Ceramic Turbines
About 5 years ago more than 1 person told me that research was under way into ceramic turbine blades that could withstand much hotter temperatures, the idea being that an overtemp on start would not be such a big deal as it is now and also that the engine would be able to run hotter generally allowing it to produce more power assuming within N1/Ng and torque limits.
but I havent heard anything since !
did I dream this? any progress? any working examples? when are we likely to get this in production? or is it all just nonsense?
