Hmmm I was thinking along these lines only the other day.
If it's carefully designed it should be able to provide a lot more than 15% extra thrust
The Russians made an early jet fighter that used a piston engine to drive the compressor and a combustion chamber like a conventional jet engine. The idea has a few advantages over the traditional gas turbine design, especially in model size applications. properly designed it should over double the thrust but you wouldn't use it as an afterburner it would have to have a proper combustion chamber and nozzle and would have to burn fuel all the time.

Yes indeed mate - the best episode of Flitetest I've ever seen

Hey Jason,
Yeah I think the concept is a thermojet, pretty inefficient but when you want a boost in combat it was a good stopgap.
I suppose the limitations we have are the materials, pressure and temperature are not good friends of EPO.
He certainly had his hands full! I was pleased to hear him saying they were working on retract selection because a beautiful model like that cries out for them.
Andrew, You Inspiring me to finish off my Viper Jet

Just to get this thread back on track
Here's an interesting link I found discussing various experiments with motor Jets.
It's also interesting to note that some people are using EDF set ups to supercharge internal combustion engines.
OK Jason you have my attention... I'm interested ... what Link????
