The lab provides facilities in the areas of High Speed Jet Mixing and Acoustics, Supersonic Combustion and so on. In addition to catering to the needs of undergraduate and post-graduate laboratory course needs, it caters to the research requirements of a large number of Doctoral (PhD) and Master (MTech) students. Currently 7 doctoral students are doing their research in the lab. The lab is equipped with an indigenously built Jet Acoustic Chamber, which is unique in India.

The lab also houses an intermittent, blowdown type supersonic wind tunnel. The tunnel is equipped with a dedicated computer system for tunnel control and data acquisition. This facility has already made substantial contribution in establishing new testing techniques and basic research in the area of transonic/supersonic flows.
