The helpful hint for the Germans would be not to use steel for turbines as it melts. But they didn't have access to other metals to use as high-temp alloys, so there was no way around the problem. However is the average life of an Me 262 less than the 10hours before the engine conks out?
The 004 is bulky, very heavy, has awful fuel consumption and is generally inefficient. The RR Welland had half the weight, much better fuel consumption, but most importantly was reliable.
The HeS 011 axial+centrifugal flow,which was to power most of Luft 46, never got beyond the "pile of junk" stage. It produced nowhere near its design power, still had awful fuel consumption (but better than 004) and wasn't reliable when used by the USAF postwar. This compares to the Nene running at 5000lbf reliably in 1944.
