Test Section: 0.6m X 0.6m
Operation: Intermittent blow down
Test duration:60 seconds for 0.6m tunnel
Mach number range : 0.2 to 4.0 
Off-line flexible nozzle for supersonic
On-line flexible nozzle for supersonic 
Mach number tests in 0.6m tunnel
Model incidence	: -15  degrees to +27 degrees continuous  and step modes
Model roll: 0 degrees to 360 degrees   
Stagnation pressure: 1.5 to 8.0 bar
Reynolds number: 8 x 106 to 60 x 106 per meter

The special feature of the facility avoids start-stop loads on the model, wherein the tunnel can be started at low supersonic Mach number 1.4 and the nozzle contour changed online to achieve higher supersonic Mach numbers up to 10 sec using VMFN. The tunnel has logged more than 5000 blow downs.
The facility is backed by state of the art design tools
Solid and surface modeling capability (CATIA/Solid Works/Auto CAD).
C.A.E. solutions(COSMOS works/ HyperWorks).
NC programming (Solid CAM)
