TT45 PRO

Overview

TT45 PRO. Ultimate flight machine

This time we’re actually going to say it… The TT45 is “state-of-the-art” indoor skydiving recirculating wind tunnel by TunnelTech, delivering top-notch airflow quality, lowest noise emissions ever and unseen, unrivalled energy efficiency. Numerous safety features pioneered in TT45 PRO provide unparalleled flying experience to professional flyers and first-timers alike. It is a result of 20+ years dedicated to skydiving, bodyflying, instructing and wind tunnel operations management, from flyers and tunnel owners to flyers and tunnel owners.

Lowest operating expenses among sportflyersfriendly projects. The most advanced wind tunnel on the market. Best value machine.

The most technologically advanced indoor skydiving recirculating wind tunnel on the market, TT45 PRO sets new standards in the industry. Providing 12% more space compared to 14ft tunnels with circular flight chamber, it delivers superb airflow quality, whisper-quiet operation and unseen energy efficiency. Numerous safety features pioneered in TT45 PRO provide unparalleled flying experience to first timers, professional flyers and specialized military training alike.

Designed to accommodate world-class indoor skydiving events, TT45 PRO is suitable for a wide range of disciplines, including dynamic ones: 4-way dynamic, 6-way formation skydiving and up to 24-way VFS head down formations. With a maximum wind speed of up to 320 km/h (optional) and a flight chamber diameter of 4.5 meters, it provides ample space and wind power for the most demanding athletes and teams.

Its cutting-edge technology and design ensure that athletes can perform at their best, while spectators enjoy a thrilling and safe experience. The frameless 8-meter-tall glass chamber with a fully round cylindrical bottom level and an expanding conical second level provides enhanced visibility and flight monitoring. Opting for chemically strengthened glass helps avoid shattering even in case of collision with metal objects.

With a special focus on safety, TT45 features 2.1 flight chamber diffusion ratio, well-balanced safety nets with additional near-the-wall deflection, and a curved entrance to the flight chamber to avoid injuries, thus securing an enjoyable experience for novice and experienced flyers.

TT45 PRO is the most silent machine with astonishing 51dB(A) 1m in front of the flight chamber glass at belly speeds. Such minimal noise emissions allow to integrate TT45 PRO in close proximity or even within residential buildings, mixed use and retail developments.

As energy consumption is a crucial factor in indoor skydiving projects, TT45 PRO boasts exceptional 255-300kW for the belly speed, ensuring lowest power consumption across 14ft class and minimal operating costs among sport flyers-friendly projects. High level of energy efficiency is granted by the overall design, which includes 4 extra-large axial fans with carbon fiber blades situated in the vertical airducts. This wind tunnel is ideal for countries with high energy costs and for environmentally conscious operators.

To ensure a comfortable environment for flyers, regardless of the weather outside, TT45 PRO is equipped with an outright ventilation system and an optional active cooling system. For mild and cold climate locations, outright ventilation allows to additionally increase energy savings up to 35%. For hot climate zones turbulence-free cooling is provided through the hollow turning vanes.

Investing in a TT45 PRO wind tunnel ensures a future-proof, world-class indoor skydiving experience for both entertainment and professional flyers. Its advanced safety features, exceptional performance, and outstanding energy efficiency make it the ultimate choice for any project, from shopping malls to dedicated skydiving centres.
