The mechanical characteristics analysis of the telescopic wing with adaptive driving mechanism

The deflection of the high aspect ratio telescopic wing is inevitable under aerodynamic force. It is of great significance to ensure that the internal mechanism can exercise smoothly in the deformation state. A telescopic mechanism that can adapt the deflection of the telescopic wing is proposed, and its mechanical analysis is carried out. Then, the rigid-flexible coupling model of the whole mechanism, which considers the wing-bending deformation, is obtained. Finally, the prototype of the telescopic mechanism is developed, and the proposed model is verified by experimental results. The results show that the proposed adaptive driving mechanism can effectively realize the morphing process under heavy load without stagnation and can provide the theoretical basis and technical support for the design of a large aspect ratio telescopic wing.
