An Aerostructural 3D wing optimization using parallel genetic algorithms
Arpacı, Anıl; Üçoluk, Göktürk; Department of Computer Engineering (2019)
As a multi-disciplinary optimization problem, aerostructural shape optimization of airplane wings requires both aerodynamic and structural analysis to meet an objective defined as the sum of parameters like drag to lift ratio and wing weight, subjected to penalty of structural yield stress and geometrical sizing constraints to get aerodynamically efficient and lightweight 3D wings. In our study, genetic algorithms are utilized for optimization of 3D wing with its internal structural components. In order to ...
Full-Wave Electromagnetic Optimisation of Corrugated Metallic Reectors Using a Multigrid Approach
KARAOVA, Gokhan; ALTINOKLU, Askin; Ergül, Özgür Salih (2018-01-19)
A multigrid optimisation strategy is introduced to design passive metallic reflectors with corrugated shapes. The strategy is based on using genetic algorithms at multiple grids and shaping the metal sheets, starting from coarse details to fine tunings. This corresponds to a systematic expansion of the related optimisation space, which is explored more efficiently in comparison to a brute-force optimisation without using grid. By employing the multilevel fast multipole algorithm to analyse the electromagnet...
A Functional design methodology with genetic algorithm optimization to a door actuation mechanism
Akman, Hasan; Turgut, Ali Emre; Department of Mechanical Engineering (2019)
In this thesis, the preliminary design of an in-flight refueling door actuation mechanism is designed. A novel design methodology is introduced to create and evaluate different mechanism design alternatives systematically. The design is divided into two sub-problems. For each sub-problem, different conceptual design alternatives and evaluation criteria are created considering the design requirements. Suitable concepts are systematically selected among the alternatives based on the evaluation criteria. Then,...
Design and analysis of a hybrid trailing edge control surface of a fully morphing unmanned aerial vehicle wing
Tunçöz, İlhan Ozan; Yaman, Yavuz; Department of Aerospace Engineering (2015)
In this thesis, the design and analysis of a hybrid trailing edge control surface of a fully morphing unmanned aerial vehicle wing having the ability to perform both camber and decamber morphings were conducted. The design of the control surface was done by CATIA V5-6R2012 package program. Two distinct designs, so-called open cell and closed cell designs were initially analyzed via Finite Element Method by using the commercial software ANSYS Workbench v14.0 in in-vacuo condition. Several trade-off studies i...

The aerodynamic design of an aircraft's forebody geometry has a significant impact on its performance and stability. Although most studies on aircraft performance have focused on optimizing wing-like structures, the contribution of an effective forebody design to aircraft performance could be as significant as that of wing-like structures. A well-designed forebody can reduce the wave drag and improve the directional characteristics at high angles of attack. The forebody optimization of a jet trainer ai...
