Where does the CFM International CFM56 engine come from?
CFM International CFM56. GE produces the high-pressure compressor, combustor, and high-pressure turbine, Snecma manufactures the fan, gearbox, exhaust and the low-pressure turbine, and some components are made by Avio of Italy. The engines are assembled by GE in Evendale, Ohio, and by Snecma in Villaroche, France.
What is the compression ratio of a CFM56-3 turbofan engine?
The smaller size also allows more space for the variable stator vane assembly which are configured across the first 4 stages of the HPC shown in Figure 9. The overall compression ratio () of the CFM56-3 is 27.5:1. The components of the HPC consists of: 1. The compressor rotor 2. The compressor front stator 3.
How does the reverse thrust on a CFM56 engine work?
The CFM56 also supports pivoting-door type thrust reversers. This type is used on the CFM56-5 engines that power many Airbus aircraft. They work by actuating a door that pivots down into the bypass duct, both blocking the bypass air and deflecting the flow outward, creating the reverse thrust.
Which is the CFM56 engine for the A320?
The CFM56-5B is the engine of choice for the A320 family, having been selected to power nearly 60 percent of the aircraft ordered. Today, it is the only engine that can power every model of the A320 family with one bill of materials.
What are the specific operating instructions for CFM56-3?
The following extracts are from the CFM56-3 Specific Operating Instructions manual, courtesy of Capt Selva Kumar. All of the information, photographs & schematics from this website and much more is now available in a 374 page printed book or in electronic format. The CFM56-3 is a high bypass, dual rotor, axial flow turbofan engine.
How tall is the CFM International CFM56-3 training manual?

How does the CFM56 high pressure turbine work?
All variants of the CFM56 feature a single-stage high-pressure turbine (HPT). In some variants, the HPT blades are “grown” from a single crystal superalloy, giving them high strength and creep resistance.
