Investigation of the adjoint method in aerodynamic optimization using various shape parameterization techniques

摘要: This paper studies the effect of design variables vector on automatic aerodynamic shape optimization in adjoint method. Three techniques are studied: surface points, relations NACA 4-digit airfoil series and Hicks-Henne "Bump" Functions. First, this presents complete formulation optimal problem for Euler equations. Second, implementation these representation methods explored. Finally, results presented inverse drag minimization problems. The show that mechanism, value trend reduction during strongly affected by type vector.
