What does CFM56 stand for?
product line CFM is not an acronym, so it doesn’t stand for anything. The company (CFM), and product line (CFM56), got their names by a combination of the two parent companies’ commercial engine designations: GE’s CF6 and Snecma’s M56.

Are jet engines reliable?
Despite the tremendous engineering and tight tolerances involved in the design, a turbine/jet engine is very reliable. Turbines do not break down easily, and if they do, it is usually a supporting system that fails. A broken pump and a clogged pipe are much more likely than the turbine to malfunction.

What planes use Rolls Royce engines?
Members of the Trent engine family are now in service on the Airbus A330, A340, A350, and A380, as well as the Boeing 777 and 787 Dreamliner.
How much horsepower does a Boeing 737 have?
737 engines produce about 29,000 pounds of thrust. Boeing uses Rolls Royce engines on some of its aircraft but not the 737. B737s have various engine power ratings. The power is not expressed in horsepower but the equivalent is 40,000 to 80,000 horsepower, depnding on the dngine model.
What does Snecma stand for?

Does Airbus use GE engines?
Further, GE supplies engines for Airbus’ A330 family of aircraft. On Airbus’ A380 family of superjumbo aircraft, the company offers products build by Engine Alliance in which GE owns a 50% stake [xvi].
What kind of engine does the CFM56-3 have?
The CFM56-3 is a high bypass, dual rotor, axial flow turbofan engine. Basic engine specification are provided in Fig 1 and 2. The integrated fan and booster (low pressure turbine-LPC) is driven by a 4 stage low pressure turbine (LPT). A single stage high pressure turbine (HPT) drives the 9 stage high pressure compressor (HPC)
How many flight hours does a CFM56 engine have?
Operational history. As of June 2016, the CFM56 is the most used high bypass turbofan, it achieved more than 800 million engine flight hours, and at a rate of one million flight hours every eight days it will achieve one billion flight hours by 2020.
How do thrust reversers work on CFM56 engines?
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.
What is the by-pass ratio of the CFM56-3?
At static take-off power, the CFM56-3 has a by- pass ratio of 6:1. This means that there is six times more secondary airflow than primary. The equation for by-pass ratio is shown below.
