Bir İnsansız Hava Aracı Pervanesi İçin Açık Kaynaklı Bir Aerodinamik Şekil Optimizasyon Uygulaması

Askeri, tarım ve özel amaçla kullanılan insansız hava araçları günümüz şartlarında insanlı hava araçlarına göre daha popüler ve fonksiyonel olmaktadır. İnsansız hava araçları genellikle pervane tahrikli bir itki sistemi kullanmaktadır. Bu sistemlerin performanslarının iyileştirilmesi için aerodinamik şekil optimizasyonu hayati önem taşımaktadır. Bu nedenle bu çalışmada, bir açık kaynaklı, Hesaplamalı Akışkanlar Dinamiği (HAD) tabanlı bir optimizasyon döngüsü (HAD çözücüsü, optimizasyon çözücüsü, serbest şekil değiştirme aracı ve çözüm ağı üreticisi birlikte çalışmakta) tasarlanarak, bir generik insansız hava aracı pervanesi üzerinde test edilmiştir. Tasarlanan bu açık kaynaklı şekil optimizasyonu döngüsünün oldukça etkili çalıştığı görülmüş ve sonucunda söz konusu pervanenin yararlılık katsayısı % 40 iyileştirilmiştir.

An Open-Source Aerodynamic Shape Optimization Application for an Unmanned Aerial Vehicle (UAV) Propeller

The Unmanned Aerial Vehicles (UAVs) have become more popular and functional for today’s needs in comparison to the conventional aircrafts for military, agriculture and private purposes. Generally, these vehicles are using propeller based propulsion systems. Thus, aerodynamic shape optimization is a vital process to improve their performance. Accordingly, in the present study, a Computational Fluid Dynamics (CFD) based open-source shape optimization framework (combined use of a CFD solver, Optimization solver, Free-Form Deformation (FFD) tool and Mesh Generator utility) is designed to optimize the shape of a generic UAV propeller. As a result, the open-source shape optimization framework here woks quite efficiently and the Figure of Merit (FM) of the propeller has been improved by around 40 %.
