Problems solved by technology

At present, the established flapping-wing aircraft simulation model can only simulate the state of the flapping-wing aircraft flying at a constant speed, but cannot realize the composite flight state of flapping-gliding similar to birds. Therefore, the flapping-wing aircraft established in the prior art The simulation model of the aircraft has a limited degree of simulation, which is not conducive to more accurate research on the flight performance of the flapping wing aircraft
