Popis: |
A method for airfoil and slotted ap design optimization using hybrid optimization approach and multidelity aerodynamic analysis was developed. The procedure is based on global optimization using medium delity aerodynamic solvers to localize the optimum design search region and local gradient-based optimization using combination of medium delity solver, high delity CFD solver and surrogate models. The geometry parameterization of airfoil is performed using CST method. Flap parameterization method was developed using Piecewise Bezier curves to capture speci c geometry of slotted ap. Designed airfoil and ap show good aerodynamic performance for given ight conditions of VLA category aircraft: low cruise drag and high lift at landing speed using slotted ap and without it. The aerodynamic analysis method shows good agreement with experimental results due to combination of strong points of each solver. |
