Description: In the 1990s, Rolls Royce and Turbomeca jointly developed the RTM322 turboshaft family to suit a wide range of commercial and military helicopter applications powered by two or three engines. The turboshaft family was designed to develop 2,100-shp at takeoff with future growth to 3,300-shp. The RTM 322 engine has been selected to power the AgustaWestland AW101, NH Industries NH90 and GKN Westland WAH-64 helicopters with approximately 1,600 engines ordered or on order. More than 900 RTM 322 engines have been produced so far, logging more than 450,000 flight hours.
The RTM 322 01/9 engine is the most powerful variant of the RTM 322 turboshaft family. It was designed to power the NH90 twin-engine helicopter. The RTM322-01/9 engine was qualified for the NH90 multi-role helicopter in October 2005 one year after its civil certification. The initial version was rated at 2,397-shp at takeoff with the potential to grow out to 2,600-shp. As of May 2005, the RTM322 engine was already selected to power the NH90 helicopters ordered by Australia, Finland, France, Germany, Greece, the Netherlands, Norway, Oman, Portugal and Sweden. This translates into 90 percent of NH90 orders to be powered by RTM322 engines.
