Airbus Helicopters has been running with two turboshaft engine options, Pratt & Whitney Canada’s PW210E and Turbomeca’s Arrano, since the first design concept in 2012. But following the end of the preliminary phase of development, the company has now revealed that it, “has decided to amend the product positioning, consequently necessitating a significant engine power increase.”
According the Airbus Helicopter, Pratt & Whitney did not wish to continue with a growth path for the PW210E engine, while Turbomeca was willing to commit to the uprating of the Arrano. It is this engine that will now go forward into the X4’s full-scale development program.
