Open Jet Subsonic Acoustic Test Section

This facility is configured as an open jet wind tunnel which is operated in a suction mode. In the current arrangement air   is delivered through a 3’x3’ square nozzle into a relatively large acoustically isolated test volume. Air speeds up to 60 MPH with less than 0.5% turbulent Intensity and low noise are currently available.






  • This acoustic section/chamber is 12’x12’ in cross section and 26’ in length.
  • For heavy loads the acoustically treated floor can be easily removed.
  • An overhead gantry extends the full width and length of the test, and holds a computer controlled traversing system.
  • Larger nozzles have been designed and can be also be accommodated.
