The Safran Arrano is a turboshaft engine for two-to-three ton single-engine and four-to-six ton twin-engine helicopters, developed by Safran Helicopter Engines, outputting 1,100 to 1,300 hp (820 to 970 kW). It should reduce brake specific fuel consumption by 10 to 15 % compared to previous engines, contribute to increase new helicopters payload-range performance, with reduced size and is designed to facilitate maintenance and repairs. First bench tested in February 2014 in Bordes, Pyrénées-Atlantiques, its thermodynamic core comes from the Clean Sky Tech 800 demonstrator, first tested in April 2013. In cruise, its thermodynamic cycle is improved by variable-pitch Inlet Guide Vane blades above the compressor. Metal laser sintering is used for serial production of the combustion chambers injectors.[1]
It powers the Airbus Helicopters H160 which made its maiden flight in Marignane on 27 January 2016.[2] Since January 2016, it has amassed 4,000h of testing and 700h of flight time, the first production units should be delivered in early 2018 and the H160 should enter service in 2019. It passed blade-out tests, continued operation with no lubrication, altitude trials in 2016 in Saclay and in 2017 endurance should be tested in all operating conditions for certification.[3]
