8ft x 6ft Low Speed
The 8’x6’ Wind Tunnel at Cranfield University has a test section of 2.4 m x 1.8 m and a max speed of 50 m/s. It has a rolling road with boundary layer extraction, a 6-component overhead balance on 360deg rotating roof mounted turntable, an internal 6-component balance, a 6-component under-floor balance on rotating floor turntable (±25deg yaw) and four independent wheel drag load cells.
