Rolls-Royce / Turbomeca RTM322
The RTM322 is a shaft turbine engine from Rolls-Royce Turbomeca Ltd. (a joint venture between Rolls-Royce and Turbomeca ). It was designed as a drive for various helicopters , but can also be used to drive ships and machines.
description
The engine is designed as a two-shaft engine, with a two-stage low - pressure turbine driving the output shaft and a two-stage high-pressure turbine driving a three-stage high-pressure compressor and also a single-stage centrifugal high-pressure compressor. The newer versions are equipped with a two-channel FADEC system.
history
The first order was placed in 1992 by the Royal Navy , in which it is used as a drive in 44 EH101 Merlin HM1s from 1998 . In the meantime, more than 700 RTM322s have been delivered (as of 2006).
On April 23, 2013, Rolls-Royce announced that it would withdraw from the RRTM joint venture. The 50% stake will be bought by Turbomeca. The preliminary contract was signed on April 22nd.
