Arriel Print E-mail

Turbomeca has produced over 8,200 Arriel turboshaft engines to date, logging more than 27 million hours in flight with over 1,300 customers in 110 countries.

Since its launch in 1977, there have been 28 different versions of the Arriel, powering 28 different light and medium helicopter types. Today, there are two basic variants in Turbomeca's Arriel family: Arriel 1 and Arriel 2. Takeoff power ranges from 478 kW (640 shaft horsepower) to 704 kW (944 shp).

The 6,000th Arriel was delivered in 2005. New versions are currently being developed with production and sales still on the rise. This figure represents a unique success story in the industry, boosting the Arriel to the position of world leader in its category. Two new versions, the Arriel 2C2 and the Arriel 2S2 have been developed, respectively for the Eurocopter EC 155 B and the Sikorsky S-76 C++.

The 28 Arriel versions power modern helicopters like the Eurocopter Ecureuil, Dauphin, EC130, EC145 and EC155, the Sikorsky S-76 and the Agusta A109 K2. The Arriel has long proven its reliability in a wide variety of demanding missions, including EMS, SAR, utility and offshore operations.

Turbomeca has also achieved a major breakthrough into the Chinese market with the Arriel 2C on the H 410 A. The H 410 A completed its maiden flight in September 2001 and is CAAC-certified. In 2004, the USCG (United States Coast Guard) selected the Arriel 2C2 CG engine for the re-engining of the 95 HH65 Dolphin helicopters. In 2010, the same engine was selected for the 34 upgraded AS365K Panther of the Brazilian Army. In 2006, EADS North America was awarded the United States Army’s Light Utility Helicopter contract, including 322 UH72A Lakota twin-engine helicopters powered by Turbomeca’s Arriel 1E2.
