Safran Arrano 1A ready for action in US and Europe
The Safran Arrano's design features a new-generation digital control system that offers greater in-flight responsiveness, enhancing both safety and pilot handling. It is ready for installation on the H160 helicopter.
Safran Helicopter Engines is the world’s leading manufacturer of helicopter engines, with more than 75,000 produced since being founded.

Safran Helicopter Engines has received FAA type certification for its Arrano 1A engine, installed in the Airbus H160 helicopter. Arrano is a new-generation turboshaft in the 1,100 to 1,300 shp power range. It integrates the best in aero-engine technologies and offers a 15 per cent reduction in fuel consumption over other in-service helicopter engines. Arrano received EASA type certification in June 2019.

Programme director Cyrille Ressejac-Duparc says: “The Arrano is now certified in both Europe and US, and is more than ever ready for Airbus H160 entry-into-service. This engine lies at the vanguard of our new range. As well as the H160's imminent arrival in service, we are strongly committed to supporting Airbus and the French armed forces in developing the Guépard military variant.”

The Arrano's design features a new-generation digital control system that offers greater in-flight responsiveness, enhancing both safety and pilot handling. It combines an efficient two-stage centrifugal compressor, with new-design variable inlet guide vanes. Through improving the engine's thermal efficiency, these components contribute to reducing fuel consumption by 15 per cent over other in-service engines. 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. In common with all Safran engines, the Arrano is certified to operate on up to 50 per cent sustainable aviation fuel, including biofuel.

The Arrano has been designed with simple maintenance in mind and a full access to Safran Helicopter Engines digital services. Servicing time is lower than that of previous generation engines.
