• Mission

Main description

The EC155 B1 is Eurocopter’s top-end 5-ton twin-engine helicopter. It is an enhanced version of the celebrated proven Dolphin family’s with 40% more cabin space, the most advanced technologies available today and more engine power.

The twin Turbomeca Arriel 2C2 engines are optimised for high or hot conditions and are fitted with Full Authority Digital Engine Controls (FADEC) for totally automated OEI safety.

• Technologies

  Here “state of the art” really means something

  

  The EC155 B1 is a veritable cornucopia of the latest proven technologies.
  The designs for airframe and armature call for widespread use of highly resistant, corrosion-free composite materials and light alloys. Its all-composite rotors, bearingless Spheriflex main rotor head and shrouded Fenestron tail rotor combine to give it the lowest vibration and noise signature in its class.
  The EC155 B1 offers the most advanced man-machine interface available: the “Avionique Nouvelle” MEGHAS instrument panel with large LCD displays that reduce the pilot’s workload, improve safety and facilitate maintenance. The four-axis auto pilot was developed specifically for Eurocopter and is especially useful for hovering manoeuvres in high wind.
  Here “state of the art” really means something.
