History
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).
Development
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. It powers the Airbus Helicopters H160 which made its maiden flight in Marignane on 27 January 2016.
By October 2017, 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. By October 2018, the programme had accumulated 7,500h, including 1,500h of flight time, certification testing was close to the end and most of the documentation should be submitted by the end of the year.
The turboshaft received its type certificate during the June 2019 Paris Air Show, before EASA approval for the H160 planned for the fourth quarter and first delivery to a US customer for corporate transport in May 2020
