General-Electric GEnx turbofan engine picture label request

Click For Summary

Discussion Overview

The discussion revolves around identifying and labeling the components of the General Electric GEnx turbofan engine, specifically focusing on the internal parts visible in an image. Participants express curiosity about the complexity of the engine and seek labels for various components without needing detailed definitions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant expresses a desire for labels of all components in the GEnx engine image, indicating a lack of available resources for such detailed labeling.
  • Another participant suggests searching for labeled images of jet engines and using the thread to ask about specific parts that remain unidentified.
  • A different participant provides links to resources that may contain relevant information and discusses the concept of bypass in turbofan engines, explaining the function of the large blades.
  • A participant acknowledges their understanding of basic engine parts but seeks information on smaller, less commonly known components.
  • There is a suggestion that exhaustive searching might yield a maintenance manual, which could contain the desired information.

Areas of Agreement / Disagreement

Participants generally agree on the complexity of the engine and the challenge of finding detailed labels for its components. However, there is no consensus on the availability of such resources, and the discussion remains unresolved regarding specific labeling of internal parts.

Contextual Notes

Participants mention the difficulty in finding specific labels and the potential existence of maintenance manuals, indicating limitations in available resources for detailed engine component identification.

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!
