As far as I know liquid propellant rocket engines are notoriously complex, and operate under even more extreme conditions than modern airplane engines

  Don't underestimate how complicated modern high bypass turbofan jet engines are. Way more R&D money had gone into the latest designs than went into e.g. the Raptor engine. A crazy random fact is that there are entire turbine parts that are a single molecule, yet are bigger around than you are tall.

    Single molecule thin? Or is it something polymer like? That's intriguing.
    • CydeWeys 7y ago
      No, the entire thing is a single large molecule, despite however many kilograms it weighs.

        Intrigued! (I thought some plastics, polyethylene for instance was always single molecule, but it's seems I'm mistaken.)
