Thanks Tomo! Google tells me that Start Und Notsleigstung means "Start and Emergency Service." Since it has a three minute limit I guess that's more or less equivalent to War Emergency Power? On the DB 601 and 605 engines the highest ratings are generally listed as Höchtsleistung (High...

Who here has a high degree of familiarity with German engine ratings? I'm trying to calculate the power loading of various aircraft as part of an effort to come up with a workable formula for translating aircraft characteristics into an in game agility stat. But for a lot of German engines I...

So much for the claims about being able to throw the A-20 around "like a fighter"! I haven't read the manual, but I did find a (somewhat cheesy) old War Department training film that emphasized that the A-20 was not an acrobatic aircraft or a dive bomber and advised pilots to limit bank angles...

I have actually been crunching a lot of numbers for wing and power loadings lately. It's what prompted me to make this thread. There are a couple cases of bombers with similar engine fits and weights where one had 50%+ more wing area. The aforementioned He-111 and Ju-88 (I was thinking of the...

Can anyone verify that the 427mph figure for the Ki-84 was actually achieved in testing rather then being an estimate? The Interim Report No 3 that @MiTasol posted includes speed and climb figures on the "Factual Data" page, but section 3. d. Climbs says that "It is apparent that the rate of...

Agility is not a term generally associated with large WWII bombers. Its one I tend to associate more with fast small to mid size bombers like the Douglas A-20. But it's my understanding that low wing loading is a reasonably good indicator of maneuverability, and some bombers like the He-111...

One opinion I saw expressed was that pilots operating close to home would likely use WEP or equivalent capabilities more readily then those operating far from base. Anyway it looks like I had a poor understanding of what the military throttle setting was. The explanation of power settings in...

I have been collecting data on the maximum outputs of various WWII aircraft engines, but reading discussions on this forum have made me question my approach. If use of War Emergency Power was largely avoided even in combat, then it seems like the military power rating (and its equivalents in...

Belated thanks, @Snowygrouch. Has anyone here actually read the oft mentioned USN evaluation that rated 20mm three time as effective as .50? I'm kind of curious about it since it appears to evaluate the 20mm's advantage as much more significant then the RAF Operational Research Greyman...

Hope you don't mind me reaching this far back, but I'm kind of curious what the scale at the bottom of the second image refers to. Weight of metal? The results of some sort of special formula cooking up for measuring destructive power?

Interesting! I find the bit about adapting the G.55 to carry torpedoes particularly interesting. As mentioned previously I've been suspicious of claims that the carrier based Re.2001s would have had torpedo capability as there was only a single land based Re.2001 torpedo fighter, but if the...

I've read that some of the later Japanese and American aerial torpedoes were good for drop speeds up to ~400 knots/740km/h though I think they included drag producing features to slow them down after release (that and I'm once again wondering what torpedo carrying aircraft were actually capable...

Thank you for your replies. I should probably have posted this earlier, but here's the scan of the page/document I mentioned in my original post that claims a 2800 meter range. Unfortunately I do not know the original source of this page/document as the source was not provided on any of the...

Does anyone have access to relatively reliable sources on the BT series Bomben Torpedos Germany developed/was developing near the end of the war? I know they've been mentioned a few times in various threads on this forum but the focus has generally been on the aircraft that could carry the...

I've often seen the B-25J quoted as having a maximum speed of ~275mph (440km/h). However, wwiiaircraftperformance.org has a scan of a 1950 dated document that lists a considerably higher maximum speed of 255 knots (295mph/472km/h) at 15,000 feet for the J model -and that's at Normal Power, not...
