Airbus’ twin-engine H155 (formerly the EC155 B1) is designed for a wide range of missions, including corporate, medical evacuation, search and rescue and law enforcement operations. This high-end, 5-tonne helicopter is an enhanced version of the proven Dauphin family, positioning it as the most technologically-advanced rotary-wing aircraft in its category.


Global reach

The Dauphin H155 is flown by nearly 75 operators in more than 30 countries.

Aircraft

Rotor design excellence

The H155 is a member of the renowned Dauphin family and benefits from Airbus’ advanced rotor technology, providing the lowest vibration and sound signature in its class.  

Its Spheriflex® main rotor head delivers a smooth ride – even at high speed – along with excellent handling qualities and in-flight stability. 

With the shrouded Fenestron® tail rotor, the H155 benefits from a low sound signature and low maintenance. The shrouded rotor concept delivers additional control while increasing safety during ground operations, especially in confined areas.

Durable and fast

The H155 is equipped with 2 Safran Arriel 2C2 turbine engines, which are fitted with full authority digital engine controls (FADEC) for fully automated one engine inoperative (OEI) safety. Thanks to its significant power, the H155 has a long flight range as well as the fastest cruising speed in its class.

Mission capability and durability are guaranteed by the H155’s airframe construction with highly resistant, corrosion-proof composite materials and light alloys.

The H155 offers a full-glass cockpit with large LCD screens, which reduce pilot workload, improve safety and facilitate maintenance. Two Garmin GTN 750 touchscreens are installed in the centre console for enhanced situational awareness and connectivity. 

Maintainable

The H155 benefits from years of Dauphin family experience and is designed to ensure low maintenance costs.

Its Spheriflex® main rotor head, shrouded Fenestron® tail rotor and composite tail rotor blades are designed for a long operational life and easy maintenance.  The helicopter’s Safran Arriel 2C2 turboshaft engines are of a modular design, with the installed powerplants reached by built-in steps on the aircraft and easy maintenance access.

Maintainability is further facilitated by the rotorcraft’s airframe construction with highly resistant, corrosion-proof composite materials and lightweight metal alloys.

See the HCare Services section for more information about services at Airbus.

Available on the H155 is an optional health and usage monitoring system (HUMS), along with integrated maintenance assistance based on data recording and proactive monitoring.

Missions

Private and business aviation

Known as the ‘Flying Carpet’, the H155 has become a reference on the VIP market.

The VIP transport configuration has been designed to offer the maximum level of comfort to passengers during their flight. Two wide hinged doors replace the standard sliding doors and provide spacious storage compartments. Electrical footsteps facilitate entry and egress. The cabin is fitted with an enhanced sound proofing installation, and cabin equipment - including internal and external communications - is managed through touch screen technology. 

Public services

The H155 public services configuration is an efficient and versatile configuration encompassing all pre-requisites for multi-purpose operations on land and out at sea.

Operators appreciate its large cabin, flat floor and numerous attachment points that enable quick and easy cabin conversions. Pilots enjoy the most advanced autopilot conceived for helicopters.

Emergency medical services

The H155 is a highly capable air ambulance that offers high speed, long range, accessibility and safety.

The high-set main rotor and tail rotor allow for safe ground operations, even while the rotors are turning, while the low vibration and noise levels ensure the best ride for patients.
