Intersesting reading.

At least I found here again what I hve read for years in UK/US books and not such upside down history account. I guess I am not the only one here with such a feeling.

Regarding the merlin power, may I suggest we give enough details giving perf to determine if the it was a static test run or an in flight measure (typically corrected to 10kft with RAE formula).

Engine data in RAF at the time depict performances WITHOUT Supercharger or being corrected with pre-war formula (hence the the extra 15/30% power) - RR heritage trust / The perf of aero eng / pg 5.


This illustrate why with all the raw data that are now available on the web (but with sometime questionable sources) giving any interpretations or deductions without taking into account years of research from historians is somewhat hazardous.

Usually it ends up like this : all before me was wrong listen what I have to say... Man shld be cautious when entering such a buffer zone

I have in mind that latter analysis in war corrected the early data with the new state of the Art resulting in the normal linear improvement curves we have all in mind of teh Marlin during WWII.

Interestingly I found the related article in Wiki really good. Have a look !
