Safran Helicopter Engines’ Arrano 1A has received FAA type certification for installation in the Airbus H160 medium twin helicopter, clearing the way for that helicopter’s entry into service shortly. The engine received EASA approval in June 2019.
The 1,100- to 1,300-shp Arrano features reduced maintenance, new digital controls, a two-stage centrifugal compressor, and variable inlet guide vanes that combine to reduce fuel consumption by more than 15 percent and reduce emissions compared to comparable engines, according to the manufacturer. The gyratory combustion chamber features 3D-printed fuel injectors that improve engine start performance. The Arrano is certified to operate on up to a 50 percent sustainable aviation fuel blend.
