LSWT|SD is a continuous circuit facility with a test section 8 feet high, 12 feet wide and 15 feet long. It operates at Mach numbers up to 0.35. Aerodynamic, propulsion, loads and aeroelasticity (flutter) testing can be accommodated. The tunnel shell consists of reinforced concrete with a smooth painted interior finish which provides low-turbulence, clean airflow. A honeycomb section located upstream of the contraction ensures uniform velocity distribution throughout the test section.
