The invention discloses a self-adaptive bionic piezoelectric scale rigid-flexible integrated resistance reduction skin, and belongs to the technical field of fluid bionic active resistance reduction, the self-adaptive bionic piezoelectric scale rigid-flexible integrated resistance reduction skin comprises a plurality of bionic piezoelectric scale rigid-flexible integrated resistance reduction devices, each bionic piezoelectric scale rigid-flexible integrated resistance reduction device comprises a piezoelectric vibrator and a bionic scale rear area, one end of the piezoelectric vibrator is fixedly connected with the bionic fish scale rear area in a glue joint mode, the piezoelectric vibrator comprises a flexible piece, a piezoelectric piece and a wire, one end of the flexible piece and the reference plane of the micro-aircraft are fixed in a flexible mode, the fixing position is A, and the other end of the flexible piece, namely the end, in glue joint with the bionic fish scale rear area, of the piezoelectric piece is fixed to the reference plane of the micro-aircraft. And the end is free. By the adoption of the self-adaptive bionic piezoelectric scale rigid-flexible integrated resistance reduction skin, the friction resistance of a near-wall laminar flow or turbulent flow boundary layer can be reduced when a micro-aircraft sails, the sailing speed of the aircraft can be increased, and the endurance mileage of the aircraft is increased.
