The invention discloses a foldable unmanned aerial vehicle wing based on multistable characteristics, which comprises a main wing, a folding structure, a flexible skin and a supporting piece fixed tothe vehicle body. The folding structure comprises a multistable composite cylindrical shell, a first memory alloy and two first stand columns. One end of the multistable composite cylindrical shell isfixed with the main wing; the other end of the multistable composite cylindrical shell is fixed with the supporting piece; the lower ends of the two first stand columns are fixed to the two oppositesides of the multistable composite cylindrical shell correspondingly. The two ends of the first memory alloy are fixed to the upper ends of the two first stand columns respectively, the two ends of the first memory alloy are electrically connected with heating circuits respectively, the folding structure is wrapped with the flexible skin, and the two ends of the flexible skin are fixed to the folding structure, the main wing and the supporting piece respectively. The foldable unmanned aerial vehicle wing based on the multistable characteristics has the advantages of being simple in folding structure, small in weight, stable in folding and unfolding state and the like.
