FSU's Polysonic wind tunnel has a 12" x 12" test section and a Mach number range of 0.2 to 5.0. This includes the transonic regime. Run times will vary between 60 and 100 seconds depending on flow conditions. The facility is equipped with a model support system with pitch control from - 10° to 15° and roll control from -180° to 180°.The facility includes a settling chamber with an acoustic silencer, 5 flow conditioning screens, and a honeycomb to minimize test section noise and turbulence levels. Supersonic Mach number is controlled using fix nozzle blocks. Currently the facility has a subsonic nozzle and individual nozzles for blocking Mach 2.0, 3.0, 4.0, and 5.0.

There are two test sections: sub/supersonic flow (24" long) and a slotted wall transonic test section (48" long). Both test sections have large optical access for a wide range of non-intrusive measurement techniques along with more conventional measurement techniques.
