Aerospace General-Electric GEnx turbofan engine picture label request

  1. Mar 13, 2016 #1
    Hi! I am a student who is passionate about engines and mechanics (although the major I'm pursuing is CS.I believe we must not inhibit our intellectual curiosity). The following link will take you to the picture of an uncovered General Electric Next Generation Turbofan engine used by the 787 Dream liner: https://en.wikipedia.org/wiki/Gener.../File:Detail_of_GEnx_turbofan_engine_core.jpg Looking at it, I was befuddled by the complexity. I really want to know the labels of all components no matter how "high-level" they are! Defining them isn't necessary, I can search by myself. Just a label of the parts is required (simple paint edit would do!).

    Welcome to the PF.

    You should find some images of jet engines like that which do have some labels, and learn as much as you can from them first. Then after that, you can use this thread to ask about specific parts of the image that you posted which you have not been able to find information about. :smile:

    Train your search engine. It wants to please.

    Lots more here, search on keywords

    if you sent these folks a handwritten letter they'dprobably send you a sales brochure

    you do understand that modern engines (after Boeing 707) affix a shrouded propeller to the front of the engine. That's the big blades on right side of your picture.
    The turbine engine makes so much shaft horsepower that it can move lots more air than is practical to move through its internal burners .
    So most of it is directed around the engine itself, they call that Bypassing. You picked a high bypass engine.
    Those big blades out front resemble a fan, hence the name "Turbofan". They're a lot more quiet than pure jets.

    The internal losses from compressing and churning the air on its way through exceeds the power of a WW2 piston engine.


    Have fun reading.

    @berkeman Thank you for the reply- you're right. But I have done many rigorous searches and still couldn't find a label of the inside "Parts". :/
    @jim hardy Thank you for the links, and the reply! :D I am cognizant of the basic "parts" such as the blade, fuel lines, turbine, compressor, spool, etc. I wanted to get deep into the manufacturing of the engine- The little tiny parts that I am unaware of: the shining "boxes" , the red "pipes", etc.

    Exhaustive searching will probably turn up a maintenance manual. I know they're out there for WW2 radial piston engines.

    Oh great idea! I on it!
