The application provides a bird
flapping wing design method based on
momentum theorem analysis of factors influencing lift, which comprises the following steps: firstly, determining basic thrust and lift design constraints according to task requirements; secondly, according to the
momentum theorem, converting design parameters influencing the thrust and lift into contributions to the horizontal thrust and vertical lift of the
flapping wing, and screening the design parameters according to the constraints; considering the influence of
power consumption, determining corresponding design measures for reducing the
power consumption; analyzing the
realizability of the design measures to obtain the design parameters and corresponding design measures considering the
realizability; sorting the importance of the design parameters, optimizing the design measures of the corresponding design parameters, and obtaining the preliminary design scheme of the bird
flapping wing. The application converts complicated design constraints into simple requirements for the thrust and lift of the
flapping wing, greatly shortens the design time of the
flapping wing vehicle for different flight requirements, standardizes the overall design idea of the
flapping wing, and has high theoretical support and
engineering practical significance.
