Research on Aerodynamic Characteristics of Morphing Aircraft with a Telescopic Wing

Abstract

A kind of morphing aircraft based on the concept of telescopic wing was designed in this paper. With the numerical calculation, it compared the aerodynamic characteristics before and after the morphing of the aircraft, and analyzed the relationship of the aircraft aerodynamic coefficient to its length, angle of attack and flight Mach number. The result showed that through morphing the movable wing, the aircraft can significantly change the lift, drag and other aerodynamic characteristics; the morphing aircraft can satisfy the dual task requirements of low-speed cruise and high-speed attack. Compared with the traditional aircraft in fixed shape, it had a better aerodynamic performance.
