Embodiment Construction

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be described in more detail below in conjunction with the drawings in the embodiments of the present invention.

[0030] like figure 1 The active flexible stretchable truss structure shown includes an upper panel 1 , a lower panel 2 , a telescopic truss 3 , a spring 4 and a controllable alloy wire 5 .

[0031] The upper panel 1 and the lower panel 2 are arranged opposite to each other. It should be noted that although the upper and lower panels shown in the figure are regular planes and arranged in parallel, the upper panel 1 and the lower panel 2 can be metal plates with some curvature, and the upper panel 1 and the lower panel 2 can be non- parallel state, but it is necessary to ensure that the telescopic truss 3 can be arranged between the upper panel 1 and the lower panel 2, and that the teles...

Abstract

The invention relates to an active flexible telescopic truss structure, and belongs to the technical field of morphing aircraft structural design. The structure comprises a first panel and a second panel, a telescopic truss, springs and controllable alloy wires, wherein the first panel and the second panel are opposite to each other; the telescopic truss is arranged between the first panel and thesecond panel and can be stretched between the first panel and the second panel; the springs are perpendicular to the movement direction of the telescopic truss, and are respectively connected to thefirst side and the second side of the telescopic truss; the controllable alloy wires are respectively arranged on the first side and the second side of the telescopic truss; and stretching of the telescopic truss can be controlled through the control of the controllable alloy wires. The active flexible telescopic truss structure is driven through the controllable alloy wires (shape memory alloy wires), drives angles between telescopic trusses to change, and achieves the purpose of telescopic deformation.

Description

technical field [0001] The invention belongs to the technical field of variant aircraft structure design, and in particular relates to an active flexible stretchable truss. Background technique [0002] Through intelligent design and control, variant technology can adaptively change important parameters such as wing shape, thickness, and camber according to tasks and environments, so that the aircraft can obtain ideal aerodynamic characteristics in different flight states, taking into account the aircraft's The use performance at different speeds and solving the contradictions in the aerodynamic layout design of modern aircraft play a very important role in improving the overall performance of military aircraft. [0003] Currently, the main difficulties faced by variant aircraft design technology include the following aspects: [0004] 1) Solve the contradiction between in-plane deformation and out-of-plane bearing of the variant structure [0005] Since the variant struct...
