In response to the growing need of ground test facilities for flow conditions corresponding to re-entry of spacecraft in the planetary atmosphere, a Free Piston Type Hypersonic Expansion Tunnel is being established at Hypersonic Experimental Aerodynamic Laboratory at IIT Kanpur. Expansion tunnel is an impulse facility that uses enthalpy increment phenomenon of unsteady expansion. Free Piston Type Expansion Tunnel is 25.2 m long and has nozzle exit diameter of 0.2 m. Test time vary according to flow conditions but are order of 50 microseconds. Computational tools, high frequency static and pitot pressure measurements using PCB pressure transducer, Flow visualization using Schlieren technique, Temperature measurement and species determination using Emission Spectroscopy are utilized for characterization of flow conditions during test time. This facility is designed for stagnation enthalpies upto 40 MJ/Kg and flow velocity upto 8 km/s. The present work is in progress. Further details will be presented in conference.
