Indeed. The US initially appeared to have followed the lead of the British
in that regard. There was a lot to be learned about axial compressors at the
time. Centrifugal compressors were easier to design and build. Even at that,
comprises were made in building them due to production machine limitations
of the day. Take the successful Rolls Royce Dart engine for example. The
forward curved leading edges of the compressor blades we made from a
separate disk then stacked on the base section. By the late 50s, parts like
that were made in one piece. Pattern making and tracing using hydraulically
controlled machines were general practice in the day. A lot of very skilled
tradesmen doing incredible things with what they had.

Axial compressors and variable stator compressor geometries were the
big contributors to the pressure ratio and efficiency increase.
