Aerodynamic efficiency analysis of variable morphing wings

Abstract

In this paper, variable wing and/or winglet concepts are investigated. The impetus for the work was to identify and optimize wing and winglets to enhance the aerodynamic efficiency of a morphing aircraft. The analysis is based on changing sweep angle and wing-tip twist together with cant angle morphing (Γ = 0° - 45° φ = −10°- 10° and Λ = 0° - 30°). A variety of cases are examined through an aerodynamic analysis tool (VLM) comparing with baseline sweep wing configuration. As a result, significant improvements in flight characteristics are observed by adapting the required angle to receive optimum performance benefits.
