Wind tunnel Ø 3.0
The system is made of metal with profiled elements and a steel support frame. It features high aerodynamic quality that positively influences the speed and quality of the airflow and also the economic performance. The (Max) speed of the airflow is not less than 75 m/s.
ABOUT THE PRODUCT
DESCRIPTION / TECHNICAL CHARACTERISTICS
Ø 3.0 vertical wind tunnel is intended both for entertaining flights as well as for trainings and competitions of sportsmen at all skill levels. It has a closed double-circuit configuration which is standard for the devices of its class, and is equipped with a cooling system allowing using it independently of climate, seasons and weather.
The design includes cooled vanes of rotary units and a nozzle with high contraction ratio (3,4). In general, the electric motors and the closed configuration of the system enable excellent ecological characteristics, low noise level and operating convenience.
An advantageous feature of Ø3.0 is the location of the motors with fans on shafts directly in the tunnel channels. This results in a design free of external motor sections as well as a transmission, which makes the wind tunnel more compact, reliable and durable.
The wind tunnel can be easily assembled and disassembled and can be transported in standard sea containers to any location in the world. The total weight of the system is 58 t.

INSTALLATION AND OPERATION
Service life of our wind tunnels is determined by the actual state of the system: but not less than 10 years The tunnel has 3 years limited warranty and individual units are subjects to the warranty of a corresponding manufacturer. The period between the maintenance service of the fans is 2000 hours, with periodic inspections as specified in the manual.
Service life extension for the fans is possible.
In addition, our company provides a 50% discount on the course of professional training of instructors with the skills of a technical specialist. Training is carried out by highly qualified athlete’s instructors. The training program consists of 30 hours, including 15 hours of theory, 15 hours of practical skills. The training course includes acquaintance with the technical characteristics and the device of the wind tunnel, which will allow inspection and maintenance. The cost of flight time is paid by the customer.
The support frame consists of steel tubes with bolted and welded connections. It bears the power units and cooling heat exchangers. It provides stability and rigidity of the whole wind tunnel structure.
The support frame is mounted directly on the foundation. The foundation is constructed according to the Design Documentation provided by the Manufacturer.
Air channels provide the airflow circulation inside the wind tunnel with the minimum aerodynamic resistance.
The structure of the air channels is reinforced by the support frame.
All metal surfaces in the wind tunnel are painted according to the color scheme (without images) approved by the Buyer.
Dimensions: the flight chamber is a transparent cylindrical chamber (glass) with the internal diameter of 3000 mm and the height of 7200 mm. A non-transparent expanding chamber is located above the cylindrical part. Transparent section of the flight chamber (with the height not less than 5700 mm) is made of the tempered triplex with thickness of 17 mm or greater and consists of two segments connected by a metal ring.
• The lower segment has entrance consisting of a metal frame, a door and side inserts. The entrance is connected to the transfer chamber, also made of cylindrical glass windows inserted into metal frames. Doors of the flight chamber and the transfer chamber are equipped with electric drives.
• Safety Nets: the flight chamber is restricted with safety nets from the top and the bottom. The bottom net has a mesh of 60х60 mm. (rope with D of 3 mm). The safety nets are mounted in a way to provide easy access for the service and repair.
CP – a wind tunnel operator’s station, includes the following elements:
• Digital control panel for the frequency converters/motors, switch for the electric drive of the cooling flaps, switch for the electric drive of the flight chamber door, switches (4 groups) for the flight chamber illumination; • PC connected to CPU (via USB, RS-232); • SW (it displays the actual operating parameters of the motors and wind tunnel systems including motors RPM, currents, flight time and temperature in the flight chamber).
