Somewhat. From Dr. Price:
"The Me 262 was suffering severe problems with its engines however. the Jumo 004 was the key to the new fighter's sparkling performance, but it was also the first turbojet engine in the world to enter large-scale production. It ran at much higher temperatures and greater rotational speeds than any previous aircraft engine, and a host of fundemental problems had to be solved during its design. Moreover, the usual ingredients of high-temperature-resistant alloys, nickel and chromium were in critically short supply in Germany and could not be used. Variuos substitutes were employed. The engine's combustion chambers, for exmple, were manufactured from ordinary steel with a spray coating of aluminum baked on in an oven to increase their ability to withstand high temperatures. Such palliatives, though in many cases clever, were only partially successful and the average running life of early production engines was little more than about 10 hours...."
Unchartered waters they were in for sure. Hitler had his hand in fouling it up but it wasn't all his fault.
