A lattice of vanes positioned upwind to the measuring station of an air tunnel consists of flat airfoils with chord length c. The maximum wind velocity expected is 22.7m/s. The critical Reynolds number for turbulent transition is Rex,cr = Uoxc V = 5.105 2 v = 1.5.10-5 m² S Calculate the maximum chord length c so that the flow will not exceed the critical Re number. Present your answer in meters (m).

Question
A lattice of vanes positioned upwind to the measuring station of an air tunnel consists of flat airfoils with chord length c. The maximum wind velocity expected is 22.7m/s. The critical Reynolds number for turbulent transition is Rex,cr = Uoxc V V = 1.5.10 = 5.105 2 5 m² S Calculate the maximum chord length c so that the flow will not exceed the critical Re number. Present your answer in meters (m).
