    "The Performance of a Supercharged Aero Engine" - Discrepancy b/n Fig 32 & Table III.

    There are multiple inaccuracies (simplifications, wrong assumptions, mistakes) in that booklet. However it still provides a very good guide of how the many variables impact the supercharger and engine performance. It can be used to estimate the impact of a change in a variable, but do not...

    A new book in my library.

    That's a lot of Bf 109 books. I'll add a recent 109 purchase of mine: 'Das Jagdflugzeug Messerschmitt Bf 109 - Technik, Eigenschaften, Leistung, Stückzahlen, Bewährung' by Michael Baumgartl.

    Bf-109 books

    I don't think the books that you mention are very technical. You mention Prein, but I suspect you mean Jochen Prien & Peter Rodeicke, however even that book I would not really call technical either. What exactly do you mean by "technical" and what exactly are you looking for? Really technical...

    Why was the BF109 so slow compared with the P51?

    The maximum manifold pressure (boost) that an engine is able to operate on is definitely a function of compression ratio of the piston engine. The higher the compression ratio of the piston engine, the lower the manifold pressure (boost) that can be used. Greg does not seem to understand that in...

    100-octane fuel in the RAF in 1940

    I don't have that book, but judging from its TOC it might be less interesting than the title implies: Taken from: 100-octane (ebook), Peter Varey | 9780953844043 | Boeken | bol.com

    F-82F/G/H exhaust stubs?

    It seems to me that the exhausts are split in 2, not 3, but maybe you have better photos.

    F-82F/G/H exhaust stubs?

    My impression is that the flame dampeners on the F-82F/G/H merely diverted the exhaust sideways and somewhat downwards, instead of backwards:

    Wing Loading & Stall Speed Question

    "Note that the inlet alone provides 70% of the thrust, the spike is 14%, and the ejector pushes with 27% to make up the total thrust for the aircraft." That is not quite right. The spike does not provide 14 % of the thrust, but provides a drag equal to 14 % of the thrust. The inlet 0-2...
