Supersonic Wind Tunnel

The supersonic wind tunnel at FCAAP is an intermittent blow down type facility. Tests can be carried out over a range of subsonic and supersonic Mach numbers with the current design's ease of nozzle replacement. The present test section is 101 mm wide, 76 mm high, and 381 mm long, with the side walls and floor made from optical quality glass for flow visualization and particle image velocimetry (PIV). The roof of the test section is removable for model mounting.


Operational/Test Capabilities
