基于摄影测量前方交会的翼伞风洞测试方法
Wind Tunnel Test Method of Parafoils Based on Photogrammetric Forward Intersection
摘要
Abstract
The test method of flexible parafoil in wind tunnel test is explored.The photogrammetric forward in-tersection method is used to synchronously photograph multiple feature points on the wing surface,obtain the 3D coordinates of the feature points,and calculate the actual angle of attack of the parafoil under different working conditions.The variation of aerodynamic moment parameters of parafoil at different angles of attack is tested,and the relationship between angle of attack and parafoil lift resistance is analyzed,which provides quantitative basis for optimizing parafoil design.This test method solves the problem that it is difficult to accu-rately quantify the dynamic deformation of flexible parafoil in the traditional wind tunnel test,and provides key technical support for the aerodynamic performance optimization and engineering application of parafoil.关键词
