In recent years,the demand for hybrid aquatic-aerial vehicles(HAAVs)in civil and military fields has grown rapidly. Its key technologies include trans-media power technology,watertight technology,overall configuration design,cross-media control,etc. In view of the morphing wing technologies that affect the overall scheme,the possible morphing wing technologies of fixed-wing transmedia vehicles are classified from a theoretical point of view,and the morphing wing technologies used in the existing vehicle design schemes and exploration practices at home and abroad are studied and summarized. On this basis,the technical prospect of the morphing wing technologies for hybrid aquatic-aerial vehicles is proposed,which provides a certain design basis for the overall scheme of the subsequent hybrid aquatic-aerial vehicles.
