Viscous single and multicomponent airfoil design with genetic algorithms
نویسندگان
چکیده
An optimization procedure aimed at the design of multicomponent airfoils for high-lift applications is described. The procedure is based on a multiobjective genetic algorithm; two #ow solvers have been coupled with the genetic algorithm: a viscous}inviscid interaction method, based on an Euler #ow solver and an integral boundary layer routine, and a method based on a full potential #ow solver. The "rst model is used for high-lift con"gurations, whereas the second is used to optimize transonic performances for cruise con"gurations. The applications described include both single and multiobjective design of a high-lift multicomponent airfoil, and a multipoint design where the transonic and high-lift requirements are taken into account simultaneously. 2001 Elsevier Science B.V.

In this paper, optimal airfoil shapes are found through manipulation of the velocity distribution by a genetic algorithm. The airfoil geometries are generated by an inverse method from velocity distribution parameters, and a viscous-flow analysis code is used to determine proper fitness values for candidate airfoils based on preset performance criteria.
