TT43 Smart Fly


TT43 Smart represents a top-quality budget-friendly wind tunnel solution for venues combining entertainment and sport training aspects. It fulfills the needs of a wide range of customers: from thrill-seekers to professional flyers. As a full-size 14ft class wind tunnel, TT43 Smart is well-equipped to host FAI world-class competitions, including 4-way formation skydiving and dynamic disciplines. Delivering stable and consistent airflow, minimized noise levels, and safety for highspeed disciplines, TT43 Smart ensures an enjoyable experience for both flyers and spectators.

Its 4.3-meter-diameter flight chamber easily accommodates larger groups of skydivers for training sessions. The height of the glass section is 4 meters. The cylindrical shape provides enough room for the flyers to perform maneuvers and allows spectators to follow the action up close. Chemically strengthened glass ensures safety and impact resistance during high-speed activities.

TT43 Smart is equipped with two extra-large axial fans with carbon fiber blades to provide high airflow speeds. Positioned in the vertical air ducts, the fans contribute to remarkable energy efficiency while maintaining a low noise level.

The integrated active cooling system ensures comfortable temperatures inside the wind tunnel, regardless of external conditions. Cooling the airflow through the hollow turning vanes doesn’t generate neither turbulence nor energy losses.

TT43 Smart is the financially viable solution for entertainment flights, training programs and international competitions. This model effortlessly combines quality, affordability, versatility, and high-energy efficiency, making it an excellent option for your project.
