Safran Helicopter Engines’ Arrano 1A engine has received type certification from the European Aviation Safety Agency (EASA).

Arrano, installed on the Airbus Helicopters H160, is a new generation engine in the 1,100 to 1,300 shp power range, designed for new four-to-six tonne helicopters. The H160 made its first flight with the Arrano in January 2016.

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%, over other in-service engines. The gyratory combustion chamber features fuel injectors made using additive manufacturing techniques. These enhance engine start performance in all weathers and altitudes, and contribute to reducing emissions.

Bernard Fujarski, Airbus Helicopters H160 programme director, said: ‘Arrano is a major asset of the H160 and one that is fully aligned with the programme’s overall ambition of bringing innovations for greater customer satisfaction, thanks to its lower fuel consumption, its high level of performance, and its maintenance plan that has been harmonised with that of the helicopter’s. Its certification passes a new milestone on the helicopter’s entry-into-service roadmap.’
