• Mission

Main description

Versatility and comfort, the best of both worlds.
The EC155 B1 is Eurocopter’s high end 5-ton twin-engine helicopter. It is an enhanced version of the proven Dauphin family and boasts the most advanced technologies available.
The EC155 B1 has a five-bladed Spheriflex® rotor head with an extremely low vibration level. Equipped with Eurocopter’s famous Fenestron® tail rotor, the EC155 B1 performs with a noise level that falls 4.6 dB below ICAO level. It’s so quiet that passengers feel as if they are travelling in a business jet.

• Technology

   
  At the Forefront of New Technology

  The EC155 B1 airframe is constructed of highly resistant, corrosion-proof composite materials and light alloys. With its all-composite rotors, Spheriflex® main rotor head and Fenestron® tail rotor, the EC155 B1 has the lowest vibration and noise signature in its class. The EC155 B1 offers a fully intuitive glass cockpit with large LCD displays, which reduce the pilot’s workload, improve safety and facilitate maintenance. The superb Eurocopter designed 4-axis auto pilot gives outstanding hover performance in extreme conditions; in flight it holds altitude, speed and heading to the finest limits.
