Title: Wind tunnel for training parachutists

Abstract: A wind tunnel is provided usable for training of sportsmen-parachutists and entertainment purposes. The tunnel comprises a channel, including sequentially arranged and interconnected components: an input confusor, a first working zone, an intermediate confusor, and a second working zone. The working zones are shaped as diffusers, having different longitudinal flow speed gradients, so that the working zone having the lesser longitudinal speed gradient is shorter, whereas the working zone having the greater longitudinal speed gradient is longer. A honeycomb is arranged between the working zones. The entrances and exits of the working zones are equipped with safety nets. The structural design of the tunnel makes it possible to simultaneously train parachutists for team acrobatics and artistic types of parachuting under conditions, maximally adapted to a given type of training, thereby improving a training quality and substantially increasing the tunnel's cost effectiveness.
