Technical Field

The invention relates to a test platform for the performance of a flexible skin of a trailing edge variable camber wing.

Background

The self-adaptive wing is a wing which can automatically change the geometrical parameters of the wing according to the flight condition in flight so as to obtain the optimal aerodynamic performance, the wing has no conventional rigid deflection ailerons, flaps, slats and spoilers, and the wing can achieve the optimal target appearance through deformation according to task conditions. The deformation mode of the self-adaptive wing mainly comprises out-of-plane deformation and in-plane deformation, wherein one main form of the in-plane deformation is trailing edge bending, and the mode changes the pressure distribution on the surface of the trailing edge of the wing by mainly changing the bending of the trailing edge of the wing, so that the optimal target shape required by a task is achieved.

The trailing edge bending wing is continuously researched and developed in recent years because of unique aerodynamic performance advantages and wide flight envelope adaptability, but the existing research on the flexible skin of the trailing edge bending wing mainly focuses on the single performance of the flexible skin or the selection and size design of the flexible skin material according to the corresponding trailing edge bending wing structure, however, the research and design method can only simply test the performance of the flexible skin or needs to design and manufacture a complete trailing edge bending wing structure, so that the test is insufficient or a large amount of time and cost are consumed, and the method is not suitable for the test of the performance of the flexible skin of the trailing edge bending wing with different types, sizes and driving modes.

In addition, a novel flexible skin of a trailing edge variable camber wing often needs to be subjected to corresponding deformation quality tests and deformation capability tests in combination with a specific trailing edge variable camber wing structure to determine the performance and the applicability of the flexible skin. Therefore, the complete trailing edge bending wing structure needs to be designed independently to test the performance of the flexible skin of the trailing edge bending wing, and when the size of the flexible skin of the trailing edge bending wing changes, the corresponding trailing edge bending wing structure needs to be redesigned to test, so that the test period of the flexible skin of the trailing edge bending wing is long, and the test cost is high.

Therefore, a platform suitable for testing the performance of the flexible skin of the trailing edge variable camber wing, which is applicable to different driving modes, different materials, different sizes, simple to use, convenient to replace and low in cost, needs to be developed so as to test the performance of the flexible skin of the trailing edge variable camber wing in a wider application range.
