Flapping wing flight is the oldest flight mode in nature.Comparing to fixed wing and rotor craft wing flight mode,it can quickly take off,acceleration,hovering,with high mobility and flexibility.In recent years,the micro air vehicle has become a hot topic in the field of aviation,and it can be used as the object of our study.For birds,the lifting mechanism of the single wing flight has made considerable technological achievements,but for the micro flight insect,research is still in its infancy.Micro flight insects show great superiority in flapping flight of insects,mainly in:they can be easily implemented before flying,climbing,gliding and steering mode of flight;Micro flight insect has a low Reynolds number of the unsteady mechanism combined with traditional flight mechanism into the best way of flying,so for the researches on the mechanism of the micro flapping wing insect and the analysis of the different flight mode choice for the application of micro flapping wing flight vehicle is of great significance.Firstly,a brief concept of MAV,characteristics and ground application prospect are introduced,the current domestic and foreign theory and prototype research status and achievements are summarized,the key problems and difficulties of flapping-wing micro vehicle(FLMAV)are analyzed.Secondly,I analyzes the wings flapping process of insects,study the mechanism of insect flight,the high lift mechanism of insect flapping wing flight are explained using unsteady aerodynamics.Learned several kinds of passive drive thorax mechanism and and a new-type cantilever structure was presented according to lab's condition.In addition,Based on the unsteady aerodynamics force model,the dynamic model of dragonfly flapping-wing air vehicle is established.COMSOL was used for dynamic simulation,which was aimed to analyze the characteristic of dynamics and the result proved that the derivation of the model was correct.Lastly,I made a prototype for the experiment and recorded its motion by high speed camera.The motion shows that bionic wing is able to achieve its function,and this design is reliable.
