The invention discloses a full-flexible body unmanned aerial vehicle based on the coanda effect. The full-flexible body unmanned aerial vehicle comprises a flexible body assembly, an annular propeller, a variable structure mechanism, a turbojet engine, an oil tank, a storage battery and a controller. The whole flexible body assembly is in a streamline wing shape and comprises an upper deformation body, a lower deformation body and a peripheral supporting body, a plurality of flexible cables are arranged in the upper deformation body and the lower deformation body at intervals, a plurality of annular propellers are symmetrically arranged on the two sides of the flexible body assembly, and each annular propeller is connected with a variable structure mechanism. Air cavities are formed in the side walls of the annular propellers, annular slits are formed in the inner side faces of the annular propellers, the output end of the turbojet engine is connected with the input end of the high-pressure manifold, and the high-pressure manifold is provided with a plurality of output ends communicated with the air cavities of the annular propellers. The endurance and load capacity of the unmanned aerial vehicle are improved, noise is reduced, more complex appearance structure changes can be achieved, and the unmanned aerial vehicle can obtain better aerodynamic characteristics in the specific flight mission stage.
