it works by how the pilot operates it. Engine start on the top of the head location. the pilot pulls the switch down know as engine ignition. It would start the turbofan and it would be blowing fast
That is completely wrong!! Whoever wrote the above knows nothing about Aerospace Engineering and needs to find something different to do in their lives. The Turbofan jet engine is the most commonly used engine on a commercial airliner such as a Boeing 747 or a 737. Basically an enormous fan sucks in lots of air, which is then separated into two groups: around 80% goes into the bypass duct, and stays cool, while the small amount that remains goes through the core. In the core, the air is pressurized first in the Low Level Compressor, then pressurized even more in the High Level Compressor. This extremely pressurized air is then forced through the Combustor, where fuel is injected into it and then ignited. This creates very hot air, and is forced through a series of Turbines. After this, the cool air from the bypass duct is mixed with the hot air from the core and is forced out of the Nozzle in an hourglass shape to create thrust. This is exactly how a Turbofan Engine works.
A turbofan is an Cold Air Unit that lowers the temperature of the air passing through it. The air is made to work (reducing temperature) by turning the turbine and made to work even more (another drop in temperature) by turning the fan.
turbine as it is ; is used for power production mechanically or electrically.
gas turbines are turbines which run on high temperature high pressure gases expanding through them. the gases usually are helium and carbon di oxide.

Look up the Bloodhound SSC, they've put the Eurojet EJ200 turbofan engine from the Eurofighter Typhoon into it to break the land speed record.

An aircraft uses a turbofan engine to reach takeoff and cruising speed. Look up TURBOFAN on Google for more info!
High Bypass turbofan engines use pneumatics (air) for starting the engines.
Piston, turbojet, turbofan, turboprop to name a few.
A propeller is completely external and is the main source of propulsion for a airplane with a piston or turbojet engine. A turbofan is more enclosed and provides some propulsion along with also cooling the jet engine that is the main source of propulsion.

Thrust, typically created by a propeller attached to an internal combustion or turbine engine, or by a turbofan.

The term "Turbofan" is actually quite broad, but can be broken down into two categories…high and low bypass. The question you are really trying to ask is which engine type (high bypass or low bypass) turbofan engine is more efficient? High bypass engines are used on most commercial airplanes (except the Concord) and these engines are favorable because they have a balance of high thrust, and efficiency. Aircraft that need supersonic capabilities (like the Concord) use a low bypass turbofan engine. These engines produce the thrust required to propel a plane beyond the speed of sound, but at the cost of efficiency. They burn a lot of fuel in doing so. So one could draw the conclusion that high bypass turbofan engines are more efficient, but this would not be true. In order to propel a plane beyond the speed of sound the low bypass turbofan engine is the most efficient way of doing so. On the flipside, the high bypass turbofan engine is most efficient for practical air travel. Both engine types are very different, but each are specialized to achieve different goals.
