A test rig for the experimental evaluation of Surface Effect Ship SES lift fan models has been designed, fabricated, and integrated into one of the 8- by 10-foot subsonic wind tunnels at the David W. Taylor Naval Ship Research and Development Center DTNSRDC. Centrifugal and axial flow lift fan characteristics have been investigated under steady state as well as time-varying flow rate conditions. Fans of about 2 feet in diameter or less and up to 150 hp can be handled on the rig. Instrumentation includes transducers to measure pressure, power, and efficiency. Association with the rig is a digital data acquisition system capable of sampling data at rates of up to 12 KHZ. Author
