Hey!
I am trying to find some figures on the environmental conditions a turbine blade in a Jet Engine would have to withstand, and the materials that are necessary to prevent the blade from failing.
I have taken the example of the 'Trent Engine' or so I think it is called. I have read that temperatures in the combustion chamber can reach temperatures of up to 2000 degrees. Would this be the temperature that the blades are exposed to, or would there be a large variance in temperature. I say this because you would need an accurate measurement of the temperature, from which you would decide on which materials to use. I would have thought that the temperature would have been relatively similar to that as the blades aren't made of a single metal, but of ceramics or alloys. I'm sure you can see this isn't really a field that I know a lot about but what other environmental factors would this material have to cope with? I can think of changes in pressure and the huge speeds the blades would move at as other problems.
Regarding the properties the material would have to possesses I have considered Stiffness (Young's Modulus), Yield Stress, Plasticity (or the lack of it), elastic strain and the breaking stress of the material. I think Once I have a few material to work with I can research them.
I have google searched around but have found it difficult to actually find a site that answers my question directly while also allowing me to do a bit of reading around it. If anyone could provide me with a link or two I would be most grateful.
