Turbomeca has received EASA type-certification for its Ariel 2N turboshaft engine, the newest addition to the Arriel 2+ family. The engine first ran in September of 2011, and it offers lower operating costs along with increased reliability and performance compared to its predecessors. It features a new axial compressor, new high-pressure compressor diffuser, new high-pressure turbine material and new-generation dual-channel Fadec. Because of these features, the Arriel 2N delivers 17 percent more take-off power than the current Arriel 2C (986 shp/735kW compared to 840shp/626kW).

The engine also includes a new engine data recorder and a turbine blade-creep monitor that allows the user to focus more on preventative maintenance than traditional maintenance. These features reduce unscheduled removals, improve airframe availability and contribute to a time between overhaul (TBO) of up to 4,000 hours.
Airbus Helicopters has selected the Arriel 2N for the AS565 MBe “Panther,” the naval version of the Panther family of helicopters. The all-weather, multi-role light helicopter can be operated from ship decks or offshore to cover a vast array of naval missions such as maritime surveillance, search and rescue (SAR), casualty evacuation, vertical replenishment, offshore patrolling and counter-terrorism. It is ideal for anti-submarine warfare (ASW) and anti-surface warfare (ASuW) tasks, such as submarine and surface target destruction.
