According to the invention, tools and parts such as the electronic scale and the high-speed camera are utilized, the manufacture is simple, higher force and motion measurement precision can be easily obtained, aerodynamic force, wing motion and deformation measurement of the flapping-wing micro air vehicle in the overall design stage can be quickly completed, and data support is provided for aerodynamic parameter optimization.

Description

technical field [0001] The invention relates to the field of flapping-wing micro-aircraft, in particular to a platform for synchronously measuring average lift and wing motion of a flapping-wing micro-aircraft. Background technique [0002] Since the 1990s, with the continuous maturity of traditional aircraft design technology and the great progress of microelectronics technology, micro air vehicles have been proposed and developed rapidly. With the characteristics of small size, light weight and strong maneuverability, micro air vehicles have broad application prospects in national security and national economic construction, and are suitable for investigation, exploration and rescue assistance in complex environments. With the continuous exploration of natural biological flight, bionic design has been more and more applied to the field of micro-aircraft, and flapping-wing micro-aircraft that imitate the flight of insects have begun to appear. [0003] The lift and lift ge...
