Rolls-Royce Plc
: 03 May, 2010  (Application Story)
Ship to Shore Connector vehicle for use by the US Navy gains benefit from the MT7 engine from Rolls-Royce based on the AE 1107 turboshaft unit
Rolls-Royce has announced that the principle application of the MT7 marine engine is the US navy ship to Shore Connector air cushion vehicle program, which requires a lightweight and robust engine. The MT7 is a variant of the combat-proven AE 1107 turboshaft which powers the US Marine Corps and Air Force V-22 aircraft.

In addition to offering an exceptional power-to-weight ratio, the MT7, through its heritage, is demonstrating excellent resistance to challenging environments, ranging from shipboard to desert operations. This experience allows the MT7 to deliver benefits to its users through extended engine overhaul intervals and lower total ownership costs.

Andy Marsh, President Rolls-Royce Naval Marine, said: 'The MT7 is a fine example of how Rolls-Royce invests in core technologies that can be used multiple times across a family of engines and applications. Just as the MT30 was qualified to naval requirements for the LCS and DDG 1000 programs, we expect the MT7 to be equally successful. The MT7 is an important step forward for the naval business and broadens our product offering to meet emerging customer needs, especially for the Ship to Shore Connector program.”

The company’s common core engine family includes the AE 1107 turboshaft, the AE 2100 turboprop and the AE 3007 turbofan. With over 40 million flight hours accumulated on more than a dozen different applications, the AE engine family provides many advantages for the MT7 program. The common core architecture also allows the MT7 to benefit from an active, well established supply chain, and cost effective production, repair and overhaul processes.

Approximately 400 MT7 engines have already been delivered, with 1000 additional engines scheduled for delivery. MT7 production takes place in Indianapolis, Indiana.
