The CFE CFE738 is a small turbofan engine aimed at the business/commuter jet market manufactured by the CFE Company, and is used on the Dassault Falcon 2000. Design and development [ edit ]
The GE Passport is a high bypass ratio turbofan. The engine is a twin-spool, axial-flow turbofan with a high bypass ratio of 5.6:1 and an overall pressure ratio of 45:1. The front fan is attached to the three-stage low-pressure compressor; the 23:1 pressure ratio 10-stage high-pressure compressor includes five blisk stages for weight reduction.
More than 3,400 engines have been delivered. [5] In 2014, 2,976 civil engines were installed. [6] In 2017, the AE 3007 in the ERJ family had flown over 53 million hours and over 44 million cycles. [7] It was flown for more than 60 million hours. [8] The engine is manufactured at the Rolls-Royce North America engine plant in Indianapolis ...
The American Federal Aviation Administration certified the engine for commercial operation on January 4, 2006. [4] The engine was ground run for the first time on an A380 on August 14, 2006, in Toulouse. [5] On August 25, 2006, the same aircraft, A380-861 test aircraft (MSN 009), made the first flight of an Engine Alliance powered A380.
The engine's name is a combination of the Roman numeral V, symbolizing the five original members of the International Aero Engines consortium, formed in 1983 to produce the engine, and 2500, which represents the 25,000-pound-force (110 kN) thrust produced by the original engine model, the V2500-A1.
The engine has two contra-rotating rotors (fans) on the outside of the engine nacelle, either at the front of the assembly ("tractor") or at the rear ("pusher"). Both pusher and tractor open rotor designs form part of Rolls-Royce's long-term "15-50" vision, which is examining various architectures to tackle the 150 seat-aircraft market.
The Trent 900 is an axial flow, high bypass turbofan with the three coaxial shafts of the Rolls-Royce Trent family. The 2.95 m (116 in) fan with swept blades is driven by a 5-stage LP turbine, the 8-stage IP compressor and the 6-stage HP compressor are both powered by a single stage turbine, with the HP spool rotating in the opposite direction of the others.
The swept fan blades produce 2–3% more flow at a given speed with the same 2.8 m (110 in) fan, for an additional 10,000 lbf (44 kN) of thrust, while fan efficiency is 1% better.
