Classification features of adaptive wing designs: history of creation, application experience and advanced developments

An overview of the developments of Russian and foreign scientists in the field of designing adaptive wings is presented. The work examines historical periods of development and improvement of methods for transforming the wing of aircraft. Classification features of adaptive wings of aircraft are identified, a detailed classification of transformable wings according to purpose (stationary and mobile) and design features (option and method of changing configuration and shape) is proposed. The results of testing finished structures and prototypes are shown. Patents for advanced adaptive wing designs are described.
