Air-breathing scramjet engines promise very high speeds at special flight trajectories, which boost research on this field. Air intake is one of the most critical components during the design process of these engines. Not only it leads the overall performance of the scramjet cycle, but also geometry of the intake affects the survivability of the vehicle at hypersonic flight conditions. Although there are many types of intakes, the design of 2-D intake with ramps is investigated in present thesis. After validating CFD methodology with experimental data, results of the inviscid design tool are compared with viscous CFD results for design point and off-design points. Fluent is used as commercial CFD solver. It is observed that such a tool can be used for preliminary design process with acceptable differences before conducting intense viscous CFD analysis.

Development of a design method for subsonic intakes with improved aerodynamic performance and reduced radar signature Ünlü, Tezcan; Eyi, Sinan; Department of Aerospace Engineering (2021-9-2) In this thesis, a design method for a subsonic intake with high aerodynamic performance and reduced radar signature is developed. Intakes are key components of aircrafts’ propulsion systems that create open ended cavities resulting in increased radar signature. To achieve reduced radar signature characteristics, a parameterized double curved intake is proposed. Due to the nature of this multi-objective and multi-disciplinary engineering problem, surrogate based analysis and optimization approach is taken to...
Validation of MISES 2 D Boundary Layer Code for High Pressure Turbine Aerodynamic Design ANDREW, PHILIP; Kahveci, Harika Senem (2007-01-01) Avoiding aerodynamic separation and excessive shock losses in gas turbine turbomachinery components can reduce fuel usage, and thus reduce operating cost. In order to achieve this, blading designs should be made robust to a wide range of operating conditions. Consequently, a design tool is needed which can be executed quickly for each of many operating conditions, and on each of several design sections which will accurately capture loss, turning and loading. This paper presents the validation of a boundary ...
Design optimization of variable frequency driven three-phase induction motors Ertan, B; Leblebicioğlu, Mehmet Kemal; Simsir, B; Hamarat, S; Cekic, A; Pirgaip, M (1998-01-01) An approach to optimize the design of three-phase induction motors for a wide speed range drive is considered. Two operating points in the speed range are taken into consideration. The problem is handled as a constrained optimization problem. An accurate model for the motor in terms of its dimensions has been developed which predicts the motor performance based on about 60 parameters of motor geometry.
Analysis of a UAV that can Hover and Fly Level Cakici, Ferit; Leblebicioğlu, Mehmet Kemal (EDP Sciences; 2016-03-14) In this study, an unmanned aerial vehicle (UAV) with level flight, vertical take-off and landing (VTOL) and mode-changing capability is analysed. The platform design combines both multirotor and fixed-wing (FW) conventional airplane structures and control surfaces; therefore, named as VTOL-FW. The aircraft is modelled using aerodynamical principles and linear models are constructed utilizing small perturbation theory for trim conditions. The proposed method of control includes implementation of multirotor a...
Experimental Investigation of Aerodynamics of Flapping-Wing Micro-Air-Vehicle by Force and Flow-Field Measurements Deng, Shuanghou; Perçin, Mustafa; van Oudheusden, Bas (2016-02-01) This study explores the aerodynamic characteristics of a flapping-wing micro aerial vehicle (MAV) in hovering configuration by means of force and flowfield measurements. The effects of flapping frequency and wing geometry on force generation were examined using a miniature six-component force sensor. Additional high-speed imaging allowed identification of the notable different deformation characteristics of the flexible wings under vacuum condition in comparison to their behavior in air, illustrating the re...
