RC Model Turbo-fans

Take a look at the Gas Turbine Builders site: gtba.co.uk
Plenty of information there.

Interesting to see what looks like a homebuilt high bypass fan!

Ah, ok, thanks for that. I knew jet engines were around for models e.g. the model A380’s, but I just assumed they would be axial turbo-fans also – of course on a much simpler scale!

Hello all. A regular in Commercial, but have a question for here.

I am looking for ideas for a final year project and am interested in using my ‘knowledge’ of jet engines. My question is: how accurate are scale turbo-fans currently available for RC models. Namely, are their general operating efficiencies comparable to commercial engines and how complex are their workings (comp/turb stages etc).

Any information on them would be much appreciated.

Thanks, Symon

I admit to not knowing a great deal about this but it was my understanding that some (if not all) turbine engines for R/C models are centrifugal flow turbojets, so slightly older technology than the now-standard axial flow full size units.
