| Other Test Information | Over the years several augmentations have been incorporated to meet the wide range of needs of aerospace programmes in the country. The tunnel has logged more than 42000 blow downs. Tunnel Control System: The Integrated Tunnel Control system (ITCS) is based on a standard PC with real time hardware built into it. The control software is designed to be menu driven, operator independent, interactive and fully message oriented and is built with necessary safety and emergency routines. Data Acquisition System: NI based 24 channel DAS 48 channel high-speed DAS for unsteady pressure data up to 40 kHz. 24 channel high-speed wireless system for simultaneously acquisition of unsteady pressure data for 10 kHz. DSP based automatic system for pitch and yaw damping derivatives using Forced Oscillation Rig. Multi-port steady pressure measurements using 32/ 16 port scanners.
