Abstract: Canard rotor wing（ CRW） UAV has the flight characteristics of both the helicopter and fixedwing aircraft. Mechanism model is constructed according to its flight characteristic in cruising mode,and the flight mechanic model identification is studied with the combination of frequency domain identification algorithm. Frequency sweep flight technique is used to obtain the flight data of canard rotor wing unmanned aerial vehicle near its cruising working condition,and frequency response is optimized with a new method for combining the results of multi-input frequency-response analyses obtained from a range of spectral windows into a single one. And then the transfer functions of both longitudinal and lateral channels are acquired. It indicates that the model can reflect dynamic characteristics of the CRW UAV and can be used in the design of the flight control system through the verification of the model and real flight data in the time domain.
