Rolls-Royce announced today that the US Federal Aviation Administration (FAA) has certified the company’s new AE 3007A1E engine variant, the powerplant for the extra long-range Embraer ERJ 145XR regional jet.

Launch customer ExpressJet Airlines, which operates as Continental Express, has ordered 104 firm and 100 option ERJ 145XR aircraft, with first delivery scheduled for later this year. The firm AE 3007A1E engine business is worth $600 million to Rolls-Royce.

The 8,110lb-thrust AE 3007A1E turbofan reportedly offers a 7 percent increase in takeoff thrust and up to a 14 percent increase in climb thrust over existing AE 3007A1 models, allowing up to a 29 percent increase in range over current ERJ 145 aircraft.

The engine is also said to offer features to increase engine durability and time between maintenance visits, including a reduced emissions combustion liner, pure airblast fuel nozzles for longer cleaning intervals, film cooled gas generator blade and vane, and cool air buffered centre sump.

The AE 3007A has nine variants with thrust ranging from 7,000lb to 9,000lb. These engines are the sole powerplants for the 37-seat ERJ 135, the 44-seat ERJ 140 and 50-seat ERJ 145 regional aircraft, the Embraer Legacy corporate jet and the Brazilian SIVAM military surveillance aircraft.
