Turbomeca Arriel 2N Turboshaft Granted EASA Type-Certification
The newest addition to the Turbomeca (Safran) Arrien 2+ family, the Arriel 2N Turboshaft, has received EASA type-certification. The engine first ran in September 2011, and offers low operating costs, increased reliability and superior performance.
“The certification of the Arriel 2N in December 2014 has roused a clear interest in the airframer community,” Jean-François Sauer, vice president for the Arriel and Arrius programs, told Rotor & Wing. “We have entered into a few competitions for which a derivative of the Arriel 2N is being proposed. I am very confident that the 2N model will encounter more success in the future.”

The Arriel 2N turboshaft 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 takeoff power than the current Arriel 2C (986 shp/735kW compared to 840shp/626kW). The Arriel 2N also has a 30-minute takeoff power rating for the most demanding missions.
Airbus Helicopters has selected the engine to power the new AS565 airframe, the AS565 MBe Panther, which is the naval version of the Panther family.
“AS565 MBe ‘Panther’ is the new AS565 model, “said Sauer. “As the previous AS565 was powered with Arriel 2C engines, Airbus Helicopters has renewed its confidence in Turbomeca for this upgraded model.”
The all-weather, multi-role light helicopter can be operated from ship decks or offshore to cover a vast array of naval missions including maritime surveillance, search and rescue (SAR), casualty evacuation, vertical replenishment, offshore patrolling and counter-terrorism, and is ideal for anti-submarine warfare (ASW) and anti-surface warfare (ASuW) tasks, such as submarine and surface target destruction.
