Walter H. Beech Wind Tunnel
WSU Wind Tunnels
The Beech Wind Tunnel is an atmospheric, return type, closed-throat, subsonic wind tunnel with a test section seven feet high, 10 feet wide and 12 foot long. Air speeds in the test section can reach in excess of 200 mph.
A dual circuit, closed loop, liquid-filled heat exchanger is used to limit temperature rise in the tunnel and permits full speed operation all day long, seven days a week.Flow conditioning elements including a precise honeycomb structure and spring-tensioned screen installed in the stilling chamber straighten and smooth out the airflow in the test section.The test section has a large amount of glass-paned optical access for virtually all flow visualization techniques and positions. It can be disassembled for ease of model installation. The test section has been designed for a future capability of measuring wall pressure signatures.
The six-component, truncated prism, pyramidal under-floor external balance is accurate, precise and has a large measurement capability for forces and moments. It can also quickly position models in both pitch and yaw axis over a large motion range.
