Embodiment Construction
[0052] see figure 1 — Figure 8 , a design method for deformable wing trailing edge based on "knuckle-style" rigid-flexible coupling. Include the following steps:
[0053] Step 1: Genetic algorithm optimization of open-chain three-knuckle mechanism
[0054] a. The rigid mechanism at the trailing edge of the wing is a Watt-type six-bar mechanism, and its theoretical model is as follows image 3 As shown in the figure, the AB rod, BC rod, and CM rod are open-chain three-knuckle mechanisms. The degree of freedom of the open-chain three-bar mechanism is not 1, and the movement is uncertain. Therefore, it is necessary to pass through the AE rod, ED rod, and FG rod. The three links of the open chain are closed, and the degree of freedom of the whole set of rigid mechanisms is 1 after closing, which can ensure the deformation angle of the wing. The theoretical model of the driving mechanism is as Figure 7 As shown, the driving trailing edge mechanism adopts the slider crank mec...
