Turbomeca (Safran) is bringing two members of its medium-heavy engine range – the Makila 2 (1,800 – 2,100shp) and the RTM322 (2,100 – 2,600shp) – to next week’s Farnborough Air Show (July 14-20).

Over 2,200 engines have been produced, so far generating ten million flight hours for 90 customers in 50 countries.
The latest variant of the Makila, the 2B, is under development to power the EC225e. It features a new combustion chamber and high-power turbine blades provide up to seven per cent more power; thus delivering considerable payload and range improvements. Certification is planned for 2015.
The RTM322, is designed and certified for both civil and military helicopters. It currently powers the three-engine Agusta Westland AW101 Merlin and MCH101, as well as the twin-engine NH 90 and WAH64 Apache. This engine also staked a place in aviation history by setting a new world speed record of 255 knots, while installed in the Airbus Helicopters twin-engine X3 hybrid rotorcraft.

Certification of the 2B2 Plus is anticipated later this year. Other member of the Arrius family, the Arrius 2R to power the Bell 505 Jet Ranger X with first flight planned by the end of 2014.
