A New Optimization Model for Rotary-Wing Air Vehicle Propeller Design

Abstract

IIn this study, the propeller characteristics of the aircraft have been optimized in terms of stabilization and manoeuvrability and it has been aimed to find the ideal propeller dimensions for the aircraft. A mathematical modelling has been developed for optimization and four different objectives are simultaneously optimized in the model. The results have been compared with simulation, analysis and real results. Gams and MATLAB programs have been used for developed mathematical model and simulation algorithm, respectively, and ANSYS program has been also used for CFD analysis. It has been observed that CFD analysis and mathematical model results are parallel to each other. As a result of the analysis, thanks to the developed model, a 6.47% improvement has been achieved in efficiency compared to the existing propeller system. In addition, an improvement of 3.93 times in “thrust” and 3.86 times in “total lift force” has been provided. Finally, it has been reported that the total drag force has been successfully minimized.

Döner Kanatlı Hava Aracı Pervanesi Tasarımı için Yeni Bir Optimizasyon Modeli

Abstract

Bu çalışmada, uçağın pervane karakteristikleri stabilizasyon ve manevra kabiliyeti açısından optimize edilmiş ve uçak için ideal pervane boyutlarının bulunması amaçlanmıştır. Optimizasyon için yeni bir matematiksel model geliştirilmiş ve modelde dört farklı hedef aynı anda optimize edilmiştir. Elde edilen sonuçlar simülasyon, analiz ve gerçek sonuçlar ile karşılaştırılmıştır. Geliştirilen matematiksel model ve simülasyon algoritması için sırasıyla Gams ve MATLAB programı kullanılmış, CFD analizi için de ANSYS programı kullanılmıştır. CFD analizi ve matematiksel model sonuçlarının birbirine paralel olduğu gözlemlenmiştir. Analiz sonucunda, geliştirilen model sayesinde mevcut pervane sistemine göre verimlilikte %6,47'lik bir iyileşme sağlanmıştır. Ayrıca “itme kuvvetinde” 3,93 kat, “toplam kaldırma kuvvetinde” ise 3,86 kat iyileşme sağlanmıştır. Son olarak toplam sürükleme kuvvetinin başarılı bir şekilde minimize edildiği tespit edilmiştir.
