No, it does not. See page 56, column 2, near the bottom of the page.( Spitfire, the history!)ok lets read page 56 column 2, firstly this chapter is MKIs (Type 300) We can ignore the underside view as a diagram is hardly evidence of rate of rollso we have the text, which beginsOctane fuel put the British fighters on par with Luftwaffe and continues talking about Fuel and Propellers
But what you leave out is that it also talks about engine longevity as it relates to power usage! for a Merlin II special! in 1938, an engine rated to 2800rpm but tested at 3000rpm in over boost conditions (hence 100hrs life span)
100 hours on 87 octane at 6-1/2 pounds boost, to 10 hours on 100 octane at 12 pounds boost, to 2-1/2 hours on 110 octane at 18-1/2 pounds of boost, to 15 minutes total at 25 pounds of boost on SR24 Zip fuel!as pointed out that this was over boost or emergency power settings not cruise setting as you imply
I used this part to show the futility of using such large throttle openings willy-nilly as the original poster wanted.
rubbish you thought I wouldn't check and now change the subject to another, one I might add is irrelevant as the data only applies to the merlin II which had been relegated to training squadrons by the BoB and completely obsolete by the period we were discussing (the MKV ) by whole generation (the MKII) so has as about as much relevance as the inside leg measurement of Douglas Bader
I should have been more careful how I worded my reply, but it was late at night here when I did it. In both cases, the early Spitfires were rated at 27 degrees per second rate of roll,The only reference to this I can find is your claim to have read it somewhere (conveniently you cannot remember where) 27/sec would equate to a 360 roll in 13 seconds are you seriously expecting anyone to believe that rubbish?
as posted her in other threads. As far as I can see, the Spitfire book is completely devoid of any figures relating to the rate of roll of early spitfires and more importantly how rate of roll changes with increasing speed.
Watch this film and count the seconds as the various Spits roll 90 degrees!
how does the rate of roll in an air display relate to its actual performance? for any plane? they are always well within its limits its a display NOT a race
also another point you keep raising, the aileron reversal on the Spit, this was proved to occur at 480mph on the MKI rising to 780mph on the MKXIV, so whilst you could hit it in a high speed dive in a MkI are you seriously claiming that a MKXIV was capable of 780mph? the speed needed to encounter aileron reversal?
