Aerodynamic efficiency analysis of variable morphing wings

Bu makalede değişken kanat ve/veya kanatçık kavramları incelenmiştir. Çalışmanın amacı, morphing uçaklarının aerodinamik verimliliğini artırmak için kanatları ve kanatçıkların değişim açılarını belirlemek ve optimize etmekti. Analiz, değişen tarama açısına ve kanat ucu bükümüne ve ayrıca eğim açısı biçim değiştirmesine (Γ = 0° - 45° φ = -10°- 10° ve Λ = 0° - 30°) dayanmaktadır. VLM analiz yöntemi kullanılarak farklı kanat varyasyonları denenmiştir. Sonuç olarak, optimum performans faydalarını elde etmek için gerekli açı uyarlanarak uçuş özelliklerinde önemli gelişmeler gözlemlenmiştir

Aerodynamic efficiency analysis of variable morphing wings

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.
