The effects of sensitivity analysis on the performance of aerodynamic design were evaluated. Sensitivities were obtained by both analytical and finite-difference approach. A sensitivity code was developed to analytically obtain sensitivities using the material derivative concept of continuum mechanics. Several design optimizations were performed to evaluate the merits of the analytical approach in comparison with the finite-difference approach. The results show that the analytical approach provides accurate sensitivities consistently, improves the convergence of the design cycle, and hence reduces the design cost. © 2000 The Amarican Institute of Aeronautics and Astronautics Inc.

Aerodynamic shape optimization of a wing using 3d flow solutions with su2 and response surface methodology Yıldırım, Berkay Yasin; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2021-4) In this study, the aerodynamic shape optimization of a wing is performed by using 3D flow solutions together with response surface methodology. The purpose of this study is to optimize the aerodynamic shape of a wing to achieve the lowest possible drag coefficient while ensuring desired maneuvering capability and lateral stability. Aerodynamic shape optimization is performed for a wing of a turboprop trainer aircraft. Optimization objective and constraints are determined according to mission requirements an...
Effects of sensitivity derivatives on aerodynamic design optimization Eyi, Sinan (Informa UK Limited, 2007-10-01) The effects of sensitivity derivatives on the performance of aerodynamic design optimization were evaluated. Sensitivity derivatives were obtained by both analytical and finite-difference approaches. A sensitivity code was developed to analytically obtain sensitivity derivatives for the two-dimensional Euler equations using the material derivative concept of continuum mechanics. Several inverse design optimizations were performed to evaluate the merits of the analytical approach in comparison with the finit...
Aerodynamic design optimization of three dimensional rocket nozzles using adjoint method Eyi, Sinan (null; 2013-09-13) A design optimization method based on three dimensional Euler equations is developed. A finite volume method is implemented to discretize the Euler equations. Newton's method is used to solve the discretized form of Euler equations. Newton's method requires the calculation of the Jacobian matrix which is the derivative of the residual vector with respect to the flux vector. Different upwind methods are used in the calculation of flux vectors. Numerical and analytical methods are utilized in the evaluation o...
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...
