A Multi-Point Approach to Airfoil Shape Optimization

摘要：

　　Airfoil design is essential for civil aircraft.A multi-point method is presented in this article to improve the aerodynamic performance of airfoil over a range of the flight envelope.This method combines computational fluid dynamics and numerical optimization.It comprises of three phases:1)Airfoil shape parameterization method to develop candidate shapes.2) Flow solver validation to calculate aerodynamic forces.3) Searching for the optimized airfoil shape using the genetic algorithm.The major limitation of single-point design is the poor off-design performance.By basing the objective on a combination of the drag at three design points,the resulting overall performance can be improved with respect to the single-point result.
