Abstract
Topoloji optimizasyonu kullanılarak gerçekleştirilen hafif yapı tasarımları kütle özelliklerinden dolayı havacılık sektöründe ilgi görmektedir. Bu konuyla ilgili olarak yapılan çalışmalar incelendiğinde dayanım özellikleri değiştirilmeden yapı kütlesinin azaltılmasının hedeflendiği görülmektedir. Hava aracı çeşitlerinden biri olan ve kendine özgü uçuş özelliklerine sahip olmasından ötürü havacılık sektöründe kullanım alanı giderek artan döner kanatlı insansız hava araçlarının tasarımında yapı kütlesini azaltmak amacıyla topoloji optimizasyonu yöntemleri kullanılmaktadır. Bu yöntemlerin uygulanması sayesinde döner kanatlı insansız hava araçlarının dayanım-ağırlık oranı ve verimi artmaktadır. Bu çalışmada, döner kanatlı insansız hava araçlarının topoloji optimizasyonu konusunda literatürde bulunan çalışmalar araştırılmış ve elde edilen sonuçlar sunulmuştur. Yapılan araştırma sonucunda topoloji optimizasyonu yöntemlerinin hava aracı tasarımında yapı ağırlığını, yapı gerilimini ve kuvvete maruz kalan yapıdaki yer değiştirme değerini etkilediği tespit edilmiştir. Literatürdeki çalışmalarda araştırmacılar tarafından birim hücre yapısı içeren optimizasyon teknikleri ve birim hücre yapısı içermeyen optimizasyon teknikleri olmak üzere iki farklı strateji kullanıldığı görülmüştür.

Abstract
Lightweight structure designs using topology optimization attract attention in the aviation industry due to their mass properties. When the studies on this subject are examined, it is seen that the aim is to reduce the building mass without changing the strength properties. Topology optimization methods are used to reduce the structure mass in the design of rotary-wing unmanned aerial vehicles, which are one of the types of aircraft and are increasingly used in the aviation industry due to their unique flight characteristics. Thanks to the application of these methods, the strength-to-weight ratio and efficiency of rotary wing unmanned aerial vehicles increase. In this study, studies in the literature on topology optimization of rotary wing unmanned aerial vehicles were investigated and the results obtained were presented. As a result of the research, it was determined that topology optimization methods affected the structure weight, structure stress and displacement value in the structure exposed to force in aircraft design. In studies in the literature, it has been observed that two different strategies are used by researchers: optimization techniques that include a unit cell structure and optimization techniques that do not include a unit cell structure.
