Airbus’ twin-engine H155 (formerly known as the EC155 B1) is designed for a wide range of missions, including private and business aviation, emergency medical services (EMS), and law enforcement operations. This five-tonne helicopter is an enhanced version of the proven Dauphin family.

Global reach

The H155 is flown by 70-plus operators in more than 30 countries.

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.

This helicopter’s 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 liquid crystal display (LCD) screens, which reduce pilot workload, improve safety, and facilitate maintenance. Two Garmin GTN 750 touchscreens are installed in the centre console, enhancing 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.

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