O u should of added turbo fan engine to this video which just adds a large fan blade in front of this engine and a outer casing around the engine, some air goes in compressor, some goes around it in outer casing
@9743271297 Wish I could help. Although aerospace is offered at my university, I'm in mechanical engineering. I made this video to help a student with a class project. Not sure of a good book to use.
Only a small comment, the air velocity is quite constant through the compressor stages. The goal is to increase the pressure, not the speed. (To begin a preliminary design, you can start from the approximation that the inlet and outlet velocity of a given axial stage is constant)
@Aexotica Just like in cars, large turbines can have starter motors that rotate the main turbine to get things started (starts the rotation of the compressor). If it's a small engine, like for a model plane, you could even just put a fan up to it to get it started (or a hair dryer!).
@EngineeringExplained thanks you. I have a follow-up if you don't mind: by what means or mechanism is fuel provided to be ignited, does it use fuel injection?
@Aexotica In fact, as he explained, they have starters. Most are pneumatic. Air flow from the Auxiliary Power Unit is used to spool up the engine to certain RPM where fuel can be injected thus ignited andd voila! the engine has started and now works on its own. the APU is another engine used mainly as backup to power all the aircraft electric, pneumatic, hidraulic systems when the main engines are shutt off or failed.
@EngineeringExplained FYI: the Rolls-Royce RB211 is a triple spool coaxe engine. It may be the only aviation one in the world. I don't have my Encyclopedia of Turbine Engines in front of me so I can't say for sure. Babysitting at a beer buddy's house.

They have huge spark plugs lol

which book is best to understand aerodynamics, aircraft structures and jet engines.

Thank you for posting, very good

how do they get the fans to start suckin in air in the first place?

@Aexotica Yes, the fuel is sent into the combustor via fuel injectors.

Do you have a particular triple spool coaxial turbine in mind?

@TheTerribleSwede No, just using it as a demonstration to show how the different stages of the compressor rotate at different speeds.

@TheTerribleSwede Well, I'm no expert on turbine engines. Thanks for the tip; I made this video for a student who wanted help on a project.
