The invention discloses a flapping-rotating wing with an attack angle control device, and belongs to the technical field of micro aerial vehicles. The flapping-rotating wing comprises a flapping-rotating wing body, the attack angle control device and a limiting device, wherein the flapping-rotating wing body comprises a main beam, a short beam, an inclined beam and a wing membrane; the attack angle control device and the limiting device act commonly and comprise two modes, one mode is that the attack angle control device and the limiting device comprise a baffle plate, a limiter and an attack angle controller, a groove is formed in the attack angle controller, the baffle plate moves up and down in the groove, and the limiter is used for controlling the movement range of the baffle plate; the other mode is that the attack angle control device and the limiting device comprise a deform sheet and a limiting girder, the thickness of the deform sheet is changed or the distance from the connecting point of the short beam and the inclined beam to the main beam is adjusted to control the wing section attack angle when the flapping-rotating wing body flaps upwards, and the limiting girder is used for limiting the deformation of the flapping-rotating wing when the flapping-rotating wing flaps downwards; the attack angle of the flapping-rotating wing during flapping is controlled, while positive lifting force is maintained, negative lifting force is effectively reduced, and thus, average lifting force of the micro aerial vehicle with the flapping-rotating wing is increased and the energy utilization rate of the aerial vehicle is increased.
