Flexible trailing edge module for trailing edge variable camber wing

Abstract

The invention discloses a flexible trailing edge module for a trailing edge variable camber wing. The module comprises an external positioning hole (11) used for connecting the flexible trailing edgemodule with the external wing, an external positioning groove (2) used for adjusting the direction of the flexible trailing edge module, a fixing hole (3) used for fixing a flexible wing rib (6), a steering engine frame mounting groove (10) used for adjusting the position of a steering engine (4), and a sliding groove (8) used for fixing the lower surface movement track of the flexible wing rib (6). The modular design is adopted; the flexible wing rib (6) and the steering engine (4) are connected through the internal hole groove of a connecting frame (1) to form the flexible trailing edge module, and then the flexible trailing edge module is connected with the wing structure through the external hole groove of the connecting frame (1) to be used for related tests of the trailing edge variable camber wing. The modular design method and flexible trailing edge module are simple in structure, high in reliability, low in cost, convenient to replace and suitable for trailing edge variable camber wings of 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
