Investigation of Structural Performances of Composite Materials Reinforced by Glass and Carbon Fibers Used on Unmanned Aerial Vehicles Using Numerical Simulations

Öz

Composite materials are often preferred in many industries such as aviation and automotive since they have many advantageous properties such as high specific strength, high corrosion resistance and ability to absorb vibration. In this study, a research for structural behaviour is theoretically done on an unmanned aerial vehicle wing composed of composite materials and metallic materials. Two different wing geometries are considered in the study. The first of these is the wing geometry without control surfaces that are flap and aileron. This wing geometry is mentioned as Model 1. The second of these is the wing geometry with flap, aileron and related components. The second wing geometry is mentioned as Model 2. New wing models composed of different material systems are created and analysed under different loads in order to develop reference wing model. These loads are the loads calculated under level flight cruise conditions and maximum static pressure loading conditions. In this way, the optimum configurations of the wing models are obtained.

Öz

Kompozit malzemeler yüksek özgül mukavemet, korozyon direnci, titreşim sönümleme kabiliyeti gibi birçok avantajlı özelliğe sahip oldukları için başta havacılık ve otomotiv olmak üzere birçok sektörde sıklıkla tercih edilmektedirler. Bu çalışma kapsamında kompozit malzeme ve metalik malzemelerin birlikte oluşturduğu bir insansız hava aracı kanadının yapısal davranışı teorik olarak incelenmiştir. Çalışmada iki farklı kanat geometrisi üzerinde durulmuştur. Birincisi, flap ve aileron bulundurmayan yekpare bir kabuğa sahip kanat geometrisidir. Bu kanat geometrisi Model 1 olarak isimlendirilmiştir. İkincisi ise üzerinde flap ve aileron kontrol yüzeylerini ve ilgili tüm yapısal elemanlarını barındıran kanat geometrisidir ve bu kanat geometrisi ise Model 2 olarak adlandırılmıştır. Referans alınan teorik kanat modelini yapısal olarak geliştirmek amacıyla farklı malzeme sistemlerinin kullanıldığı yeni teorik kanat modelleri oluşturulmuştur. Bu modeller yatay uçuş seyir şartları ve maksimum statik basınç yükü altında yapısal analizlere tabi tutulmuş en uygun konfigürasyonlar ortaya konulmuştur.
