Rolls-Royce AE 3007

The Rolls-Royce AE 3007, designated F137 by the US military, is a turbofan engine produced by Rolls-Royce North America at Indianapolis. It was developed by the Allison Engine Company, which is the origin of the AE in its name, and it shares a common core with the T406 turboshaft and the AE 2100 turboprop. The engine has a single-stage fan, a 14-stage axial compressor, an annular combustor, a two-stage high-pressure turbine and a three-stage low-pressure turbine. It was first ground tested in mid-1991, was selected for the Embraer EMB-145 regional jet and the Cessna Citation X, and Rolls-Royce bought Allison in 1995. More than 3,400 engines have been delivered, and variants include the AE 3007H for the Global Hawk and Triton and the AE 3007N for the MQ-25 Stingray.
