Next step will be a test bench for the turbine (measure the torque at 60'000 rpm's and 50 kW shaft power
isn't trivial... but feasible).
That's a mere 8 Nm of torque.
Simple to measure.
In theory :-) :-) :-)
Measure the torque is the easy part, indeed.
Not so easy is to get rid of the 50kW from a *fast* spinning shaft. To characterise the turbine you need some kind of an adjustable load, typical a eddy current brake or fluidic brake. An eddy current brake has to be cooled, so we have chosen a fluidic brake... the fluid is also the coolant then. But the rotor, bearings, joints has to withstand the 50'000 rpm's ... we will probably learn some good lessons which we can use for the pump part later.
