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...

What exactly is a centrifgual compressor?

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

I didn't know that such a thing existed.

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.

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...

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..
