The invention discloses a multi-wing flapping wing type bionic unmanned aerial vehicle, and relates to the technical field of aircrafts. The unmanned aerial vehicle comprises a fuselage, wings, an empennage and a driving system, wherein the driving system comprises a flapping mechanism, an attack angle adjusting mechanism and an empennage deformation mechanism. By increasing the number of the flapping wings and reasonably arranging the positions of the multiple pairs of flapping wings, the aerodynamic performance of the flapping-wing aircraft can be remarkably improved. Meanwhile, by designing the multi-degree-of-freedom empennage, the maneuverability of the aircraft can be further improved, the rear flapping wings can effectively utilize wingtip vortexes generated by flapping of the front flapping wings, so that the lift force is increased, the aerodynamic efficiency is improved, the problems that a traditional flapping wing aircraft is insufficient in lift force and low in aerodynamic efficiency are effectively solved, and the flapping mechanism is compact in structure, light in weight and low in cost. The system is simple in structure, high in reliability and easy to maintain, the empennage has four degrees of freedom, rigid decoupling of pitching, yawing and folding and unfolding of the empennage can be achieved, and therefore the reliability, stability and accuracy of the system are improved.
