S!
That conversion to new plane is nothing new. Same happened here to our pilots being transferred from older types like Brewster, Curtiss Hawk etc. to the Bf109G..most only got instructions on what whas what and what to check and note and off you go :) |

Just found this. From the list of mkI serial numbers in M&S... All spitfires built after the 1/6/1939 were Merlin III. Only 74 were Merlin II On the 22nd March 1940 a letter from MAC ordered the change of production and specified that all MKI's were to have the Merlin X installed, starting from Serial Number R7023. This was to bring them upto MkIII standard. events overtook this instruction and from R7258 Merlin 45's were fitted, thus bringing the Mk I upto MkV spec. Why would they do this in march R7023 was built on 28/1/1941 R7258 was completed on 5/4/1941 Every single spitfire produced after that date was a Merlin 45. Simple fact is there were no operational mkI's around in 1942. Any that had survived that long were in OTU's all the others were converted to MkV's or PR's or whatever.. |

http://img267.imageshack.us/img267/6...ngregiment.jpg One thing you will not see in this process is the what is termed the "phase III" testing. That is not done by the service and is the responsibility of the contractor, in this case, Rolls Royce. Phase I is concept development and is also performed by the contractor. In 1939 we see the Phase II testing which is a proof of concept type testing and is performed by the service. We don't see the Phase I or Phase III testing as they are not done by the RAF. Any documentation is the sole property of Rolls Royce. After Phase III testing, the concept will then come back to the service for Phase IV testing. Quote:

Outliers are not examples of a mean. |
I work with Rolls-Royce and I'm pretty sure they don't use protocol from the 1981 flight testing conference in Las Vegas, let alone had the forsight to use it 42 years before the conference.
One of our lads operates CNC's for RR too, making compressor blades for jet engines. I'll ask him if your stuff has any relevance whatsoever, although I think I know the answer already...... |

This is another example of you thinking that because you have expertise in engineering and warbirds restoration that whatever you say is right. Well, I'm an expert on the Battle of Britain. I simply wouldn't even entertain the idea of arguing with you about piloting, restoration or engineering because I don't doubt your credentials. Yet in the face of overwhelming evidence both hard and circumstantial you're still arguing. Why? Is it to save face. Please sum up for me your argument in a concise way, as to why you say that fighter command hadn't completed the changeover in it's frontline Spitfires to 100 octane fuel by the beginning of summer 1940. Because that's what this is about. You've tried all sorts of different arguments and seem to move stealthily around the subject, but come come, let's cut the crap and cut to the chase. What have you got to lose? Edit : changed frontline fighters to frontline spitfires. |

Second, the AIAA 81-2375 is the history of flight test development!! If you could access the AIAA library, you could get your own copy. Maybe on some standard day they might let you in!! Ha ha ha ;) You have to graduate from an accredited Aeronautical Sciences curriculum for membership. https://www.aiaa.org/ |
