© by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved.A method of optimizing the geometry and position of high-lift system elements is presented. The design optimization method maximizes lift without increasing the drag of multi-element airfoils at take-off and landing configurations. It uses an incompressible Navier-Stokes flow solver, a chimera overlaid grid system, and a constrained numerical optimizer. A finite-difference method is used to obtain aerodynamic sensitivity derivatives. Optimum geometries and positions of high-lift devices are obtained at reasonable computational costs. Results demonstrate that numerical optimization can be an attractive design tool for the development of multi-element high-lift systems.

All rights reserved.During rocket/missile system design process, system design must be made in accordance with military standards, which have very strict rules. Product delivery dates usually are very rigid. Despite this, during conceptual design, requirements are often updated within the design process that requires the design to be updated frequently. It is essential to perform these steps as efficiently and quickly as possible. The pr...
Static aeroelastic analysis of supersonic nozzles and performance response
Duzel, U.; Eyi, Sinan (2014-01-01)
© 2014 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved.The effects of static aeroelasticity on the performance of supersonic nozzles are analyzed. A flow analysis was conducted to investigate five different configurations of two dimensional convergingdiverging nozzles. Computational results are validated with experimental data. Two of the configurations, which have the same throat area, throat radius, and convergence angle and total nozzle length are selected as the basel...
Noise prediction of a transonic cavity flow via shear-layer-adapted delayed detached-eddy simulation
Yalçın, Özgür; Özyörük, Yusuf (2018-01-01)
© 2018 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved.An open cavity flow contains a highly turbulent shear layer which separates from the upstream edge and impinges on the aft wall of the cavity, causing intense noise emission. In this study, a delayed detached-eddy simulation (DDES) with the use of "shear-layer-adapted" subgrid length scale, an enhancement of DDES available in literature, is conducted for such an open cavity flow problem. The results show that this len...
Analysis and adjoint design optimization of hypersonic blunt bodies
Piskin, Tugba; Eyi, Sinan (2014-01-01)

All rights reserved.The main purpose of this study is to analyze hypersonic flow field around the blunt bodies and to design of that bodies in order to obtain minimum pressure drag. Modeling of non-equilibrium must be done properly. In this study, non-equilibriums of thermal and chemical modes are considered. Translational and rotational energy modes are assumed that energy exchange between these modes is so fast. Vibrational and electro...
Efficiency improvement in sensitivity evaluation in aerodynamic shape optimization
Eyi, Sinan (1996-01-01)
© 1996 by the American Institute of Aeronautics and Astronautics, Inc. All rights resewed.The paper presents two methods that improve the accuracy and reduce the computational cost in evaluating finite-difference sensitivities for aerodynamic shape optimization. The first method is a modified finite-difference approach that improves the accuracy of sensitivities at a reduced cost using an improved iteration strategy. The second method finds the optimum perturbation size based on an asymptotic error formula....
