Rolls-Royce will provide the US Air Force and US Marine Corps with more than 240 AE 2100 engines for C-130J transport planes under a contract awarded by Lockheed Martin.
The six-year agreement covers the supply of engines, spares and other services and is valued in excess of $300 million.
The US Air Force currently has an order for 40 CC-130Js, the stretched fuselage version of the C-130J whilst the US Marines Corps has 20 KC-130J air refuelling tankers on order.
The AE 2100, a turboprop derivative of the AE 1107 turboshaft engine, was developed to power the new generation of high-speed regional aircraft, military transports and long-range maritime patrol aircraft. Operators reportedly benefit from 80% parts commonality among the AE common core engine family, which includes the AE3007 turbofan.
The AE 2100 turboprop is a two-shaft design with a 14-stage compressor driven by a two-stage HP turbine. The two- stage LP turbine drives the compound planetary reduction gearbox.
The engine is said to be the first to use dual FADECs (full authority digital engine control) to control and monitor both the engine and propeller.
‘Rolls-Royce is the world leader in military turboprop transport propulsion,’ said Steven F. Dwyer, President, Defence North America, Rolls- Royce. ‘The outstanding capabilities of the C-130J aircraft coupled with the proven performance of the Rolls-Royce AE 2100D engine will give the US Air Force and US Marines Corps strategic range on a powerful tactical airlifter.’
