Oh geeez, and people wonder why Oleg stopped posting ROFL. So you picked one document that is pretty funny if you read it carefully.
First of all they announce no problems but immidiately in the first paragraph they mention spark fouling so OK not a big problem they say and then the document continues with a brief summary:
SpitIX/Merlin 66 - backfires!!! if that is not a problem then what is, Osama flying airshow program over BigBen? Ok so they believe this can be solved by retarding the ignition, believing in something will work and it actually workings is a bit different I would say...
If things were so great why reverting back immidiately after V1 threat stopped?
SpitXIV - no failures that could be associated by use of higher grade fuel hmm interesting, again: If things were so great why reverting back immidiately after V1 threat stopped? Just for reminders +21lbs never saw combat in the war(which ended about a year after that), while +25lbs never showed up. Why?
MustangIII - just read, even during the operations they had to lower the boost.
Tempest/SabreIIa - allegedly no problems, not what I've heard but OK even like this, why reverting back to 9lbs immidiately after V1 threat stopped? Also since I generally want to talk about 13lbs for which I claim was a rarity no lesser than TA-152C oe 109K4C3 this is what R. Dennis said about it:
"All our machines were fitted with Rotol airscrews when the maximum rpm were increased to 3,850 from 3,700 and boost to +13 from +11, as the DeHaviland airscrew could not absorb the added power and more than once shed a blade, with somewhat detrimental effects on the engine!"
Wow sounds really reliable, squadron service imminent - in Japan as Kamikaze lol
Also one note from most favourite site for certain types of people:
"The writers have not yet found any flight trials with engine limitations set at +13 lbs./sq.in. & 3,850rpm. We would be grateful if anyone having such material could contact us."
Yeah I really wonder why there is no such stuff lol
