Configuration Synthesis And Analysis Of Flexible Variant Wings

With the development of the aviation industry, the speed of aircraft flight continues increasing. At the same time, requirements of aircraft structural design and stiffness improve, too. For now, the aircraft wing design is based on the shape of the wing which is optimized for a particular flight condition. Clearly, this kind of design limits the aircraft performance. But, the morphing wing can take the use of control surface deflection and achieve continuous flexible deformation of the wing and change the shape of the wing by controlling the internal wing linkage components. Therefore, we can make changes of the external wing with atmospheric changes, the angle of attack and different flight conditions, etc., with that, we can ensure the aerodynamic performance. Therefore, this kind of design has broad prospects for development.According to the edge of the track changes require flexible wing, this article starts with configuration graph theory, designs a kind of single degree of freedom with the whole R pairs flexible trailing edge mechanism. In this paper, Adams software is used for agencies kinematics simulation. Matlab software is used for the kinematic modeling agencies, and analyzing displacement, velocity, acceleration changes of key points. We compared two methods guidelines to verify the rationality of the movement. Fluent software is used for analyzing lift coefficient, drag coefficient, lift-drag ratio, etc., aerodynamic performance, which validated that it has better performance than the traditional wing. Lagrangian method is used for dynamic modeling mechanism, and ready for the further work. We used Simulink function modules for system modeling and verified deflection angle range of the mechanism. At last, we used multi-objective genetic algorithm to optimize the trajectory of the mechanism with ensuring the accuracy of the mechanism. And we used GUI for the whole system integration.
