The Low Turbulence Wind Tunnel TMT

The Low Turbulence Wind Tunnel is an atmospheric, open-circuit tunnel with two linked, closed, rectangular test sections. 

The tunnel was equipped with two DC motors with the power of 5.1 kW and 64 kW, used depending on the preset measurement speed of the working medium.

Low Turbulence Wind Tunnel TMT – scope of services

  • weight and pressure distribution tests on the following models:
    • aircraft, 
    • helicopters, 
    • vehicles on rails, 
    • wheeled vehicles and their elements;
  • optimization of flap geometry and their position,
  • optimization of hinge moments for ailerons and control surfaces,
  • flow visualization using imaging anemometry (PIV), thread methods, and using fluorescent mini-threads and UV illumination;
  • smoke flow visualization,
