The Swiss indoor skydiving wind tunnel

In recent years, free fall simulators have revolutionised skydiving. The principle is based on a blower system installed in a tunnel that recreates the actual sensation of skydiving. This new human flight concept allows you to experience sensations similar to those of actual skydiving. At a height of 24 metres, the REALFLY wind tunnel is one of the largest simulators in the world and can accommodate up to 8 people simultaneously.

The concept consists of a double closed circuit in which air circulates from the bottom upwards. The airflow is produced by 4 electric motors to then be compressed in a large inverted funnel. The air is maintained at a constant temperature of 23° through the cooling system integrated in the circuit. The flight chamber of 4.35 metres in diameter is made from 5 metre high glass panels, with a usable height of 14 metres. The power of the 4 motors generates an airflow of up to 380km/h. The average flight speed is 200Km/h.
