The invention discloses a bionic 
hummingbird aircraft; a high bionic design is adopted, the unsteady 
aerodynamics theory of 
hummingbird micro 
flapping-wing flight is explored, and a simplified model for realizing the movement law of a vertical take-off and landing and hovering 
flapping wing aircraft is established. An ultra-light 
flapping-wing 
structure based on a five-link 
crank rocker and an ultra-light 
flapping wing attack angle adjusting structure with a principle similar to a helicopter variable 
pitch principle are designed. In accordance with a modular and 
integrated design concept, bionic 
hummingbird aircraft subsystems such as a 
power transmission system and a flight control electronic 
system are researched and developed, and a hummingbird 
flapping wing prototype vehicle capable ofrealizing switching of vertical 
takeoff and landing and hovering flat flight is completed. Based on the design idea of '' flying early and flying more'', an experimental method is used to optimize aniterative principled sample 
machine to realize flight maneuvers such as hovering and forward flying of the bionic hummingbird aircraft to achieve the performance requirements of flexible detection. In the future, the bionic hummingbird aircraft can realize multi-bird cluster detection, and complete the low-altitude domain reconnaissance missions in a whole combat area through collaborative control and a bird-
flock-like intelligent 
algorithm.
