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. $\endgroup$

  • $\begingroup$ You should be more specific. Which gas turbine? $\endgroup$

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.
