Which books/courses do I need to build a miniature jet engine from scratch
As a hobby I would like to build mini planes that can fly. The first step would be to understand how to build a jet engine. I know a lot of physics is involved in building one. is there a course or a series of books that would teach me the how to build a jet engine from scratch
"mini planes that fly"... that doesn't require a jet engine, and certainly not one built from scratch.
As many have already mentioned, building a jet engine from scratch isn't exactly easy or cheap. In your position I would get a battery, electric motors, propeller, microcontroller and a 3D printer, then figure it out from there.
I know it's probably a bit off from what you wanted, but it's a "cost efficient" way to actually built something. Once you have something flying you can upgrade from there...
I am currently in the process of building my own drone from scratch this way, designing the drone and programming the remote control, flight controller completely myself... it is/was a lot harder than I expected. So, what I am trying to say is: don't be afraid to use of the shelf components and don't make things harder than they have to be. Get started, then get creative.
Just my experience with this.
This is not my area of expertise, but I'd think that starting with a jet engine is not the "first step". Wouldn't making an ultralight, or even just a glider be first? Make sure your creation fly... then give them lots of power?
Famously, in recent history:

To build a jet engine from scratch you would need a $50000 machine tool shop and several years of prior experience.
I agree that it would be difficult to build a turbojet engine completely from scratch --- that is, you build every single component yourself --- but you can take some off-the-shelf components and hack together a working jet engine if you know what you are doing and get all of the right parts [1]. It won't be pretty or efficient, but it could work.
Alternatively, if you really do want to build a "jet engine" from scratch, consider building a pulse jet engine [2]. You might be able build one with parts from a home improvement store over a long weekend. It won't be a great engine, but it might be possible.

My first stop for building anything is YouTube.

IANAAE (Aerospace Engineer), but...
- Is your government okay (both in theory and practice) with you building such a thing?
- How high-performance do you want it to be?
- What's your budget, both time and money?
1) government of india i believe would have no issues 2) define high performance 3) i am honestly not aware of what goes into building a jet engine (even a mini one) so not sure how much it would cost, how about we take a number 300$ and work from there for the time being
You have to define what you mean by "jet engine."
A gas turbine? Solid fuel (like a bottle rocket?) Liquid fuel?
i am assuming a very small one can be powered by a battery, slightly bigger ones might need diesel i guess or does it have to be aviation fuel all the time?
Sorry but
> I know a lot of physics is involved in building one.
+ your comment here makes me think you have a lot of research to do.
You should focus on getting an off the shelf propeller based remote controlled plane if your budget is also only $300 and not $3000+

Sorry what? Why would your first step in building planes be to build a jet engine? That's crazy.
If you want to build a jet engine then go for it, but if you really just want to build planes then you can buy electric/piston/jet/rocket engines for much less than it would cost to build your own.
