Rolls-Royce AE 2100

The Rolls-Royce AE 2100 is a turboprop developed by Allison Engine Company, now part of Rolls-Royce North America. A derivative of the Allison AE 1107C-Liberty (Rolls-Royce T406) turboshaft engine, the AE 2100 shares the same high-pressure core as that engine, as does the Rolls-Royce AE 3007 turbofan. The engine is a two-shaft design, and was the first to use dual FADECs (full authority digital engine control) to control both engine and propeller. There are four variants of the engine: the civil AE 2100A, and the military variants which include the AE 2100D2/D2A, AE 2100D3, AE 2100J and AE 2100P.
