This facility assesses conventional performance for low-speed tests of powered and unpowered models of various fixed- and rotary-wing civil and military aircraft over a wide range of takeoff, landing, cruise and high angle-of-attack conditions. The tunnel can be easily reconfigured for acoustic, tethered free-flight and forced-oscillation (dynamic stability) testing, as well as for motor sports studies. Investigators can chose from either closed (walls, ceiling and floor) or open (floor-only) test-section arrangements.
