109 e3b against spitfire II

[TomcatViP]

At first I wld like to say that I'm sry to all reader for this dual exchange.

Secondly I did not quote you to shorten those otherwise long answers that tend to be felt as walls in a forum pulling away the reader interested by the title of this topic

Let's go :

Adiabatic = when E is exchanged without loss of Calorific energy

Simply said the s/c depend of it's operating inside Temp that drive the efficiency of the compression

There is no adiabatic transformation. Isentropic is also an approximation to figure out the inside Temp that RR could not measure in 1940. But yes that what you plot. But who cares ?

Better fuel : higher piston head temp -> eng wearing. This is well known from car's tuner. You'd see a lot of interesting threads on that subject without over complicated words.

By the way the DB605 is no more than a revamped DB601 but with the same minor details that change and took so little time to arrange before being sent in full production

Wasn't WOT 5000 ft ? -> it's far from any rated alt - look like more for a naturally aspirated eng. I guess that the redesign of the intake was the partition they played here

Yes yes you 'r right impeller are quite easy technology once you 've got the backup of strong industry supplying nice raw materials proof of any small glitch. Oh yes you'r right ... Of course the Russians, The Italians and the Japanese just might hve miss read the same early studies.

Si vis pacem para bellum : UK proved here her superior "governing awareness" (despite the Munich debacle)

RAF not NHRA

Using copy/Paste as well :

Merlin XX !!

ALT(ft) SHP BHP (diff correspond to the power used to drive the supercharger)
15K 1267 1048
20K 1298 1073
20K+ 1362 1126
25K 1162 960
30K 945 778
35K 700 568

At 20K the eng is fed with sufficient amount of air to regain is low alt power. But it still hve to drive the s/c. This everything abt turbo-charging an eng.

FM : 1c far superior to any Modder (I am sry to hve to write that)

Patents ? I never doubt you was a talented individual. Well let's pat our back and share our patents together one day
