| Sub-category of Aerospace Test | NA | |
| Year of Establisment | NA | |
| Test Applications | A wind tunnel to study the aerodynamic characteristics of surface and submerged platforms and underwater weapons with test section of 1.5 x 1.5 x 4 m. A maximum speed of 60 m/sec can be produced with a 125 kW fan in this wind tunnel. The Wind Tunnel is equipped with projection manometers, differential pressure transducers, velocity measuring probes, vertical catheto-meters, hot film anemometers, 48 port Scanivalve traversing gear as well as PC based data acquisition system and analysis software packages. |
