Airbus Helicopters H160
The Airbus Helicopters H160 (formerly X4) is a medium utility helicopter being developed by Airbus Helicopters. Formally launched at Heli-Expo in Orlando, Florida on 3 March 2015, it is intended to replace the AS365 and EC155 models in the firm's lineup. In June 2015, the first test flight took place; the first customer deliveries are expected to occur in 2018.
==Development==
The Airbus Helicopters H160 was first revealed to the public in 2011, at which point it was referred to by company representatives by the designation X4 – a designation which implied it to be a follow-on from the Eurocopter X3, a high-speed hybrid helicopter technology demonstrator. Speaking in early 2011, Eurocopter (later renamed as Airbus Helicopters) chief Lutz Bertling declared that the X4 would be a "game changer", contrasting significance of the innovations it would feature with Airbus' development of fly-by-wire controls.〔Thisdell, Dan. ("Eurocopter X4 promises technical tour-de-force." ) ''Flight International'', 1 March 2011.〕 Early features alluded to included ''Blue Edge'' active tracking rotor blades, advanced pilot assistance functionality, and reduced vibration to "near-jet" levels of smoothness.〔 The X4 was also described as having a "radically different" cockpit, Bertling stating that "The cockpit as we know it today will not be there". It was also announced that the X4 would be introduced in two stages: an interim model in 2017 with some of the advanced features absent, and a more advanced model following in 2020.〔Quick, Darren. ("Eurocopter plans next-generation X4 helicopter." ) ''gizmag'', 13 February 2012.〕
The development program for the X4 cost €1 billion ($1.12 billion), even after numerous cutting-edge features, including proposed highly advanced control systems, were toned down or eliminated as too risky or costly.〔〔 On 3 March 2015, the X4 was formally unveiled under the H160 designation. It has been marketed as a successor to the company's existing Eurocopter AS365 Dauphin and competes with the AgustaWestland AW139, Sikorsky S-76 and Bell 412;〔 Guillaume Faury, Airbus Helicopters Chief Executive, called the H160 "the AW139 killer".〔Perry, Dominic. ("Airbus Helicopters targets AW139 with new H160" ) ''Flight International'', 3 March 2015.〕〔("Airbus Helicopters H160: The Evolutionary Successor." ) ''Seeking Alpha'', 6 October 2015.〕 The H160 began Airbus Helicopter's re-branded naming convention; starting 1 January 2016, helicopters in the same range shall bear the 'H' designation, resembling how Airbus names their commercial aircraft.〔
During development, emphasis was placed on using Airbus' production and support techniques as used for advanced fixed-wing aircraft such as the Airbus A350 passenger jet; accordingly, a pair of test rigs were built to separately test the dynamic and system elements respectively to speed up the design process.〔 On 29 May 2015, the first H160 prototype was unveiled at Airbus Helicopters' Marignane facility in France.〔("Airbus Helicopters unveils H160 prototype." ) ''Vertical Magazine'', 1 July 2015.〕 On 13 June 2015, the first prototype performed its first flight from Marignane. By November 2015, the flight envelope of the prototype had been progressively expanded, having attained a maximum altitude of and a maximum speed of so far.〔("Airbus H160 Makes Dubai Show Debut." ) ''Aviation Week'', 8 November 2015.〕 In November 2015, certification of the H160 and its entry into service with civil operators are both scheduled to take place in 2018; a military-orientated variant, designated H160M, is aimed to enter service in 2022.〔Perry, Dominic.
