The '''Airbus Helicopters H155''' (formerly '''Eurocopter EC155''') is a long-range medium-lift passenger transport [[helicopter]] developed by [[Eurocopter]] from its [[Eurocopter Dauphin|Dauphin]] family for civil aviation use. It is a twin-engined aircraft and can carry up to 13 passengers along with 1 or 2 crew, depending on customer configuration. The helicopter is marketed for passenger transport, offshore support, [[Very Important Person|VIP]] corporate transport and casualty transport duties. In 2015, the EC155 was formally renamed to the H155, in line with Eurocopter's corporate rebranding as [[Airbus Helicopters]].<ref>[http://www.airbushelicopters.com/website/en/press/Meet-the-H-Generation_1713.html "VIDEO: Meet the H Generation."] ''Airbus Helicopters'', 3 March 2015.</ref> It was succeeded in the product line by the [[Airbus Helicopters H160]].

==Development==

Originally designated AS365 N4, the EC155 was developed from the [[Eurocopter Dauphin|Eurocopter AS365 N3 Dauphin 2]] with the aim of significantly increasing the cabin space of the Dauphin. Development began in September 1996 with the helicopter officially announced by Eurocopter at the [[Paris Air Show]] in June 1997. The first EC155 helicopter, a modified [[Eurocopter Dauphin|Dauphin]] airframe, made its maiden flight at [[Marignane]] on 17 June 1997 and the first pre-production EC155 B flew on 11 March 1998. The aircraft received safety certification by the French and German civil aviation authorities on 11 December 1998 and went into production soon after.

In March 1999, deliveries of the EC155 B commenced, the [[German Federal Police]] became the first operator of the type. Between March 1999 and June 2003, roughly 50 EC155 Dauphins were sold, mainly to [[VIP]] and off-shore customers.<ref name = "ec155 power">[https://www.flightglobal.com/pdfarchive/view/2003/2003%20-%201232.html "Eurocopter may power up EC155 to boost sales."] ''Flight International'', 2 June 2003. p. 6.</ref>

The EC155 B1 was developed with uprated engines, giving it improved performance at high altitude and in hot temperature conditions; this derivative also features a higher maximum take-off weight (10,846&nbsp;lb vs. 10,580&nbsp;lb). Deliveries of this model began in November 2002 with the [[Government Flying Service (Hong Kong)|Hong Kong Government Flying Service]] becoming the first operator. In early 2003, Eurocopter completed studies for an even more powerful version of the EC155 B1, designed to better compete with new rotorcraft such as the [[AgustaWestland AW139]] and to better meet military customer's requirements.<ref name = "ec155 power"/>

Several major elements of the EC155, such its rotor system (albeit modified to operate at slower rotational speeds), were used in the [[Eurocopter X3]], an experimental high-speed compound helicopter which set an unofficial speed record of {{convert|255|kn|mph km/h}} in 2013.<ref name=nelms>Nelms, Douglas.

[[File:KAI LAH-1 Miron Armed Helicopter - 2.jpg|thumb|[[KAI LAH-1 Miron]] armed helicopter]]

In 2015, Airbus Helicopters and [[Korean Aerospace Industries]] (KAI) formed an agreement to transfer principle manufacturing activity for the EC155 to [[South Korea]]; KAI shall become the sole manufacturer of the type after 2018, and both firms shall be jointly involved in the international marketing and further development of the type. The EC155 is to serve as the basis for KAI's [[KAI LCH|Light Civil Helicopter (LCH)]] and [[KAI LAH|Light Armed Helicopter (LAH)]], featuring numerous changes including a new cockpit, improved gearbox and rotor blades; the LAH shall have a chin-mounted 20&nbsp;mm cannon and side-mounted guided rockets, countermeasures systems, and be able to carry 6–10 combat troops. The LCH is to enter service in 2020, and the LAH will follow in 2022 to replace the [[MD 500 Defender]] and [[AH-1 SuperCobra|AH-1J/S Cobra]]. Airbus foresees a South Korean demand for 100 LCHs and 214 LAHs, and estimates an international market of 300–400 LAH versions to replace legacy attack helicopters.<ref name = "flight kai pics">Waldron, Greg.

==Design== [[File:EC155 B1.jpg|thumb|right|EC155 B1 of [[Kingfisher Airlines]] in India]]

The EC155 B features a completely redesigned cabin providing 30% more passenger space than previous [[Eurocopter Dauphin|Dauphin]] helicopter models, plus a 130% increase in baggage hold volume. Other major improvements include a five-blade Spheriflex [[Composite material|composite]] main rotor combined with the familiar shrouded [[Fenestron]] [[tail rotor]] to reduce vibration levels significantly. The EC155 B is powered by two 635&nbsp;kW (851 shp) [[Turbomeca]] [[Turboméca Arriel|Arriel 2C1]] [[turboshaft]] engines which feature a dual-channel [[FADEC|Full Authority Digital Engine Control (FADEC)]] system. The EC155 B1 features uprated 697&nbsp;kW (935 shp) Arriel 2C2s. The helicopter can be fitted with an [[Deicing|anti-icing]] system to enable the aircraft to operate in very cold climates. The [[Glass cockpit|all-glass cockpit]] is equipped with an 'Avionique Nouvelle' integrated digital flight control system featuring Eurocopter's Vehicle and Engine Management Display (VEMD), which utilizes [[Active-matrix liquid crystal display|active matrix liquid crystal displays]]. The EC155 is also equipped with a four-axis digital autopilot, coupled to the engine FADECs for full-envelope protection, and is offered with a Health and Usage Monitoring System (HUMS).<ref>Gray 2000, pp. 48–49.</ref>

Eurocopter designed the EC155 originally with three configurations, however, another two configurations were added in 2005. The Passenger Transport version can carry 12 passengers in comfort seats or 13 passengers in utility seats, along with 1 or 2 crew. The [[Very Important Person|VIP]] or Corporate Transport version has a VIP lounge with working space accommodating up to 8 executives. The Casualty Transport version can carry 2 stretchered patients with up to 4 seated medical staff, or 4 patients on stretchers plus 2 seated medical staff. The configurations added in 2005 were for offshore operation and police and parapublic missions ranging from patrol, airborne surveillance, [[Search and rescue|SAR]] and [[Emergency medical services|EMS]], the helicopter being fitted with specific mission equipment for these duties.<ref name ="gray 48">Gray 2000, p. 48.</ref>
