Flexible Trailing Edge Module for Wings with Variable Trailing Edge Camber

Abstract

A flexible trailing edge module used for a wing with variable camber at the trailing edge, comprising: an external positioning hole (11) connecting the flexible trailing edge module with an external wing, an external positioning slot (2) for adjusting the direction of the flexible trailing edge module, and fixing The fixing hole (3) of the flexible wing rib (6), the steering gear frame mounting groove (10) for adjusting the position of the steering gear (4), and the chute (8) for fixing the movement track of the lower surface of the flexible wing rib (6). The present invention adopts a modular design, and connects the flexible rib (6) and the steering gear (4) through the internal slot of the connecting frame (1) to form a flexible trailing edge module, and then through the external slot of the connecting frame (1) It is connected with the wing structure and used for related tests of trailing edge variable camber wings. The modular design method has the advantages of simple structure, high reliability, low cost and convenient replacement, and is suitable for trailing edge variable camber wings with various structures and deformation modes.

Description

technical field [0001] The invention relates to a flexible trailing edge module for a trailing edge variable camber wing, and a trailing edge variable camber wing with the flexible trailing edge module. Background technique [0002] Modular design refers to dividing and designing a series of functional modules on the basis of functional analysis of products with different functions within a certain range or products with the same function, different performance, and different specifications. Different products can be formed through the selection and combination of modules. , to meet the different needs of the market design methods. [0003] Adaptive wing refers to a wing that can automatically change geometric parameters according to flight conditions to obtain optimal performance during flight, that is, without conventional ailerons, flaps, slats and spoilers, the wing itself can Flexibly bend to desired position. Adaptive airfoils are mainly divided into two deformation ...

AI Technical Summary

Problems solved by technology

In this way, it is necessary to design a separate fixture to fix and test the flexible trailing edge, and when connecting with the external structure of the wing for the overall test of the trailing edge variable camber wing, it is necessary to redesign the corresponding docking scheme for connection, so The design cycle of the flexible trailing edge is longer and the design cost is higher
