Description: The Turbomeca Arriel engine family was designed very simple with reduced parts and only five modules for ease of maintenance while delivering excellent handling characteristics and high level of reliability. Arriel 1-series have been installed on a wide range of twin-engine commercial/military helicopters. Arriel 2 is an improved variant with the gas generator turbine made in one stage with single crystal blades compared to Arriel 1. The engine is controlled by a single channel electronic control unit with manual backup. The Arriel 2 engines are used to power lightweight helicopters. Launched in 1977, Turbomeca has produced more than 10,000 engines logging more than 32 million flight hours with 1,300 customers in 110 countries.
The Turbomeca Arriel 2D engine is fitted with a new generation of digital FADEC (Full Authority Digital Engine Control) and a data recorder for condition monitoring. It is intended to power the Eurocopter AS350 B3e single-engine helicopter. Turbomeca and Eurocopter will certificate the new aircraft along with the Arriel 2D in the summer of 2011 with the first AS350 B3e delivered to the launch customer before the end of 2011. The engine was selected to power the Eurocopter EC130 T2 helicopter beginning in 2012.
