ADI tank on F-51H is located behind firewall, underneath cockpit floor. I remember this was shown on the later SAC from July, 1950.

Apparently there were several post-war flight trials by the British between Fw 190 D-13 and Tempest V. On June 25, 1945, German pilots Major Heinz Lange and First Lieutenant Günter Josten had opportunity to fly the D-13 (unknown if MW 50 was used).

Great! Is it possible to show "plate 2, 3 and 6" as .jpeg or .png files? (better for me) :notworthy:

Hmm, what did you mix? The upper parts in your scans are the 70-inch full throttle dynometer runs. Below looks like other charts from another run... Would be nice to see full AEL report 😁

Please, mate, need little bit more explanation :hello2: On these two graphs I only see: - zero RAM: two runs (different engines), with 70 and 70.5 inch (high gear: 2300 HP at critical altitude 6000 ft) - so-called "420 mph" RAM runs: with 70.1 and 70.3 inch (high gear: 2350 HP at - thanks to...

You're right, I remember another report of R-2800-32W, they only did „dry" power runs. As commonly known, if you equip a supercharged engine with water injection, you can generate higher boost pressure = more power. Water usually is injected in the eye of impeller, respectively before...

Sorry for maybe OT, but I'm a little bit confused about mentioned BHP figures of R-2800 C- and E-series. According to the above file a postwar CB 16 needs obviously only 59,5 inch (wet) for 2400 BHP - I think this is without RAM. This document of a (wartime!) E-series 34W shows motor needs...

Is it known why Jumo engineers doesn't changed much earlier to 4-valve-heads, as example with the precedessor models 210 or 211? :scratch:

Thank you for detailed explanation, great! :thumbright:

Thanks for the link, big datas... :thumbup: From what I understand special dynamometer runs are usually manufacturers job, not up the military flight reports. Is it known why Calibration Reports don't include water injection test? "Operating Limit Charts" in many flight manuals only show...

Hi Tomo, thanks for posting, that's a very useful overview! A note: on a German forum I've read, this - obviously post-war compiled - documents have a bug. When it comes to "Verdichtungsgrad: Zylinderreihen links/rechts" they swapped the correct CRs. Left bank (view from cockpit to prop)...

Hi @all, I don't know if this maybe has been topic before - but found this very interesting file (caution, 77 MB !): https://apps.dtic.mil/sti/citations/ADA800142 The R-2800-32W is also known to have water injection, but from what I understand it's strangely not mentioned anywhere in the...
