How jet engines work Rolls-Royce?
How does a jet engine work? The hot gases from the combustor are conveyed through a series of turbine stages. Each one of them gains energy from the steady flow of gas, rather like a windmill. This energy is primarily used to drive the fan and compressor via shafts.

What is the principle of turbofan engine?
Jet engines, which are also called gas turbines, work by sucking air into the front of the engine using a fan. From there, the engine compresses the air, mixes fuel with it, ignites the fuel/air mixture, and shoots it out the back of the engine, creating thrust.
How does a turbofan engine work?
How does a turbofan engine work? The incoming air is captured by the engine inlet. Some of the incoming air passes through the fan and continues on into the core compressor and then the burner, where it is mixed with fuel and combustion occurs. This means that a turbofan is very fuel efficient.
The rest of the incoming air passes through the fan and bypasses, or goes around the engine, just like the air through a propeller. The air that goes through the fan has a velocity that is slightly increased from free stream. So a turbofan gets some of its thrust from the core and some of its thrust from the fan.
What is a two spool engine?
As with the core compressor and turbine, some of the fan blades turn with the shaft and some blades remain stationary. The fan shaft passes through the core shaft for mechanical reasons. This type of arrangement is called a two spool engine (one “spool” for the fan, one “spool” for the core.)
Is GE the only company that makes engines?
However, GE does not only manufacture engines under its own umbrella, instead it partners with others. GE’s most successful partnership has been with Safran, creating the CFM International brand (CFM holds 39\% market share, while GE holds 16\% alone).
Which aircraft engines are made by Rolls-Royce?
Rolls-Royce British-based Rolls-Royce comes in third in this list, holding around 18\% of the engine market share. A popular brand, the manufacturer makes engines exclusively for widebody aircraft, with the A330, A340, A350, A380, 777, and 787 featuring RR engines.
