Aerodynamic performance comparison of airfoils in flying wing UAV
Durmuş, Seyhun (2023)The aim of the study is to investigate how the choice of airfoil affects the aerodynamic characteristics of a flying wing UAV. For this purpose, comparative analyzes were performed for four different airfoils: MH60, TL54, ... -
Deciphering the relationship between the mass, size and engine properties of Boeing and Airbus aircraft
Durmuş, Seyhun (2022)In the study, it is aimed to analyze the mass, size, and engine characteristics of different Boeing and Airbus aircraft models, which are the duopoly in air transportation market, and to decipher the correlations between ... -
Designing and producing a bird-inspired unmanned sailplane
Keskin, Göksel; Durmuş, Seyhun; Karakaya, Muharrem; Kuşhan, Melih Cemal (Emerald Group Publishing Ltd., 2021)Purpose – Increasing endurance was a very appropriate subject for the biomimetic approach. The study aims to design and manufacture a longlasting mini unmanned aerial vehicle (UAV) using active gliding and soaring. Desi ... -
Investigation of wing forms through mass and wing area chart
Durmuş, Seyhun (2022)The wing loading parameter depending on the wing area and weight and the aspect ratio parameter, which is the wing shape factor, are the main parameters that determine the fixed-wing flight mechanics. In this study, the ... -
Is there any aerodynamic obstacle to gliding in great bustard?
Keskin, Göksel; Durmuş, Seyhun; Karakaya, Muharrem; Karataş, Mehmet Mahir (Inst Zoology, 2021)Gliding and soaring are important flight styles, which reduce the energy consumption of birds. Most of the migratory birds and raptors take advantage of these flight styles in order to stay in the air much longer. However, ... -
A key design parameter proposal for aerodynamically efficient subsonic blended wing body
Durmuş, Seyhun (Emerald Group Publishing Ltd., 2021)Purpose Blended wing body (BWB) is a very advantageous design in terms of low fuel consumption, low emission and low noise levels. Because of these advantages, the BWB is a candidate to become the commercial passenger ... -
Numerical investigation of effusion cooling in gas turbine combustor liner
Durmuş, Seyhun (Vedat Veli ÇAY, 2021)In this study, a numerical analysis was performed to find the aerothermal characteristics of the effusion cooled gas turbine combustor liner. The analyzed geometric model is a scale model of an actual combustor liner. The ... -
Relationship between wingspan and fuselage length in aircraft according to engine types
Durmuş, Seyhun (2023)The study aims to explain the size relationship between wingspan and fuselage length, which are the two basic design parameters that a designer is most curious about. Within the scope of the study, the relationship between ... -
Soaring strategy investigation of cinereous vulture (Aegypius monachus) by sailplane
Durmuş, Seyhun; Keskin, Göksel (Indian Counc Agricultural Res, 2020)Soaring has great importance to large and heavy terrestrial birds because they can gain altitude without using power in this way. The cinereous vultures were near threatened species in the world, so it was hard to observe ... -
Statistical analysis of airfoil usage in aircraft
Durmuş, Seyhun (Vedat Veli Çay, 2024)The study aims to answer how frequently airfoils are used in fixed and rotary wing aerial vehicles produced both individually and based on airfoil families. Frequency distribution analysis of airfoil utilization in fixed-wing ... -
Theoretical model proposal on direct calculation of wetted area and maximum lift-to-drag ratio
Durmuş, Seyhun (Emerald Group Publishing Ltd., 2021)Purpose As measuring flight performance by experimental methods requires a lot of effort and cost, theoretical models can bring new perspectives to aircraft design. This paper aims to propose a model on the direct calculation ...
