Analysis of a UAV propeller produced by various materials

Öz

Recently, Unmanned Aerial Vehicle (UAV) systems have started to attract great interest worldwide. With the orientation of the technology sector to this field, studies on UAV systems have gained momentum. Propellers, which are an important part of UAV systems, are of great importance to the propulsion system of the aircraft. Deformations that may occur, especially in propellers that are expected to have high strength, greatly affect flight safety. In this study, a two-bladed propeller model measuring 12 inches was created. The deformations caused by applying force to the created propeller model were examined. In this study, CFRP (Carbon Fiber Reinforced Polymer) and PLA (Polylactide Acid) materials were preferred. The mechanical properties of materials are defined in the ANSYS program. As a result of the force applied to the propeller model, the amounts of deformation occurring in CFRP and PLA materials have been obtained. At the end of the study, the difference between the properties of the two materials was discussed.

Son zamanlarda insansız Hava Aracı (İHA) sistemleri dünya çapında büyük ilgi görmeye başlamıştır. Teknoloji sektörünün bu alana yönelmesiyle İHA sistemleri üzerine çalışmalar hız kazanmıştır. İHA sistemlerinin önemli bir parçası olan pervaneler, uçağın tahrik sistemi için büyük önem taşımaktadır. Özellikle yüksek mukavemete sahip olması beklenen pervanelerde oluşabilecek deformasyonlar uçuş güvenliğini büyük ölçüde etkiler. Bu çalışmada 12 inç ölçülerinde iki kanatlı pervane modeli oluşturulmuştur. Oluşturulan pervane modeline kuvvet uygulanmasıyla oluşan deformasyonlar incelenmiştir. Bu çalışmada CFRP (Karbon Fiber Takviyeli Polimer) ve PLA (Polilaktik Asit) malzemeler tercih edilmiştir. Malzemelerin mekanik özellikleri ANSYS programında tanımlanmıştır. Pervane modeline uygulanan kuvvet sonucunda CFRP ve PLA malzemelerinde meydana gelen deformasyon miktarları belirlenmiştir. Çalışmanın sonunda iki malzemenin özellikleri arasındaki fark tartışılmıştır.
