- Reynolds capability (per meter); max. 100x106 (3D) , max. 150x06 (2D)
- Force and moment measurements are made using sting mounted internal strain gauge balances.
- Pressure measurements are made using pressure transducers and pressure scanning devices
- Operation is fully automatic by means of high speed Data Acquisition and Tunnel Control systems
- A 30" diameter Schlieren visualization system is in operation
- A Dorsal Visualisation system can be installed above the transonic test section
- A CTS (Captive Trajectory Simulation) system with three degrees of freedom is being developped
- A High Pressure air supply is available for jets and engine simulations.
