FIELD: testing equipment.
SUBSTANCE: invention is related to the field of aerodynamics and may be used for aerodynamic research, preparation of sportsmen-parachute jumpers and other purposes. Device comprises confuser, working zone, diffuser, one or several return channels, ventilator plant and rotary bends with different angles of flow turn. At the same time bend with smaller angle of flow turn is installed in section, where speed of flow is higher, and bend with higher angle of flow turn is installed in section, where flow speed is lower.
EFFECT: reduction of hydraulic losses, reduction of drive efficiency and metal intensity of structure.
