The Arriel 2 turboshaft engine features a very simple design, with a reduced number of parts and only five modules for easy maintenance. It capitalizes on the experience and know-how gained with the Arriel 1 family. The Arriel 2 has a TBO (Time Between Overhaul) of 3,500 hours.

The Arriel 2B powers the single-engine Eurocopter AS 350 B3 Ecureuil, capable of carrying 6 passengers. This helicopter is designed to operate under high altitude and hot temperature conditions.

The Arriel 2B1 powers the latest member of the Eurocopter family, the single-engine EC 130 B4. This new helicopter can seat 6 or 7 passengers. It features a dual-channel Electronic Engine Control Unit (EECU) with manual backup.

In september 2011, Turbomeca signed a new cooperation agreement on Arriel 2B1A with SAIC (South Aero-engine Industry Corporation) and AVIC International (AVIC International Holding Corporation), to power notably the AC311. The engines deliveries are scheduled in the course of 2012.
