You know, you might think about a 'tesla turbine' for that - it's much more efficient and can be made from ceramics so would be very heat tolerant.


Calculate this approximation derived from flywheel physics:

s=(d*tv^2)/(4*pi^2)

where
s = tensile strength of the tesla turbine disk material
d = density of the tesla turbine disk material
tv = tangential velocity of the tesla turbine disk

You'll quickly realize that the exhaust velocities of rocket engines require unobtanium for tesla turbines or any kind of turbines.
