TT32 µFly

Overview Specification Projects Documentation

Overview

TT32 μFLY is the largest model among the μFLY Series wind tunnels, aimed at novice flyers. Boasting an enlarged 3.2-meter diameter flight chamber, it is meticulously engineered to offer a high-quality and cost-effective indoor skydiving solution for projects in the entertainment sector.

A 7,5-meter-tall glass flight chamber ensures a more exciting experience for both participants and spectators. Its conical design prioritizes safety for first-time flyers, providing stability and eliminating risks of uncontrolled high-speed ascents. Chemically strengthened glass makes the environment shatterproof for mayor confidence of flyers and operators.

Although TT32 μFLY provides a larger flight area, it remains a super compact solution with minimum footprint and great performance. Powered by one extra-large axial fan, it minimizes energy costs while proving enough wind speed for intermediate freefly training and head-up flying. The strategic placement of the fan within the vertical air duct, combined with the use of carbon fiber blades, significantly elevates energy efficiency and contributes to a more eco-friendly, quiet and cost-effective operation.

The integrated active cooling system ensures a consistently comfortable flying experience by delivering smooth, turbulence-free cooling via hollow turning vanes, regardless of external temperatures.

Thanks to its innovative modular design, TT32 μFLY doesn’t require large-scale construction works and allows trouble-free assembly, reducing both installation time and labor expenses. A great choice for the projects with spatial constraints or budget limitations.

TT32 μFLY is a versatile and adaptable wind tunnel solution that caters to various applications and settings including entertainment venues, shopping centers, educational institutions. Whether your goal is to diversify your entertainment offering, attract crowds and enhance foot traffic within your shopping complex, foster curiosity and STEM learning, TT32 μFLY guarantees success.

Apart from entertainment flyers TT32 μFLY holds a special appeal for skydivers. By offering advanced training sessions and accommodating skydivers during off-peak hours, you can maximize your revenue potential and optimize the wind tunnel’s occupancy, ensuring that the TT32 μFLY remains a valuable and profitable asset for your project.
