临近空间太阳能飞行器着陆状态阵风响应
Gust Loads in the Landing State of Solar-Powered Aircraft in Near Space
摘要
Abstract
A numerical simulation study on the gust response problem of near-space solar-powered aircraft during the landing phase is conducted.Considering the characteristics of such aircraft of lightweight,high flexibility,and low land-ing speed,CFD/CSD loosely coupled analysis method is employed,and gust loads are introduced using the grid velocity method.Based on the 1-cos gust model,the changes of wingtip displacement,torsional angle,overall bending moment at the wing root,and lift coefficient when the aircraft encounters two-dimensional gust load during landing are investigated.The two-dimensional gust response results are compared with the one-dimensional gust response results.The effects of the two-dimensional gusts along the wingspan variation during landing on aircraft structure and aerodynamic performance is obtained.The research results are expected to provide reference and assistance for the development of similar aircraft.关键词
