British v. German jet engines (Pete Stickeny)
Pete Stickney wrote in another thread: (The Aliies, after all, succeeded in 1943 in producing what the Germans could not - practical, reliable jet engines that could be flown for more than a day before needing to be overhauled, and which could be worked on by typical mechanics. Before the Me 262 appeared in 1944, both the Americans and the British were running engines with more than twice the thrust, and 10 times the life of the best realized German efforts.) Pete, the rough figures I carry in my mind is 10 hours TBO for the Jumo engine in the Me 262 and 25 hours for the GE? engine in the P-80. I have also seen 50 hours mentioned in a 1945 briefing about the P-80. I'd be grateful if you could flesh out the parenthesis. The only engine I know anything about is the Whittle turbojet as modified by GE for the Bell YP-59A. I never followed up on what changed before the P-80 got running. And what about that P-80? It seems to have had an unwonted number of crashes for an airplane that turned into the longest-serving jet ever built (still in service, as I understand, as the T-33 in recce and light-attack roles for various air forces). Thanks! all the best -- Dan Ford email: (put Cubdriver in subject line) The Warbird's Forum www.warbirdforum.com Expedition sailboat charters www.expeditionsail.com |

Dont know about the GE engines but the Wellands used by the Meteor in 1944 were rather conservatively rated at 180 hours http://www.enginehistory.org/r-r_w2b.htm IRC the first production Welland ran for around 2000 hours on the test bed.
