The invention discloses a wind tunnel test unmanned aerial vehicle attack angle automatic adjusting system. The automatic adjusting system comprises a stepping motor, a motor controller, a lead screw,a positioning support, an aircraft supporting rod, an angle adjusting sliding block, an angle adjuster, a sliding groove, a control box, a lead screw sliding block and a base. The lead screw slidingblock is installed on the lead screw, and the lead screw is installed on the motor controller and connected with the stepping motor. The unmanned aerial vehicle is fixed to the aircraft supporting rod, the aircraft supporting rod is installed on the angle adjusting sliding block, the angle adjusting sliding block is hinged to the angle adjuster, and the angle adjuster is fixed to the lead screw sliding block. The front end of the positioning support is hinged to the aircraft supporting rod, and the rear end of the positioning support is connected with the sliding groove; the base is fixed to the lower end of the sliding rail; and the control box is fixed to the back of the sliding rail and internally provided with a power source, a single-chip microcomputer and a touchpad. The attack angleis adjusted under the action of the airplane supporting rod, the angle adjusting sliding block and the angle adjuster; the movement distance of the lead screw sliding block is calculated through thesingle-chip microcomputer, and the stepping motor is controlled to make the gravity center of the unmanned aerial vehicle located in the wind field middle section.
