EASA Certifies Safran Arrano 1A Engine Powering H160 Helicopter

Jul 15,2019

Safran Helicopter Engines has received EASA (European Aviation Safety Agency) Type Certification for its Arrano 1A engine, installed in the Airbus Helicopters H160. Arrano is a new generation engine in the 1,100 to 1,300 shp power range, perfectly suited for new four-to-six tonne helicopters. The H160 made its first flight with the Arrano in January 2016.

Arrano Program Director Cyrille Ressejac-Duparc said, "we are proud to announce Arrano certification here at le Bourget. This engine lies at the vanguard of Safran Helicopter Engines' new engine range and its performance is unrivalled. It features low operational and support costs, easy maintenance and a lower environmental footprint. After a test campaign of 10,000 hours, including 2,000 in flight, we are now ready to support H160 entry-into-service. Safran Helicopter Engines is also strongly committed to developing the HIL (H¨¦licopt¨¨res Interarm¨¦es L¨¦gers) military variant".

"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 harmonized with that of the helicopter's, . Its certification passes a new milestone on the helicopter's entry-into-service roadmap", said Bernard Fujarski, Airbus Helicopters H160 Program Director.

Arrano integrates the best in aero-engine technologies. Its innovative design features a new-generation digital control system that offers greater in-flight responsiveness, enhancing both safety and pilot handling. It 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. 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 Arrano has been designed with simple maintenance in mind, and components and accessories are easy to access, disassemble and exchange. Servicing time is half that of previous generation engines. Operators also benefit from new digital services from Safran Helicopter Engines, including an electronic engine logbook (BOOST) and engine-life data tracking (Health Monitoring).

Aero-engine, the well known ¡®crown jewelry¡¯, is also the cutting edge of the equipment manufacturing industry. It is estimated that in the next 10 years, China's military and civilian aviation engine market will exceed the annual average market size of more than 110 billion yuan, of which more than 80 billion are civilian markets. In the next 20 years, China's airlines will have about 4,700 new machines delivered, with a market value of more than $500 billion. The substantial increase in demand for the whole machine will definitely drive the market for engine demand. Assume that the engine price is 25% of the whole machine price, and the domestic engine market share is 40%. The domestic aircraft engine demand driven by the growth of domestic passenger aircraft in the next 20 years is 50 billion US dollars.


Under this background, 8th China Aerospace Propulsion Technology Forum 2019 on September 27th is an unmissable conference in Xi¡¯an.
