The invention discloses a flap actuator of a large unmanned aerial vehicle and a mounting structure of the flap actuator. The actuator comprises an actuator shell, a rotary ball screw, a screw nut, a turbine and a worm are arranged in the actuator shell, a screw pair is formed between the ball screw and the screw nut, the screw nut is fixedly connected with the turbine, the turbine is meshed with the worm, a knuckle bearing is arranged at the front end of the ball screw, and the actuator shell is arranged on the universal ring mechanism. The mounting structure comprises the flap actuator of the large unmanned aerial vehicle and further comprises a wing framework and a flap framework, the flap framework slides along a flap sliding rail on the wing framework, the universal ring mechanism is mounted on the wing framework, and the flap actuator is connected with the flap framework through a knuckle bearing. The invention has the following beneficial effects: 1, higher acting force can be output; 2, the actuating stroke is long; the structure is simple and reliable, and the weight is light; 4, the force transmission path of the actuator is ensured to be direct through a universal mechanism; 5, a single transmission chain is adopted, transmission is reliable, and actuation is accurate; and 6, the locking function is achieved.
