Description

technical field [0001] The invention relates to the field of aerospace, in particular to a system and method for aerodynamic testing and flapping-wing flow field observation of a miniature flapping-wing aircraft. Background technique [0002] The wings of birds and insects have strong maneuverability, can take off at any time and fly vertically, can also perform rapid flight turns, and can hover continuously. The super flying ability of these flying creatures has gradually attracted human beings. of great concern. Micro-flapping-wing aircraft is a kind of bionic aircraft. It is a new concept aircraft based on bionics. It mainly generates lift and thrust to maintain flight by simulating the action of flapping wings of flying creatures. Compared with traditional fixed-wing and rotary-wing micro-aircraft, the micro-flapping-wing aircraft only needs to rely on periodic flapping movements to generate lift to maintain flight, and has better maneuverability and flexibility.

Problems solved by technology

At present, the existing experimental equipment is mainly used for the experimental research of conventional aircraft, and the experimental equipment for miniature flapping-wing aircraft is less and imperfect, and there are relatively few relevant experimental data of flapping-wing aircraft for reference, which limits the further research and development of

Moreover, most of the existing experimental equipment for micro-flapping-wing aircraft can only observe one of the aerodynamic characteristics of the micro-flapping-wing aircraft and the characteristics of the flapping-wing flow field, and cannot observe them at the same time
