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