Abstract

Inverse design was formulated as a variational problem in which a control system minimizes the differences between the actual and the desired velocity over an airfoil surface by making successive changes in the airfoil shape. First, the initial and desired airfoil velocities, Mach number and angle of attack are specified. Then, a flow solver computes the actual velocity and pressure distribution around the airfoil. A cost functional, which represents the deviation of the actual velocity, is computed. If the cost functional has reached a minimum, the process ends. Otherwise, a variation is made in the airfoil shape to reduce the cost functional. The inverse design enhances the efficiency of the aerodynamic design process by several orders of magnitude.
