Versatility and comfort: the best of both worlds
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.
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.
Private and business transportation
Elegantly designed, the H155 combines beauty and functionality. Its wide, unobstructed cabin accommodates two pilots and up to 12 passengers in a comfortable cabin layout. The corporate configuration seats nine passengers, while a VIP arrangement holds up to eight passengers.
The two extra-wide passenger doors with full-length boarding steps facilitate easy access to the cabin, and the large baggage compartment is conveniently accessed from both sides of the aircraft, allowing quick loading of bulky luggage. In flight, passengers appreciate panoramic views offered by the large windows.
The fully-modular, spacious interior can be outfitted with extra-thick insulation and special flooring. The result is a pleasant cabin atmosphere, conducive to work, conversation or relaxation. High-end options include soft leather club seats, power sources for laptops, adjustable reading lights, cabin air-conditioning and air outlets for each passenger, along with such amenities as satellite communications and in-flight entertainment.
Oil and gas transportation
The H155 benefits from Airbus Helicopters’ design and operational expertise as a leading helicopter supplier to the global oil and gas industry. This rotorcraft fulfils the most stringent safety requirements for missions to offshore platforms, with full authority digital engine controls (FADEC), a four-axis automatic flight control system and cutting-edge digital avionics to reduce pilot workload and support the highest levels of flight safety.
Thanks to its high speed, compact airframe, high-set set main rotor and shrouded tail rotor, the H155 is suited for even small, busy landing sites on land and at sea. The wide cabin’s low internal sound and vibration levels and comfortable seating for as many as 12 passengers and two pilots make it an ideal aircraft for long-haul missions and inter-rig shuttle transportation.
Optional equipment available to meet oil and gas industry standards include external life rafts, a traffic alert collision avoidance system (TCAS) and enhanced ground proximity (GPWS), cockpit voice and flight data recorders, along with health and usage monitoring systems.
Law enforcement, search and rescue
The H155's high speed and long endurance make it an ideal tool for law enforcement duties ranging from patrol and the airlift of special weapons (SWAT) teams to surveillance and air support for ground operations. This rotorcraft also is well suited for search and rescue missions.
With the largest cabin and lift capacity in its class, the H155 can transport police units of up to 12 members to the incident area. Equipment can easily be loaded into the large baggage compartment. The H155 offers unmatched visibility and a discrete sound level for effective surveillance operations.
Its state-of-the-art glass cockpit is compatible with night-vision goggles, which makes it fully available night and day. The four-axis automatic flight control system maximizes the pilot’s effectiveness for highly demanding missions.
Mission equipment includes a moving map display, an electrical hoist and rappelling system, cargo sling with electrical external mirrors, an electro-optical day and infrared cameras and external loud speakers.
Emergency medical services
The H155 is a highly capable air ambulance that offers high speed, long range, accessibility and safety.
Its large, unobstructed cabin has sufficient space for multiple patients, medical personnel and their equipment – accommodating up to two stretchers with four seats for medical crews. Extra-wide sliding doors and full-length boarding steps make loading rapid and smooth.
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.
