Abstract: A pull cord type turning mechanism for a butterfly-inspired flapping-wing aerial robot includes a motor, a cord reel, a cord reel gear, a potentiometer gear, a potentiometer, a control module, and a power supply. The control module is connected to the motor and the potentiometer. A rotary shaft of the motor is connected to the cord reel, the cord reel is coaxially connected to the cord reel gear, the cord reel gear is meshed with the potentiometer gear, and the potentiometer gear is connected to a rotary shaft of the potentiometer. The cord reel gear is provided with two cord grooves and two pull cords. One ends of the two pull cords are fixed in the two cord grooves, respectively, and the other ends thereof are fixed at the tips of front wings of two sides of the butterfly-inspired flapping-wing aerial robot, respectively.

Abstract: A flight test system for a flapping-wing aerial vehicle includes a host computer platform, a measurement mechanism, and a wind tunnel. The measurement mechanism is configured to mount a to-be-tested flapping-wing aerial vehicle prototype. The measurement mechanism includes an Euler angle controller, a flow angle controller, and a tripod. The flow angle controller is mounted on the tripod. The Euler angle controller is in transmission connection with the flow angle controller. The flapping-wing aerial vehicle prototype is detachably connected to the Euler angle controller by using a first connecting member. The host computer platform is in communication connection with the measurement mechanism and the wind tunnel, and is configured to control a wind speed of the wind tunnel and display a flight status of the flapping-wing aerial vehicle prototype in real time during test.
