In the mid 1940's The Americans were so far behind in jet engine production the English had to ship one of their jet engines over to the USA to examine. I was an aircraft jet engine mechanic in the 1960's and in Tech school we had several axial flow engines to show their working internal parts. These axial flow engines were so different from the J-79 made them look like a cookoo clock costruction. But the axial flow engines got the job done even though they had to be overhauled after 25 hours of operation. The types of metal available were the problem with keeping the axial flow engines from throwing turbine blades. Until a suitable method of keeping the blades attached to the hub for longer periods was discovered the axial flow engines were doomed.
