Small turbines for homebuilts?

The top model gives 51,7 pounds of thrust.
I've seen many of them "At work" on RC models. Amazing.

They spec 10.5 gal/hour for 52 lb thrust (51.7 actually). Which is close to
what the other 30 /b unit spec'ed
John

They spec 10.5 gal/hour for...

Correct.
The good thing about AMT is the MTBF, which is considerably longer.

This, mounted on a real aircraft instead of a RC model, can be quite
reassuring.

Did you see the skydiver with a wingsuit with 2 jets strapped to his boots?

Too cool !!!

Did you hear him say that he was able to maintain level flight for half a
minute, until his tanks went dry? That is what I think he said.

Lets see, what if you put 6 or 8 of those 50 pound thrust units in a jetpack
type of arrangement. You should be able to maintain level hovering flight,
right? Fuel demands would mean that you could not hover for very long, but
it would be much longer than the current jet packs in use, right?

You know, if I had enough money, I might just take that project on!

Damn, Jim. I'd spend a buck to watch!

there are "scratch designed & built" 150 hp-equivalent turboprop engines on the market - check out www.innodyn.com - they flew to oshkosh with a turbine equipped super cub ( http://www.innodyn.com/aviation/news..._05_05_01.html ). furthermore, they claim to burn only slightly more than a piston engine, which i find remarkable. they say they have a twinpac planned which would output 300 hp.

If you read more carefully, Innodyne is taking existing turbines and adding
their fuel control system. Also, given the consensus that a turbine simply
can't offer the specific fuel consumption (or even close) to a recip, their
data on fuel consumption (or rather, the lack of hard data) seems suspicious
to me.

Innodyne has been in this game for years and to the best of my knowledge
have never delivered a single customer engine. I'd stay away until they
have a track record and can provide substantial independant confirmation of
their fuel consumption claims.

You mean something like this?
