OPEN JET SUBSONIC ACOUSTIC
TEST SECTION (OJATS)
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.
