With the compressor blades on a gas turbine, could the low pressure blades be made of aluminum, or would it be catastrophic?

Edit: Like the 6061 alloy.

  • $\begingroup$ If your turbine operates on steam or compressed air then I think it's feasible. But if you mean hot combustion gas at 1000+K temperature, then it would be very very hard. $\endgroup$ – user3528438 May 3 '17 at 18:01
  • $\begingroup$ You should be more specific. Which gas turbine? $\endgroup$ – Manu H May 8 '17 at 7:12
  • $\begingroup$ @ManuH any? It's kind of a generalized qeustion $\endgroup$ – Lilrags16 May 8 '17 at 13:06
  • $\begingroup$ @Lilrags16 You may precise it in the question, and there is a chance the question will be closed as too broad. $\endgroup$ – Manu H May 11 '17 at 7:41

The answer is yes, and they have been, in the early days. The blade speed is lower than can be reached using titanium or steel, so more stages are required.
