Tiny turbos? Answered

Hey I was wondering if anyone had any idea if there are tiny turbos out there, One's that could be used in a jet engine.

You see my [https://www.instructables.com/id/The-accidental-pocket-jet-engine.../ jet engine] doesn't generate thrust in any real quantity but I had a great idea for a design that would be tiny and possibly capable of being used in some more interesting projects, only I need a turbo of some sort...

It's a pulse jet though, if it's the one I'm thinking of, I have a plan for a turbo jet, basically it needs to be small though, preferably two of them. As J-tobako sent me to a site where I found RC jet planes I dug around for homemades and found a few one of which develops 110lbs of thrust and was made with a drill and lathe...

Sure I'll try and find it again, I did a few hours of searching through the web so specifics are eluding me right now... I actually just had another mental breakthrough that might make the whole thing much easier and better aswell, a bit of new tech for instructables if it works... *runs to lair and plans insane ideas*

Well don't waste your time looking for a link, I just thought that you might have had it Favorited(?) or bookmarked. Just keep brainstorming.

If I found a really small centrifgual compressor I could work with parts from them...

It's a turbine based compressor rather than a piston based design. I wonder if a roots type blower could work here...

What if instead of trying to find a turbo small enough to fit inside you put two metal bladed fans on the outside of it? (one on each side.)

I may have a solution, though it is electronic. The picture I attached is of a small computer fan that sucks air in through a hole like a normal fan, but blows the air out of the rectangular opening pictured. You could make an attachment to the rectangular output and use that as a turbocharger.

Not really what I'm looking for but it does give me a few ideas...

How tiny? There's a 4" dia, 8" long one for about $4k (mercury airstart, electric start adds about 4"). I've heard that M-DOT had a 1.75" x 2.5" with 1-1.5 pounds of thrust, but couldn't get a current price or availability.

I've seen some backyard ones that started with car parts, biggest problem was the 110 decibel exhaust.

I suspect building my own out of homemade parts and scavenged parts is the most likely plan, after having a better dig on the googlenet I found a few homemade's made with a drill and a lathe, a few involved welding. i think the best plan is to make an axial flow compressor for it and see how well single stage compression works, if it goes well then add a second turbine. Until then the only thing I can use to add power to the existing engine is an afterburner, you never know that might be enough to achieve thrust...

oh I had read that before, Some of my ideas are based on this, granted mine is much smaller so the tiny turbos are needed.

breaks into song: "tiny turbos....." oh wait, Don Ho sang tiny bubbles.....*blush* I understand, I wasn't sure if you had seen that or not. I hadn't had time to read through it myself yet.

Ah that and one of our marching songs tiny bobbles, tiny bobbles, in my ______ then the funny bit comes to the same tune. One memorable quote was tiny bobble in my ****, Whats that smell, it's the english up front. Specific to a day involving them, it was greatly amusing for everyone when they attempted comebacks..
