The Rolls-Royce AE 3007 (US military: F137) is a high-bypass turbofan engine produced by Rolls-Royce North America, sharing a common core with the Rolls-Royce T406 (AE 1107) and AE 2100.

Development[edit]

In 1988, Allison Engine (then owned by General Motors) and Rolls-Royce plc began joint studies of a 33kN (7,500 lbf) RB580 to power the proposed Short Brothers FJX regional jet, combining the T406 core with a R-R low-pressure spool. By late 1989, amid growing importance of the RR Trent and uncertainty over the Shorts project, Rolls quit and Allison pursued alone.[1]

Allison designed a new wide-chord snubberless (or clapperless) titanium fan and low-pressure turbine. In March 1990, it was selected to power the Embraer EMB-145 regional jet and for the Cessna Citation X in September 1990. Ten months after the programme launch, the GMA3007 was first ground tested in mid-1991 and fly tested on a Cessna Citation by mid-1992. In 1995, Rolls bought Allison and the engine had its first flight on the EMB-145. The Citation X 28 kN (6,300 lbf) AE3007C was certificated by the FAA in February 1995 before the EMB-145 39 kN (8,800 lbf) AE3007A in mid-1996.[1]

In 1995,the AE3007H was selected by Teledyne Ryan for the Tier II+ UAV, requiring long-endurance at up to 70,000ft (21,300m). It was tested at these altitudes in February 1996 at the Arnold Engineering Development Center in Tennessee and the first was delivered in May 1996.[1]

More than 3,400 engines have been delivered.[2] In 2014, 2,976 civil engines were installed.[3] In 2017, the AE 3007 in the ERJ family had flew over 53 million hours and over 44 million cycles.[4] It was flown for more than 60 million hours.[5]

Design[edit]

The AE 3007 is a direct drive turbofan engine with a single stage fan, a 14-stage axial compressor with 6 stages of variable vanes including inlet guide vanes, an annular combustor, a two-stage high pressure turbine and a 3-stage low pressure turbine. The accessory gearbox is mounted at its bottom and two single channel FADEC units are mounted in the aircraft. It has fore and aft mounting provisions for underwing pylon or aft fuselage installation.[6]
