FRP ducts

Our ducts, including all diffusers and the contraction, are perfectly aerodynamic in shape and are made of thick (90 mm) fibre-reinforced plastic (FRP) sandwich, resulting in:

  • No vibration
  • Reduced noise
  • Reduced drag
  • Increased overall tunnel performance

Axial fans

  • Among the largest in the industry
  • Low noise
  • Low vibration
  • Ultra efficient

Honeycomb

Our honeycomb straightens the airflow just before the flight chamber, for extra smooth flights.

It is designed to offer the best performance and efficiency.

-

Turning vanes

Unique shape to turn the airflow without introducing much turbulence

Extra-large for greater efficiency

Made of extruded aluminium: light and strong

Cool the air inside the tunnel to ensure a comfortable flight
