High-fidelity aerodynamic dataset generation is one of the most significant components of the aircraft flight simulation, and, it is a time consuming and costly process. Data fusion techniques suggest that, instead of using high fidelity data for entire aerodynamic dataset, an incorporating combination of high-fidelity and low-fidelity data is a more cost-effective one. The objective of data fusion is to obtain high-fidelity dataset accuracy by combining less amount of high-fidelity dataset and more amount of low-fidelity dataset. In this paper, two different data fusion approaches, namely modified Variable-Complexity Modelling and co-Kriging, are applied to F-16 fighter aircraft. Wind tunnel test data is utilized as the high-fidelity dataset while data obtained by a semi-empirical approach (Digital Datcom) is used as the low-fidelity dataset.

Multidisciplinary and multiobjective design optimization of an unmanned combat aerial vehicle (UCAV)
Çavuş, Nesrin; Tekinalp, Ozan; Department of Aerospace Engineering (2009)
The Multiple Cooling Multi-Objective Simulated Annealing Algorithm is used for the conceptual design optimization of a supersonic Unmanned Combat Aerial Vehicle (UCAV). Single and multiobjective optimization problems are addressed while limiting performance requirements between desired bounds to obtain viable aircraft configurations. A conceptual aircraft design code was prepared for planned but flexible combat missions. The results demonstrate that the optimization technique employed is an effective tool f...
Numerical investigations of lateral jets for missile aerodynamics
Ağsarlıoğlu, Ekin; Albayrak, Kahraman; Department of Mechanical Engineering (2011)
In this thesis, effects of sonic lateral jets on aerodynamics of missiles and missilelike geometries are investigated numerically by commercial Computational Fluid Dynamics (CFD) software FLUENT. The study consists of two parts. In the first part, two generic missile-like geometries with lateral jets, of which experimental data are available in literature, are analyzed by the software for validation studies. As the result of this study, experimental data and CFD results are in good agreement with each other...
Nonlinear modeling and flight control system design of an unmanned aerial vehicle
Karakaş, Deniz; Balkan, Raif Tuna; Department of Mechanical Engineering (2007)
The nonlinear simulation model of an unmanned aerial vehicle (UAV) in MATLAB®/Simulink® environment is developed by taking into consideration all the possible major system components such as actuators, gravity, engine, atmosphere, wind-turbulence models, as well as the aerodynamics components in the 6 DOF equations of motion. Trim and linearization of the developed nonlinear model are accomplished and various related analyses are carried out. The model is validated by comparing with a similar UAV data in te...
Comparison of Various Spring Analogy Mesh Deformation Techniques in 2 D Airfoil Design Optimization
Yang, Yosheph; Özgen, Serkan (null, 2015-06-29)
During the last few decades, CFD (Computational Fluid Dynamics) has developed greatly and has become a more reliable tool for the conceptual phase of aircraft design. This tool is generally combined with an optimization algorithm. In the optimization phase, the need for regenerating the computational mesh might become cumbersome, especially when the number of design parameters is high. For this reason, several mesh generation and deformation techniques have been developed in the past decades. One of the mos...
Dynamic modelling and control of a gimballed airborne antenna platform with mass unbalance and friction
Şeref, Tuğçe; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2018)
Inertial stabilized gimballed systems are widely-used in many applications to achieve a high precision positioning. Airborne antennas pointing target as a part of the satellite communication may be examples of such systems. This thesis presents the dynamic modelling and control of a two axes gimballed airborne antenna platform. First, reference frames and the transformation matrices are defined to build up the motion of the antenna and kinematic equations of each gimbal are derived. Next, the dynamic equati...
