B4C/SiC/Al2O3 particle reinforced aluminum sandwich foam and ramor 500 armor steel to be combined and investigation of the ballistic performance
Karakoç, Halil; Ulutaş, Aytekin; Çinici, Hanifi (Gazi Univ, 2020)In this study, the ballistic performances of particle-free Al sandwich foams (ASK) containing SiC, B4C and Al2O3 prepared by powder metallurgy were investigated. For this purpose, the mixture powders were subjected to ... -
Confidence interval prediction of ANN estimated LPT parameters
Yıldırım, Mustagime Tülin; Kurt, Bülent (Emerald Group Publishing Ltd, 2019)Purpose With the condition monitoring system on airplanes, failures can be predicted before they occur. Performance deterioration of aircraft engines is monitored by parameters such as fuel flow, exhaust gas temperature, ... -
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 ... -
The effect of employee motivation on performance and work commitment
Yıldız, Derya; Şen, Gülaçtı (Türk Kooperatifçilik Kurumu, 2024)This research was conducted in Esenyurt District, the most densely populated district of Istanbul in 2023. A survey was conducted with the voluntary participation of 344 public employees working in public institutions ... -
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 ... -
Model for managing divert risk caused by low visibility in airline operations management
Akbaba, Ali (Sage Publications Inc, 2023)In airline operations management, one can state that because of meteorological conditions, flights may have to land at an appropriate alternate airport instead of the destination. One of these meteorological conditions can ... -
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 ... -
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 ...
