Simulation modeling method for composite flight strategy of flapping wing air vehicle

Abstract

The invention provides a simulation modeling method for a composite flight strategy of a flapping wing air vehicle. The method comprises following steps: obtaining basic parameters of a flapping wing air vehicle under study; establishing an aero-dynamic model; establishing a dynamic model; describing composite flight process; establishing the relation between flight power and flapping power and flapping amplitude to obtain a flight energy consumption calculation model; establishing a control rate model; linking and sorting the aero-dynamic model, the dynamic model, a composite flight planning model, the flight energy consumption calculation model and the control rate model to establishing a final simulation model. The advantages of the method are: simulation technicists can efficiently use the Matlab/Simulink simulation environment to establish a composite flight simulation model of a flapping wing air vehicle and determine composite flight ability of the flapping wing are vehicle through analyzing simulation results of different flight strategies, and find an optimal flight strategy; the method is of instructive importance to flapping wing air vehicle engineering improvement.
