Overview
Impressively spacious, TT52 PRO offers a unique and exhilarating flying experience for both amateur and professional flyers. The enlarged flight chamber allows to practice all modern indoor skydiving competition disciplines including 8-way formation and dynamic disciplines. TT52 PRO is the perfect venue to host world championships and other high-level indoor skydiving competitions. Its exceptional performance, safety, and energy efficiency make it an attractive choice for event organizers and competitors alike. Best suitable for highly populated areas with competing 14ft indoor skydiving projects.
The large 5.2-meter-diameter flight chamber provides an overwhelming area to experience indoor skydiving at its best. The multi-level glass section comprises of a 4-meter-tall cylindrical bottom part and a 4-meter-tall conical upper part. The frameless design allows the best views for both flyers and spectators. Transparent and exceptionally durable chemically strengthened glass guarantees maximum safety even during training sessions with metal gear.
TT52 PRO is an extremely powerful machine suitable for sport training in groups up to 8 persons and military training with full gear. Operational costs are a significant factor in the success of any indoor skydiving project, especially when it comes to big-sized wind tunnels. TT52 PRO’s enhanced aerodynamic design includes 4 extra-large low RMP axial fans with carbon fibre blades located in the vertical air duct. This design benefits the energy efficiency, ensuring lower running costs and a greener approach to indoor skydiving.
Putting safety at the forefront, TT52 PRO features 1.9 flight chamber diffusion ratio, innovative safety net with near-the-wall deflection, and a curved collision safe entrance to the flight chamber. Highly praised by pro flyers, these features create the most secure environment for those who have no experience in indoor skydiving.
World Championship Suitability
The TT52 is the perfect venue to host world championships and other high-level indoor skydiving competitions. Its large flight chamber and industry-leading height enable dynamic disciplines and provide an unparalleled flying experience for athletes. The exceptional performance, safety, and energy efficiency features of the TT52 make it an attractive choice for event organizers and competitors alike.
With its cutting-edge technology and design, the TT52 is a top choice for any indoor skydiving project. From shopping malls to dedicated skydiving centers, the TT52 offers a world-class experience that attracts enthusiasts and casual flyers alike. With its visually striking appearance and exceptional flying capabilities, this wind tunnel is a fantastic investment for businesses looking to create unforgettable experiences for their customers.
To provide a comfortable flying experience in any climate zone, TT52 PRO comes equipped with both an outright ventilation system and an optional active cooling system. In regions where low temperatures are predominant, the ventilation system can further enhance energy efficiency, leading to additional savings of up to 35%. Cooling the airflow is essential for hot climate zones. The active cooling system involves hollow turning vanes that effectively cool the air while keeping the airflow quality at the top.
