Problems solved by technology

[0002] At present, in the design of the connecting structure of the wing and fuselage of the aircraft, the wing and the fuselage are separated structures, which occupy a particularly large space in packaging, transportation, and storage or are not convenient for the aircraft to be used in transition.
Especially for small aircraft, it is usually transported by car, and the disengagement of the wing and the fuselage usually leads to inaccurate positioning, difficult reinstallation, many operation and maintenance personnel, and long time-consuming difficulties.

Abstract

The invention relates to a rotatable and telescopic plane wing connection structure and belongs to the field of structural design of planes. A plane wing can be raised to a certain height convenientlyand can rotate by a certain angle in a certain direction after the structure is connected with a plane body and the plane wing. When a plane is transported or stored, the plane wing can be raised androtated quickly through the structure until the plane wing is parallel with the plane body, and the packaging, transportation and storage space is reduced; when the plane is used, the plane wing canbe rotated to a proper position quickly through the structure, and the installation and debugging time of the plane is saved. Meanwhile, the structure has the functions of limiting to raising height and angle rotation, can prevent the plane wing from collision caused by maloperation in the raising or rotation process, can facilitate quick positioning and is convenient to operate.

Description

technical field [0001] The application relates to a retractable composite structure suitable for small aircraft, which has the function of connecting wings and fuselage without detachment and being rotatable, and belongs to the field of aircraft structure design. Background technique [0002] At present, in the design of the connection structure of the aircraft wing and fuselage, the wings and the fuselage are separated structures, which occupy a large space in packaging, transportation, and storage or are not convenient for the aircraft to be used in transition. Especially for small aircraft, it is usually transported and transferred by car, and the disengagement of the wings and the fuselage usually leads to inaccurate positioning, difficult reinstallation, many operation and maintenance personnel, and long time-consuming difficulties. Contents of the invention [0003] The purpose of the present invention is to provide a rotatable telescopic structure suitable for small...
