The turbines that we run are single stage (compressor & turbine) turbojet engines. Typically the compressor is an off the shelf commercial centrifugal compressor wheel, like that of an automotive turbo charger. The turbine wheels are expensive cause they are custom cast from Inconel and are of the axial flow type. The engines typically run from $2500 to $4500. EGT (Exhaust Gas Temp) runs about 650 degrees C at full throttle. We normally run Jet A (kerosene) for fuel mixed with about 5% turbine oil for bearing lubrication.
