DESIGN AND MODELLING OF NANO AERIAL VEHICLE HUMMINGBIRD MECHANISM ON HOVER FLIGHT

In nature, there are thousands of flapping insects and flying bird’s species. Each one has spectacular flight stability, dynamic and operates in high diversity of flight speed and mission. Each one has superior effectiveness and high efficiency. This paper relates with design and model of an efficient hummingbird mechanism during hovering flight. The proposed mechanism represents new and different concept for point of Nano aerial vehicle’s (NAV’s) mechanism design. In this study, flapping wing tip path for hummingbird was generated from morphological experiment data’s. Slider crank mechanism was designed to be an effective mechanism and same motion with path of hummingbird and analyzed on Simulink with driving crank flapping frequency as 25 Hz. During hovering, forces occurring on designed mechanism were calculated. The system modeled on MATLAB using of Sim-mechanics Toolboxes.

NANO HAVA ARACI SİNEKKUŞU MEKANİZMASININ HAVADA ASKIDA KALMA HAREKETİNİN TASARIMI VE MODELLENMESİ

Doğada kanat çırparak uçan binlerce böcek ve kuş türü vardır. Her biri belirli uçuş kararlılığı, dinamiği ve geniş zarf aralığında uçuş hızı ve göreve sahiptir. Her biri süper efektif ve yüksek verimliliğe sahiptir. Bu makale askıda kalma hareketi boyunca verimli bir Sinekkuşu mekanizmasının tasarımı ve modellenmesi ile ilgilidir. Önerilen mekanizma Nano insansız hava araçlarının mekanizma tasarımı açışından yeni ve farklı kavram ortaya koymaktadır. Bu çalışmada, Morfolojik deneysel verilerden Sinekkuşunun kanat ucundaki izlediği yörünge oluşturuldu. Efektif olduğu ve Sinekkuşunun yörüngesiyle aynı hareketi yaptığı için kaydırıcı krank mekanizması tasarlandı ve askıda kalma hareketinde Sinekkuşunun krankı 25 Hz frekans ile sürülerek Simulink üzerinden analiz edildi. Askıda kalma hareketi boyunca, tasarlanan mekanizma üzerindeki kuvvetler hesaplandı. Sistem MATLAB üzerinden SimMechanics aracı kullanılarak modellendi.
