A vertical wind tunnel (VWT) is a wind tunnel which moves air up in a vertical column. It is a recreational wind tunnel, frequently advertised as "indoor skydiving" or "bodyflight". It is also a popular training tool for skydivers.
Vertical wind tunnels enable human beings to fly in air without planes or parachutes, through the force of wind being generated vertically. Wind moves upwards at approximately 195 km/h (120 mph or 55 m/s), the terminal velocity of a falling human body belly-downwards, although this can vary from person to person. A vertical wind tunnel is frequently called 'indoor skydiving' due to the popularity of vertical wind tunnels among skydivers, who report that the sensation is extremely similar to skydiving. The human body 'floats' in midair in a vertical wind tunnel, and this is called 'body flight' or 'bodyflight'.
Vertical wind tunnel types :
All vertical wind tunnels can be classified as follows:
Vertical wind tunnels with outdoor or open-air flying experience.
Hybrid custom-made wind tunnels where wall-to-wall and open-air experience is combined in one technology.
Outdoor vertical wind tunnels can either be stationary or portable. Portable vertical wind tunnels are often used in movies and demonstrations, and are often rented for large events such as conventions & state fairs. Portable units offer a dramatic effect for the flying person and the spectators, because there are no walls around the flight area. These vertical wind tunnels allow people to fly with a full or partial outdoor/sky view. Outdoor vertical wind tunnels may also have walls or netting around the wind column, to keep beginner tunnel flyers from falling out of the tunnel.
