Analysis of development status of multi-section morphing wing technology
The comprehensive aerodynamic performance in the flight envelope and the balance of the maneuverability and stability requirements of the aircraft can be improved by coordinated deflection of inner and outer wing sections of multi-section morphing wing.In view of the characteristics of multiple combined deformation modes provided by multi-section morphing wing,the typical morphing structures are analyzed.The research status and achievements of multi-section morphing wing are summarized in key technical fields such as intelligent material structure design,aerodynamic characteristics analysis,stability analysis and flight control system design.The technical difficulties and the key problems that the multi-section morphing wing is applied into the large size UAVs are pointed out,which can provide a reference for the research of key technologies of multi-section morphing wing and the development of morphing aircraft in the future.
