Closed-circuit wind tunnel SST

aeronauticalmodel support

THE SUPERSONIC WIND TUNNEL (SST) IN AMSTERDAM IS A FACILITY FOR RESEARCH AND DEVELOPMENT AS WELL AS INDUSTRIAL APPLICATIONS IN THE SUPERSONIC DOMAIN Type of wind tunnel The SST is a blow down tunnel fed by an air storage vessel containing 600 m3 of dry air at a maximum pressure of about 4,000 kPa. Main features TEST SECTION 1.2 m wide by max 1.2 m height The diffusor section, holding the model support, can be moved back creating excellent accessibility of the model. OPERATING RANGE Re0.1 √(S) < 14 x 106 Max running time is about 50 sec, depending on Mach number Sting support system with one remote controlled degree of freedom (typically AoA) at pre-set value of second axis (typically AoS) Supersonic model support (-6 - +15 deg) Optional alpha shifter (-6 - +35 deg) Pre-set value of bank angle for spacecraft, launchers and missiles AUXILIARY SYSTEMS Compressed air supply with a capacity of 8 kg/s continuously at 40 bar High quality optical Schlieren system for shock and expansion waves visualization Common electrical and mechanical interfaces with HST for easy change of facility Typical tests Configuration studies, database creation (supersonic aircrafts, fighters, spacecraft, launchers, missiles) (Basic) research tests
