The metallurgy of the fan blades has also vastly improved.
Monocrystaline fan blades have very different material properties from the polycrystaline blades that (I am guessing) were used on Concorde.

- solardev 4y agoThanks for sharing that link! It's amazing what people were able to come up with in the 60s, before computers and Wikipedia and 3D modeling... wow. One of the patents mentioned is how VerSnyder was able to grow a turbine blade in a monodirectional crystalline structure: https://patents.google.com/patent/US3260505?oq=versnyder+1966 https://patents.google.com/patent/US3260505?oq=versnyder+196... just using a special mold and a specific alloy. That would later form the turbine blades of the SR-71 Blackbird.
- chasil 4y agoI just reread it. All of it was familiar, but I had forgotten a few of the details. The first monodirectional blades were introduced to commercial jet engines in 1974, so Concorde definitely did not have this technology with the original engines.
