Embodiment Construction

[0014] This embodiment is a telescopic deformable wing transmission mechanism, including a reduction motor 1, a winch 2, a steel cable 3, a main wing wing tip pulley 4, and a wing telescopic section 5. The geared motor and the winch are fixedly connected and installed on the wing side against the fuselage; the main wing pulley is installed at the end of the main beam under the wing surface of the main wing tip; the relative distance between the front and rear of the winch and the pulley is zero, and they are on the same plane; steel The cable is divided into two parts: contraction steel cable and extension cable: the contraction steel wire is directly connected to the winch and the root of the telescopic wing; the extension cable starts from the winch, and the lower surface of the extended wing skin turns 180° after passing through the wing pulley. The upper surface of the extended and retracted wing is fixedly connected with the root of the retractable wing. As a result, the s...

Abstract

The invention discloses a transmission mechanism of telescopic morphing wing, which comprises a speed reducing motor, a steel cable, a winch and a pulley and is characterized in that: the speed reducing motor drives the winch to unwind and wind the steel cable wound on the winch; a telescopic section of the wing, the steel cable, the winch and the pulley are embedded in a main wing; the pulley is positioned at the tail end of a girder under a wing face skin on the wing tip of the main wing; and steel cable controls the telescopic change of the telescopic section of the wing in real time through the pulley. The transmission mechanism of the telescopic morphing wing has the advantages of simple structure, light weight, safety, reliability and the like, can relatively better meet the requirements on the structure of an aerocraft, takes efficiency and weight into account and fulfils the aim of the telescopic change of the wing.

Description

Technical field [0001] The invention relates to a wing telescopic mechanism for a wing telescopic deformable wing aircraft (transformation aircraft), in particular to a telescopic mechanism based on a steel cable pulley that can control the amount of expansion and contraction rate. Background technique [0002] Deformed wing aircraft have always been a hot topic in the aviation industry. Successfully produced deformed wings abroad mainly use mechanical mechanisms to change the wing span, chord length, wing area, wing sweep angle, etc., through design Mechanical transmission mechanism, making physical models to find the wing deformation methods that can be adopted at this stage. In summary, today's wing deformation technology can be divided into the following two categories: [0003] (1) A deformed wing technology mainly refers to the technology of changing the aerodynamic shape in order to obtain the required flight performance. For example, F-14 fighter and Tu-160 bomber's varia...
