test hours including more than 2,500 in flight

Reduced emissions

Arrano combines a highly efficient two-stage centrifugal compressor, developed within the European Clean Sky program, with new-design variable inlet guide vanes (IGV). Through improving the engine’s thermal efficiency, these components contribute to reducing fuel consumption by 15%, over other in-service engines.

Perfectly suited for new four-to-six tons helicopters

Arrano innovative design features a new-generation digital control system that offers greater in-flight responsiveness, enhancing both safety and pilot handling.

The gyratory combustion chamber features fuel injectors made using additive manufacturing (3D-printing) techniques. These enhance engine start performance in all weathers and altitudes, and contribute to reducing emissions.

The H160 made its first flight with the Arrano in January 2016.
