  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.
  Test Special Features
 Flow visualization and boundary layer studies for underwater vehicles.
Wake survey and velocity distribution behind a body for propulsor development.
Pressure and velocity distribution over axi-symetric bodie.
Estimation of forces and moments on control surfaces of a submerged body, etc.
