6-m. Low-Speed Wind Tunnel at the National Aerospace Laboratory

A new low-speed wind tunnel has been in operation at the National Aerospace Laboratory since October, 1965. This tunnel is capable of providing wind velocities up to 60 m/s in a test section measuring 6.5m × 5.5m. Tunnel characteristics and the detail of the tunnel elements, as well as the design philosophy, are described in this note.
