Abstract:
1. A method of wind tunnel measurement of airfoil, comprising: providing a wind tunnel test apparatus, said wind tunnel test apparatus including: coupling both ends of an airfoil model under test with the two supporting members, respectively; generating a flow of a fluid in said wind tunnel flow path; and measuring a load applied to said airfoil model by using said two load measuring units, wherein a thin film member is stuck on each end of said airfoil model so that a part of said thin film member protrudes from said each end of said airfoil model along an outer circumference throughout an entire circumference, wherein said thin film member has a strength at which said thin film member enables to endure a pressure of said fluid, and is formed of a material which is elastically deformable, and wherein said thin film member is provided so that a gap between said each end of said airfoil model and one of said two walls facing to said each end of said airfoil model is blocked.
