The Institute of Aviation in Warsaw presented a film about flight tests of the Polish national team of ski jumpers, who trained in the largest wind tunnel in Poland. These are the first and only shots of this type presenting the research capabilities of this facility with the participation of athletes.

The film presents the largest in Poland and Central and Eastern Europe wind tunnel (T-3) which is located in the Aerodynamic Research Laboratory of the Institute of Aviation. The dimensions and research capabilities of the facility are impressive. The measuring space is 5 m in diameter and 6.5 m in length. Engine power (5.6 MW) and maximum air velocity (90 m / s) allow to include the Institute of Aviation tunnel into the world’s leading wind tunnel.
