Model Turbine engines have a long way to go before they reach the level of perfomance that can and has already been achieved in 4'' diameter sizes. I have seen compression ratios of 6:1 and 300N thrust at FSC of 0.02 g/N/s in KJ sized package, using ceramic NGV and turbine, 600N with 2000 deg EGT.
Mainly the compressors and diffusors are radically different from the current CFD ''optimised'' designs. Combustors are simple but also very different.

Will this technology make its way into model turbines and at what price?
