> What do you mean by "metals don't actually withstand temperature"? As in the raw metal would melt were it not for the cooling vanes? A small addition to the sibling comments: Combustion temperatures in modern turbines are around 1400C, if I recall correctly, but the best nickel superalloys go up to 1050C or thereabouts (for long-term operation). To close this gap, the use of high-temperature alloys is supplemented with active cooling and ceramic coatings, as stated by GP. |
