alt Hacker NewsHm I just read an article here recently that was saying that Americans had an edge in jet turbine blades production over china because Americans figured out how to make single crystal jet turbines using this same method. I wonder what the difference is.

An edge that dates back to the late 60's/early 70's? How soft is that edge by now?

So far as I know you could say Americans, but it is specifically Canada that most of the best engines are coming out of. Maybe Pratt and Whitney are using blades from USA, IDK, but anyone in jet aviation will be able to tell you the world would be fucked without Pratt.
The Veritasium video on how jet engine turbine blades are "grown" in an aligned crystalline structure for enhanced material properties (e.g. thermal performance) is absolutely fascinating & well worth a watch:
