Did anybody or could anybody give any info if War Emergency Power on P-47M/Ns reduced power above about 32,000ft so that at a higher altitude military power rating was actually more efficient? This is a long and interesting thread that may have a Engine Power vs Altitude chart for the...

Just looking at some soviet aircraft of wwii the most distinctive feature is the diamond wings, which basically all of their fighters seemed to feature. Any idea why the soviets were so obsessed with this tapered design? and any idea what the big benefits and disadvantages of it were? I...

Well besides real life evidence it works in every single air-combat game that has ever been, even the goofy ones like the "Battlefield" series :p its simple geometry and "energy" states, so long as its performed correctly it works

Yeah that was the He 112 V10 with DB 601Aa (also V11 with DB 601A) Very VERY little data about it but "German Aircraft of the Second World War" makes a mention of it https://books.google.com/books?id=AvTgjHwl1sMC&printsec=frontcover#v=onepage&q&f=false (page 138 and 139) It says that it was...

Nothing much to add, especially as i don't directly have a link to the discussion, but a buddy of mine who used to frequent J-Aircraft and normally is a great knowledge base on Japanese aircraft once mentioned that they had a large discussion about the Ki-83s top speed and to the best of their...

This is the best place i can think of to ask, so hopefully you guys can help me out. Recently i have been trying to get a better understanding of how well .50 caliber ammunition worked in combat. I've looked into threads/posts but there isn't really any exact or technical conclusive there and...

Newbie here who is just wanting to learn, share the little i know, and whatnot I am genuinely interested in the story of how and why Rare Bear used to make so much power but isn't anymore, what is the reason for this?

Happy you enjoyed it, another comment or subject about zoom climbing real quick. Maybe I'm barking up a tree that has already read these documents, but i always found the F4U vs FW 190 A4 documentation interesting, http://www.wwiiaircraftperformance.org/fw190/ptr-1107.pdf Specifically the...

Don't get me wrong, i think the He 162 was a great design and if it would of came from a environment which had skilled labor and the materials to build it properly, and was designed specifically as a fighter with the Me 262 being more of a bomber interceptor then atleast on paper or in a...

There is a HUGE distinction between how lightweight and high power planes like say Spitfires, mid to latewar Yaks Lavochkins, BF 109s, or even A6Ms can utilize zoom climbs and how heavyweight, high speed, but lower power to weight planes like a P-47, Tempest, or FW 190 can utilize a zoom climb...

Even if you are aware that Japanese aircraft were only tested at Military power rather then WEP by Japan, and that the true top speed of the Ki-100 is probably greater then 360mph, i think its obvious that the Ki-84 which could do about 430mph (utilizing War Emergency Power) and the J2M5 which i...

Something i have been wondering is how does one gauge a planes full potential performance if it was only ever tested at say "Military" power, but had access, say 5 minutes, to increased boost. In the case of the Spitfire MKii there is lots of good data for 9lbs boost, but the aircraft was...

My point was only that all 3 of those aircraft basically, atleast so far as i can tell, were turned down largely in part because of Willie Messerschmitt fiddling. Although again if i am wrong and it was more complicated then that i'd love to learn, working on fairly limited info.

I like BF 109s quite a bit, but if canceling them, or atleast reducing Willie Messerchmitts weight with RLM would of let the FW 190C, Fiat G.56, and He 100 develop into actual fighter aircraft i would of happily have seen some of Messerscmitts projects cancelled and or backing reduced if we are...

Just wondering if anybody knows climbrate, either chart or in text, or a Spitfire Mkii with a Merlin XII engine. I'd be happy with climb and speed charts but if all someone has is climb that is OK by me, so long as its relatively specific for altitudes up to atleast 6km ideally higher
