Introduction
Airbus Helicopters’ twin-engine H155 (formerly the EC155 B1) is designed for a wide range of missions, including corporate, offshore transport, medical evacuation, search and rescue and police operations. This high-end, five-ton helicopter is an enhanced version of the proven Dauphin family, positioning it as the most technologically-advanced rotary-wing aircraft in its category.
Rotor design excellence
The H155 benefits from Airbus Helicopter’s advanced, proven rotor technology, providing the lowest vibration and sound signature in its class. Its distinctive design – from the refined nose to its rear “dorsal fin” – clearly distinguishes the H155 as a member of the renowned Dauphin family.
Its Spheriflex® main rotor head delivers a smooth ride – even at high speed – along with excellent handling qualities and in-flight stability. The high efficiency profile of its all-composite five blade main rotor allow greater lift and speed.
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 two Turbomeca 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 fully glass cockpit with large LCD screens, which reduce pilot workload, improve safety and facilitate maintenance.
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 rotor blades are designed for a long operational life and easy maintenance. The helicopter’s Turbomeca 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.
Available on the H155 is an optional full health and usage monitoring system (HUMS), along with integrated maintenance assistance based on data recording and proactive monitoring.
