Mechanical parts of a jet engine

Click For Summary

Discussion Overview

The discussion revolves around the mechanical components of jet engines, focusing on topics such as mechanical efficiency, blade rotation, inertia forces, and the comparison of different types of jet engines. Participants are exploring what specific mechanical aspects to include in a project and seeking guidance on relevant formulas and information.

Discussion Character

  • Homework-related
  • Exploratory
  • Technical explanation

Main Points Raised

  • Max expresses interest in writing about mechanical efficiency and the rotation of blades in jet engines.
  • Max mentions the possibility of calculating speed and discussing inertia forces.
  • Some participants suggest that fluid dynamics may be a significant mechanical aspect of jet engine operation.
  • A participant questions the relevance of "mechanical efficiency" and proposes exploring the optimum number of blades per turbine and the differences between turbojets and ramjets.
  • Max acknowledges the complexity of the information available and seeks more concrete details rather than extensive documents.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specific mechanical topics to focus on, and there are differing views on the relevance of certain concepts like mechanical efficiency. The discussion remains exploratory with multiple perspectives presented.

Contextual Notes

There are limitations in the clarity of definitions and the applicability of certain concepts, such as mechanical versus thermal efficiency, which remain unresolved. Participants express uncertainty about the best approach to gather useful information for the project.

Hi guys
I'm making a project about jet engine.
I need to write 10 pages of the mechanical part of a jet engine.
I already did it for physics.
What can i talk about. I need formules en stuff in the 10 pages
Ty for the help guys!
Max
 
Physics news on Phys.org
What have you found out for yourself so far ?

Please use some recognisable language when replying .

Yes sorry for the language I am not a native English speaker but i will do my best.
I think I can write something about the mechanical efficiency of the engine.
Also about the rotation of the blades.
Maybe i can do something how to calculate the speed..
I can do something about the inertia force ( traagheidskracht in dutch).
I don't know if i can get good information of this things.
Maybe you have something in mind with good information?

yes I already had that but its a little useless to me when i don't know what to use.
you know i didn't ask for helping me write jet engine pdf on google...

Well, it seems like the PDF that was posted in reply to your question was pretty much on-topic. Do you want us to do your homework for you?

Can you expand on your thoughts above? "Mechanical efficience" wouldn't seem to apply, but fluid dynamics would seem to be a big "mechanical" part of a jet engine's operation...
 
Idk man but i thought you guys could give me more concrete stuff than 300 pages.
But np
Thanks for the help man
and the mechanical efficiency. i might be wrong but i thought there was the thermal efficiency and the mechanical efficiency.

Mechanically/aerodynamically what determines the optimum number of blades per turbine? What determines the optimum number of turbine stages? Compare and contrast a turbojet with a ramjet mechanically... Why are they different?

That should get you to 10 pages easy! (and be pretty interesting as well) Have fun! :smile:
