alt Hacker NewsThe basics are pretty distributed, further work involved increasing lifespan at high temperatures, but also some work towards switching at least some turbine stages from separated blades into "blisks" - entire turbine stage is one crystal, including the hub.
I've heard it said that growing crystals in gravity is tricky... If we could do this in space, gravity free, we could get better crystals.
Is that correct? Pardon for asking a bit of a question to your comment. I don't know too much about growing crystals for things like jet engine blades.
