摘要

摘要: 为了提高大型飞机机翼的气动性能,发展了基于Bezier-Bernstein曲线的机翼气动布局参数化技术和网格变形技术,以及基于Navier-Stokes方程的流场解算器、伴随算子解算器和二次规划寻优算法,形成了气动布局优化软件.通过改变约束条件、设计参数范围和初始点,对机翼进行了一系列的极多参数和多约束的气动布局精细优化设计,得到了良好的优化结果,优化结果表明该优化方法是高效和可靠的.

Abstract: The optimization software was developed to improve the performance of the wing of large airplane.This software include the three main techniques:the aerodynamic configuration parameterization and grid update technique based on Bezier-Bernstein curve parameterization method;the flow solver and adjoint solver based on three-dimensional (3-D) Reynolds averaged Navier-Stokes equations;the optimization method based on sequential quadratic programming algorithm.This paper did series optimization for a wing with many design variables and different constraints and get some excellent results,The analysis to the result shows the optimization method is reliable and efficient.
