An Efficient Aerodynamic Shape Optimization Framework for Robust Design of Airfoils Using Surrogate Models
This paper deals with developing an efficient Robust Design Optimization (RDO) framework. The goal is to obtain an aerodynamic shape that is less sensitive to small random geometry perturbations and to uncertain operational conditions. The initial shape is the RAE2822 airfoil which is parameterized with 10 design variables. The robust design formulation used is based on an expectation measure. ...
متن کاملProbabilistic Aerothermal Design of Compressor Airfoils
Despite the generally accepted notion that geometric variability is undesirable in turbomachinery airfoils, little is known in detail about its impact on aerothermal compressor performance. In this work, statistical and probabilistic techniques were used to assess the impact of geometric and operating condition uncertainty on axial compressor performance. High-fidelity models of geometric varia...
متن کاملThe Effects of Shape Parameterization on the Efficiency of Evolutionary Design Optimization for Viscous Transonic Airfoils
The effect of airfoil shape parameterization on optimum design and its influence on the convergence of the evolutionary optimization process is presented. Three popular airfoil parametric methods including PARSEC, Sobieczky and B-Spline (Bezier curve) are studied and their efficiency and results are compared with those of a new method. The new method takes into consideration the characteristics...
متن کاملMultipoint Inverse Design of an Infinite Cascade of Airfoils
Tbis paper describes a method for the design of an infinite cascade in incompressible Dow. The method is bued on conformaJ mapping and does aJlow for multipoint design. The cascade blade to be determined is divided into a desired number of segments. Over each segment. the velocity distribution is prescribed together with an inlet or outlet Dow angle at which this velocity distribution is to be ...
متن کاملUnsteady Adjoint Approach for Design Optimization of Flapping Airfoils
This paper describes the work for optimizing the propulsive efficiency of flapping airfoils, i.e., improving the thrust under constraining aerodynamic work during the flapping flights by changing their shape and trajectory of motion with the unsteady discrete adjoint approach. For unsteady problems, it is essential to properly resolving time scales of motion under consideration and it must be c...
