Trisonic Wind Tunnel


The facility blow-down type, pressurized.  The main functionality is the measurement of forces and moments with six component strain gage balances. Pressure instrumentation is available for the models, as well as a Schlieren vizualisation system. Mach number is in the range from 0.3 to 3.5. Maximum reynolds number is 100 Million for a reference length of 1m.
