The NASA Lewis 9- by Foot Low-Speed Wind Tunnel was designed for determining the aerodynamic performance of aircraft propulsion systems and components at both takeoff and approach conditions. Since community noise is an impor-tant consideration during takeoff and approach, the wind tunnel test section was lined with acoustic material which.

Dahl, M. D., and Woodward, R. P.,“Comparison Between Design and Installed Acoustic Characteristics of the NASA Lewis 9- by Foot Low-Speed Wind Tunnel Acoustic Treatment,” NASA Technical Paper Cited by: The test section of the NASA Lewis 9- by Foot Low Speed Wind Tunnel was acoustically treated to allow the measurement of acoustic sources located within the tunnel test section under simulated.

The mission at Lewis was the testing of aircraft power plants. An engine exhaust catcher had sufficed in the earlier altitude wind tunnel, but the advent of big turbojets and ramjets spewing huge amounts of hot gases made this device impracticable for full-scale engine testing.
