In this paper, effectiveness of twist varied wing configurations for aircraft control and performance is described. The primary variables investigated involved changing the wing twist angle of a comparable Airbus A320 wing structure by identifying the ideal angle of twist. The aerodynamic performance and control of the morphing wing is characterised in AVL (Athena Vortex Lattice Method). In order to better understand the aerodynamic performance and control of twist morphing wing for diverse flight regimes, predetermined values of twist (-8°< ϕ <8°, in steps of ±2°) were examined. The results from this work indicate that if morphing wings were employed on aircraft, performance benefits could be achieved.
In this paper, aerodynamic performance benefits of morphing unmanned aerial vehicle’s wing concepts are investigated. A Predator MQ-1B with variable wing structure was utilized for this study. The concept consists of variable twist (-10°< θ <10°, in steps of ±2.5°) and wing sweep (0°< θ <30°, in steps of +10°) to illustrate morphing wing’s performance benefits. All computations were performed with Athena Vortex Lattice modelling with varying degrees of twist and sweep angle considered. The results obtained from this work show that if morphing wings adapted to the Predator MQ-1B, it will provide significant performance benefits and also offer a great opportunity to reduce fuel consumption.
This article describes the performance benefits of variable winglet configurations. The primary variables investigated involved varying the winglet twist and dihedral angle of a comparable Airbus A330-300 wing structure. Numerical studies have been carried out in AVL (Athena Vortex Lattice Method). In order to illustrate the aerodynamic benefits of morphing winglet concepts for different flight regimes, values of twist (-10°< θ <10°, in steps of ±2.5°) and values of dihedral (-90°< θ <90°, in steps of ±15°) were designed and numerically investigated. The results obtained from this work indicate that by carefully adjusting morphing winglets on air vehicles (Airbus A330-300), the aerodynamic performance benefits could be achieved.
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
