Abstract:Low degree-of-freedom collaborative optimization was applied to solve multidisciplinary aerodynamic— 

slmctural design optimization ofalightaircraftwing.The sll*ucture subsystem andtheaerodynamics subsystem areparalle1. 

Aerodynamics performance was calculated wih Fltuent.Structure analysis was performed using MSC.Patran and Nastran. 

Based on Cati ̄Gambit and Fluent网络营销平台,an aerodynamics automatic analysis model Was proposed.In order to transfer 

aerodynamics load among diferent subsystems如何快速收录,a quartic response surface wih three coefticifents was developed to fit lift 

distribution.Basedonthe aerodynamics automaticanalysismodel andthequartic response surfacewihtthree coeficifntes,a 

construction method ofaerodynamics analysis surrogate models for high fidelity aerodynamics analysis Was proposed.The
