FYI the schreckle and the like are old technology. ttere are newer and better designs. IRRC model jet engines have only been around for 30 years or so and are a developing technology.

Nice -54, Blighty!

Tin brings up a good point, there's still room for advancement in these. Before Shreckling and a couple other pioneers, it was thought to be impossible. If I understand the story correctly, these guys crunched the numbers and on paper, it SHOULD work with a 1 stage centrifugal compressor... and sure enough, it did.

There was supposed to be a master craftsman from Britain who made a PERFECT miniature of an axial flow turbojet some years ago, and the model did not sustain... the air flow doesn't scale.

Anyway, the Schreckling book is good, as is Kamps, but as Tin says, there are better designs now.
 
thx Swede......and the fact it worked was a nice suprise :)

the place to go to for turbines is www.GTBA.co.uk . the forum is full of amazing turbine home builds. not only from plans, but own designs. there's one chap who makes micro turbines (think there smaller than the Jetcat p20) so far he has got one up to 320'000 rpm and that was with a home made turbine wheel. only down side to the GTBA is it will cost you £25 for a years membership to see the forum.
