morphing aircraft during morphing and flying is achieved, the flying performance is improved, and also costs are reduced.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a deformable aircraft. Background technique [0002] In the field of aerial photography, micro-aircraft, especially quadrotor aircraft, are particularly suitable for performing tasks such as surveillance and reconnaissance in near-ground environments (such as indoors, urban areas and jungles, etc.), and have broad military and civilian prospects. In addition, novel appearance, simple structure, low cost, excellent performance and unique flight control method make it become a new international research hotspot. [0003] However, the fuselage of a general aircraft is a rigid structure, and the fuselage of a deformable aircraft has a lot of hinges, so the dynamic stiffness becomes worse. Therefore, how to improve the dynamic stiffness of the morphing aircraft has become an in-depth discussion in the industry. Contents of the invention [0004] In view of this, it is necessary to provide ...
