S1

The test facility ‘S1’ named ‘Vaigai’ is the first in the series of Shock tunnel test facilities at IITK. The facility is multifaceted; can be operated as shock tube/ Ludwieg tube/ shock tunnel, both in reflected as well as straight through mode. The test facility is 10 m long with 2m Driver, 6 m Driven and 2 m long dump tank assembly with test section dimension of 300X300X450 mm. The facility generates Mach 4 and Mach 6 flow based on the nozzle throat insert, in the enthalpy range 0.3 – 1.8 MJ/kg, Reynolds number range 0.5 – 20 million/m, depending on the mode of operation and fill condition.




S2

The test facility ‘S2’ named ‘JigarThanda’ is second in the series of Shock tunnel test facilities at IITK. The facility is a Free Piston driven type; can be operated as reflected shock tunnel or expansion tunnel. The test facility is designed to generate flow enthalpies ranging from 3 to 40 MJ/kg, simulating flight velocities ranging from 2.5 to 12 km/s depending on fill conditions.

The facility is in fabrication stage and shall be commissioned by the end of 2021.
