Embodiment Construction

[0021] This embodiment is a high-precision light-weight controllable telescopic wing mechanism.

[0022] refer to Figure 1 to Figure 6 , the high-precision light-weight controllable telescopic wing mechanism of this embodiment includes a fixed wing 1, a middle wing 2, an outer wing 3, an inner four-link 4, an outer four-link 6, a driver 7, and a double-hole connecting plate 5,

[0023] The fixed wing 1 is the root of the wing, and the inner four connecting rods 4 are placed inside the fixed wing 1. One end of the fixed wing 1 is closed and the other end is open, and the closed end of the fixed wing 1 is fixed on the body. The middle wing 2 is installed between the fixed wing 1 and the outer wing 3, the chord length is 90% to 95% of the chord length of the fixed wing 1, the outer four-link 6 is placed inside the middle wing 2, the closed end of the middle wing 2 is connected to the fixed wing 1. The open end is fixed along the span direction through the double-hole connecting...

Abstract

The invention discloses a high-precision and light-weight controllable telescopic wing mechanism. Deformation of an intelligent material is controlled by programming to realize expansion and contraction of drivers; when all the stages of the drivers contract, a four-connection-rod mechanism extends; a middle wing extends out of a fixed wing, and an outer wing extends out of the middle wing, so that extension of an overall wing is realized; when the drivers extend, the four-connection-rod mechanism is shortened; the outer wing returns into the middle wing, and the middle wing returns into the fixed wing, so that contraction of the overall wing is realized. Components in the mechanism are rigid elements in rigid connection, so that transmission is stable and accurate. Under the action of a control system, a telescopic wing can precisely realize expansion and contraction; the mechanism is light in mass, high in transmission speed and low in error; when a pneumatic appearance requirement of an aircraft in different stages is met, the total mass and the safety of the aircraft cannot be greatly affected; the telescopic wing controls the deformation of the intelligent material through programming, so that random extension and high-precision controllable contraction of the wing are realized, and an effect of controlling an element can be achieved.

Description

technical field [0001] The invention belongs to the technical field of aviation applications, and in particular relates to a high-precision, lightweight, controllable telescopic wing mechanism. Background technique [0002] In the existing published technical literature "Structure Design and Vibration Experimental Research of Stretchable Wing" (Journal of Dynamics and Control, No. 4, 2011), the actuating mechanism of the stretchable wing was optimally designed by using 3D modeling software. Completed the overall structure design of the retractable wing structure and each subsystem structure, carried out vibration experiment research based on the retractable wing experimental device, and analyzed in detail the lateral direction of the retractable wing under different extension and contraction speeds. Vibration response, the experimental results have a certain theoretical guiding effect on engineering applications. The actuating mechanism of the retractable wing designed in t...
