Huricane Mk I 100 Octane perormance tests 1.07.18301

[Crumpp]

When was that admitted that the Merlin delivered 12lb boost in 1940 ?

When was it approved for sustained climbs?????

[5./JG27.Farber]

Please explain the chart building and how to do this. I would not mind doing this for the 109, cheers.

Farber, there is an explanation in the .doc file in the zip file in my OP. Its basically chart building from the output data using Excel or OpenOffice. Let me know if there's anything that isn't clear or needs expanding.

EDIT: I just updated my OP as I saw I had not attached the zip file and then I replaced it with a few corrections to the instructions.

I would also like to see ME-109 climb and performance tests. I bet it's borked too

It was approved for 5mins at 12lb boost/3000rpm in 1940, and it was up to the pilots on how and when to use the power; including sustained climbs:

But Seadog, Crumpp says the Pilot's handbook says nothing about 12lb boost.

Thanks for posting Klem

Just did a quick comparison of Hurricane Mk I 87 Octane vs 100 octane at 1000, 5000 and 10000 feet.

Seems the old 87 octane is faster than the 100 octane

Would appreciate it if anyone else would like to check that.

Your figures are without boost. The difference was AIUI (which may or may not be correct ) that 100 octane allowed more boost at low level. So figures without boost shouldn't show a difference, and with boost only up to FTH.
