The photo captures the installation of a main axial fan unit for the Luxfly wind tunnel in Luxembourg. The assembly features a large-diameter rotor with carbon-fiber blades mounted on a vertical axis. A crane positions the fan component within the ductwork, surrounded by the facility's red steel support structure. This component powers the airflow for a TunnelTech TT45 PRO system.

The image shows the assembly process of the structural components for the Luxfly building, including the iconic pink load-bearing beams.

The photo shows the glass-plastic components of the TT45 Pro wind tunnel's airjet (confusor) under assembly at the Luxfly facility. These elements are part of the aerodynamic system designed for stable, low-turbulence airflow.

The image shows the final assembly of the turning vanes in the lower duct section of the Luxfly wind tunnel. Turning vanes are used to redirect airflow efficiently within the recirculation loop, minimizing turbulence and pressure losses.

Installation and assembly of the confuser in the flight chamber of the TT45 Pro wind tunnel. The Confuzor is a critical aerodynamic component that ensures smooth airflow transition into the flight chamber.

A technician positions a curved FRP air duct section containing turning vanes during the assembly of the Luxfly wind tunnel. This component forms a corner of the TT45 PRO recirculating loop, designed to redirect airflow within the concrete structure. The installation process involves precise alignment of the composite ductwork using rigging chains to fit the building envelope.

Two installation technicians equipped with safety harnesses and rigging gear stand on the structural steel framework during the construction of the Luxfly indoor skydiving facility in Luxembourg. The personnel perform rigging operations at height to align the TunnelTech TT45 PRO wind tunnel components with the building's distinct pink bearing structure. To the right, the exterior surface of the vertical wind tunnel assembly is visible adjacent to the steel beams.

Large blue fan housing units containing stator vanes await installation at the Luxfly wind tunnel site in Luxembourg. A mobile crane operates adjacent to the facility's distinctive pink steel bearing structure. These heavy mechanical components form the static section of the axial fan assembly for the TT45 PRO system. The construction team stages the equipment on the ground before lifting it into the facility's return duct loop.
