Rolls-Royce AE 2100

Rolls-Royce AE 2100 D2A


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. 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 two versions of the engine: the civil AE2100A, and the AE2100D3 military variant.

The engine uses new six-bladed Dowty propellers for use on the 50-seat Saab 2000 and the Lockheed C-130J Hercules military transport. Each engine develops 4,591 shaft horsepower.
