基于Kriging方法的整流罩气动外形设计优化
Aerodynamic shape design optimization of fairing based on Kriging method
摘要
Abstract
The aerodynamic shape design optimization of fairing for launch vehicles based on Kriging approximate method was researched.In order to solve the computational complexity problem in aerodynamic shape design optimization of fairing,Kriging func-tion was introduced to establish the approximate model for predicting fairing aerodynamic parameter,the process for parameter esti-mation of Kriging function was deduced,and the specific implementation method was offered.The mathematic model for aerodynamic shape design optimization of fairing was established,and resolved with Kriging method.Simulation results show that convergence effi-ciency of proposed design method is more efficient,the average drag of optimal scheme is 22.2% less than the primary scheme,and all constraint conditions are well satisfied.All research finds can provide theoretical reference for aerodynamic shape design optimiza-tion of flight vehicles.关键词
