| It is a semi-circuit, intermittent transonic and supersonic wind tunnel. The tunnel is equipped with a high angle of attack test mechanism, captive trajectory system for external stores, high speed jet test setup, fluctuating pressure measurement system, digital measurement system for inlet dynamic distortion, dynamic derivative test setup and test setup for flutter/buffet onset measurements.
