The invention discloses a small wind tunnel experiment system for micro ornithopter research. The small wind tunnel experiment system comprises a wind tunnel body, a fan, an ornithopter model adjusting module, an acquisition module and a control module. The wind tunnel body is a straight-flow type wind tunnel and is suitable for the experimental research on the relationship among the flapping wing motion, deformation and aerodynamic force of the miniature ornithopter; a flight attack angle of the ornithopter model can be adjusted through an ornithopter model adjusting module, the flapping frequency of the ornithopter model can be controlled by controlling the working voltage of the ornithopter model, and the airflow velocity can be adjusted through the fan. Through the acquisition module, the air flow parameters in the wind tunnel, the stress of the ornithopter and the deformation images of the wings of the ornithopter can be acquired in real time, subsequent data analysis is carried out, and the system can be used for aerodynamic research of micro ornithopters and is also suitable for aerodynamic research of micro rotorcrafts and fixed-wing aircrafts.
Description
technical field [0001] The invention relates to the field of miniature flapping-wing aircraft, in particular to a small-scale wind tunnel experiment system used for the research of miniature flapping-wing aircraft. Background technique [0002] Flying objects in nature, such as insects and birds, realize autonomous flight by means of flapping wings. In the range of Reynolds number of micro-aircraft, flapping-wing aircraft have better stability than fixed-wing and rotary-wing. Therefore, micro-flapping-wing based on insect bionics Aircraft research has developed rapidly. Different from fixed wings and rotors, micro-orthopting-wing aircraft rely on flapping motion and deformation of flexible film wings to generate lift and propulsion. The analysis of the relationship between the dynamics is not very targeted. [0003] The wind tunnel experiment platform is mainly used for aerodynamic experiments, using the principle of relative motion, generally the research model is fixed, ...
