ISTR that when the Meteor entered service - Time Between Overhaul for the RR Welland was already 180 hours compared to the absolute life of 10 - 25 hrs for the Jumo jet engine - the German engines were simply not production standard - I know much has been made about lack of certain materials in germany but in my view they tried to run before they could walk with jet technology and would still have struggled with blade technology and engine control problems for a few more years yet even if there was not a shortage of certain materials for alloys etc.
Compare the design philosophy of both engines - The chunky RR Welland looks like it had a chance of running for quite a few hours safely but The Jumo looks fragile (especially the turbine LOL) and I honestly do not think it was a good design !
