Aerodynamic parameter estimation of a missile
Aksu, Arda; Kutay, Ali Türker; Department of Aerospace Engineering (2013)
Aerodynamic characteristics of missiles depend strongly on wind angles, that is, angle of attack and sideslip angle. However it is impractical to measure these angles during missile testing. Therefore, without direct information of the wind angles, it becomes a difficult problem to be able to accurately estimate the missile aerodynamic parameters from flight tests. This thesis addresses this problem and suggests an approach to estimate missile aerodynamic parameters successfully without wind angles measurem...
Aerodynamic modelling and optimization of morphing wings
Körpe, Durmuş Sinan; Özgen, Serkan; Department of Aerospace Engineering (2014)
This thesis deals with aerodynamic optimization of morphing wings under performance and geometric constraints. In order to perform the optimization process, flow solvers computing aerodynamic lift and drag were developed as a function evaluator. A gradient based optimization method was used in order to develop the optimization algorithm. Three dimensional panel method solver was developed in order to obtain lift, pressure drag and induced drag values for a finite wing. Obtained results were compared with di...
Aerodynamic Design Analysis Of Missiles With Strake Configurations At Supersonic Mach Numbers
Usta, Engin; Kıvanç, Arslan; Tuncer, İsmail Hakkı (2015-09-10)
In this study a neural network based method is developed for the prediction of separation characteristics of external store weapons carried under aircraft wings. The method is based on an artificial neural network trained by high fidelity unsteady flow solutions. The unsteady flow solutions as the store separates from the carriage and the resulting six degrees of freedom motion of the store are computed conditions by a commercial flow solver for various flight conditions. The trajectory of the store and the...
Aerodynamic Modelling and Analysis of a Novel Mechanism for Chord and Camber Morphing Wing
Şahin, Harun Levent; Çaklr, Bora Orçun; Yaman, Yavuz (2018-06-22)
This paper presents the aerodynamic modelling and analysis of surfaces created by a novel deployable mechanism, which is composed of a four-bar linkage and a scissor-structural mechanism (SSM) which contains several scissor-like elements (SLEs). With the help of that mechanism, which is located inside the trailing portion of wing section, continuous adjustment of the airfoil is possible. In order to highlight the advantageous aerodynamic characteristics of newly created airfoil geometries via proposed SSM, ...
Aerodynamic investigation of a model scale helicopter rotor in ground effect
Şahbaz, Mehmet; Kurtuluş, Dilek Funda; Sezer Uzol, Nilay; Department of Aerospace Engineering (2017)
In this thesis, ground effect issue which is a vital topic for helicopter industry is investigated with model scale.For this purpose, a test setup with model helicopter rotor is established. With setup, ground effect is investigated with inclined ground and ground without inclination. Thrust and torque values are obtained for different rotation speeds with constant collective pitch. Comparison with literature is done and reliability of the test setup is proven. Inclined Ground Effect and Ground Effect with ...
