Not that I know (because I don't know), but it doesn't make sense
that titanium would be an unsuitable material. Gas turbines using
titanium alloy compressors have been around for, well, decades. Sort
of an apples and oranges comparison, but still...


Two big differences, as I see it. One, props on piston engines receive
massive power pulses, which are almost like stop and go, every 1/3rd to 1/2
rotation. A gas turbine blade has no pulses going to it; constant power and
constant rotation. Two, the turbine blade is very short and wide, compared
to the long slender prop.
