Embodiment Construction

[0035] The retractable shape-conforming wing provided by the present invention is described below.

[0036] figure 1 For the structural representation of the retractable conformal wing provided by the present invention, refer to figure 1 , a retractable wing, comprising: a fixed inner wing section 1, a telescopic mechanism 2, a wingtip shape-retaining device 3, a leading edge shape-retaining device 4, a trailing edge shape-retaining device 5, at least one shape-retaining stringer 6 and an elastic covering skin7.

[0037] The application mode of the present invention is specifically that when the outer wing section needs to extend out of the inner wing section, the telescopic mechanism 2 drives the wingtip shape-retaining device 3 to move away from the inner wing section 1, and the wingtip shape-keeping device 3 is in the process of horizontal movement , drive the leading edge shape-retaining device 4, trailing edge shape-retaining device 5 and each shape-retaining stringer 6...

Abstract

The invention provides a telescopic conformal wing. The telescopic conformal wing comprises a fixed inner wing section (1), a telescopic mechanism (2), a wingtip conformal device (3), a leading edge conformal device (4), a trailing edge conformal device (5), at least one conformal stringer (6), an elastic skin (7) and a shape retaining device. According to the telescopic conformal wing, the telescopic mechanism, the conformal assembly and the elastic skin are designed, free contraction of the outer wing section is achieved, and the telescopic conformal wing has the advantages of being light instructural weight, controllable in telescopic length, capable of well keeping the shape of the wing and the like. According to the invention, the problems of large structural weight, unsmooth transition between two sections, poor wing surface shape maintenance and low aerodynamic efficiency of the traditional mode that the outer wing section is integrally retracted into the inner wing section aresolved. The method can be applied to aircrafts or flight verification platforms with wings needing telescoping.

Description

technical field [0001] The invention relates to the field of aircraft wing design, in particular to a retractable shape-conserving wing. Background technique [0002] Most of the existing retractable wing structures are the outer wing section retracted into the inner wing section as a whole, which has the problems of heavy structural weight, rough transition between the two sections, poor shape maintenance of the airfoil surface, and low aerodynamic efficiency. Contents of the invention [0003] The invention provides a retractable shape-conforming wing, which can alleviate the problems of the traditional outer wing section retracting into the inner wing section with heavy structural weight, rough transition between the two sections, poor shape maintenance of the airfoil surface, and low aerodynamic efficiency. . [0004] The invention provides a retractable shape-retaining wing, comprising: a fixed inner wing section 1, a telescoping mechanism 2, a wingtip shape-retainin...
