Instead the X4 will enter into the full-scale development with a new uprated 1100 shp Turbomeca ARRANO turboshaft engine (pictured).
Airbus Helicopter's launched the X4 new generation medium twin-engine helicopter in 2012, with the initial design concept around two engines options: Pratt & Whitney Canada’s PW210E and Turbomeca’s ARRANO.
Airbus says upon a comprehensive market assessment, it decided to amend the product positioning, consequently necessitating a significant engine power increase.
Its major benefit is a 10 to 15% reduction in fuel consumption, compared with previous generation engines.
Airbus said the P&WC will continue to provide support until completion of the initial phase.
The X4 will be tailored for a wide range of applications, including oil and gas operations, emergency medical services, public services, business and private aviation.
Airbus is slated to unveil the X4 for the first time at Heli-Expo 2015 on the 3rd of March.
First bench testing of the Arrano took place in February 2014. Type-certification is in-line with the milestones of the X4 helicopter.
