Airbus’ twin-engine H155 (formerly EC155 B1) is designed for a wide range of missions, including private and business aviation, EMS, and law enforcement operations. This five-tonne helicopter is an enhanced version of the proven Dauphin family.
Rotor design excellence
The H155 belongs to 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.
Thanks to the shrouded Fenestron® tail rotor, the H155 benefits from a low sound signature and low maintenance. The shrouded rotor concept delivers additional yaw control while increasing safety during ground operations, especially in confined areas.
Sustainable and fast
The H155 is equipped with two Safran Arriel 2C2 turbine engines fitted with dual channel 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.
Durability and mission capability are guaranteed by the H155’s airframe components made of 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 touch screens are installed in the centre console and enhance situational awareness and connectivity.
Maintenance attributes
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 engine’s integration has a decisive impact on maintenance; built-in steps provide easy access to the engines and main gearbox, while the modular design of the Safran Arriel 2C2 engines allows maintenance to be carried out in stages.
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.
Private and business aviation
Known as the ‘Flying Carpet’, the H155 has become a reference on the VIP market.
In its VIP configuration, the H155’s two wide hinged doors replace the standard sliding doors, giving access to spacious storage compartments. Electric footsteps ease passengers’ entry and exit from the aircraft, while the cabin is fitted with enhanced soundproofing for greater well-being in flight. Cabin equipment - including internal and external communications - is managed through touchscreen technology.
Public services
The H155 public services configuration is an efficient and versatile configuration encompassing all prerequisites 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.
