One of you said you had a translated flight manual for the Ki-84.
According to the theater interrogation reports all they were able to find on the Ki-84 was the prototype flight manual which was issued to the training unit.

Quite possibly that is what you had.
Do you have any more info?

Hi Michael,

It's been a long time since I've read it so my memory is vague on it.  I don't recall it anything about it being based on a prototype, but that doesn't mean that it wasn't.  

I received a bunch of data about 5 years ago when we first started and I thought that was in there, but I'm no longer certain as I can't seem to find it.  It's possible that that was something I had when I worked on a previous game and no longer possess it.  I believe it came from the Wright Patterson archives, but I'm not sure of that either.  I still have some boxes I need to search through and hopefully it will turn up.

TY ,Michael Johnson , for taking the time to expound hear for us I find this all very interesting.

Oh, and i agree that the Ki-84 was an excellent plane in most ways better than the P51 or P47 (yikes! that is heresy! burn him!)
but the reason you might fly something else is because the Ki-84 was a dog over 23,000ft.

In historic events played in the game, this is always a problem for the Japanese.  The blue planes and USAAF planes dominate them at high alt.

But most of Aces High is played in a mixed-plane environment that often becomes a low-alt gladiator pit, and in those situations most of us expect the Frank to dominate.

I have to have something to show for all of my time at NARA!

I've been told that NARA should have more than one report on  Wright field tests  on Ki-84 but no one seems to be able to find them.

PRO has a short report on Seafire vs Ki-84 tested in Clark field and there is also a short technical report  on various Japanese planes.

Useless against B29's. Or their escort fighters at high altitudes.

Much of the saved weight was because of the lack of a real supercharger.
In fact the supercharged version, which never went into production, was a slower aircraft.

Michael, you ever get to the Zoo often ?     A bunch of us a couple years ago met up down there for a little tour of the facilities.

[Michael Johnson]

Of course! I live 2 miles away!

lots of fun.
My sister & brother-in-law both were air force officers in Dayton so i made it down to Wright-Patterson all of the time when i was a kid.

[WHATTHEHELL]

Aye, I am about 40 minutes from there and will be making a trip down to the Zoo next weekend.

A few years ago, I sent off to the Smithsoian Institution inquiring about:

 Captured German & Japanese Air Technical Documents.

 The Smithsoian has a ton of this material, and it can be obtained, by filling out a request for that you can get from them @:


 Archives Division, Room 3100
 National Air and Space Museum
 Smithsonian Institution
 Washington DC 20560-0322

 
 Initialy I requested a listing of files they had on various Japanese planes, and I receaved several pages listing referance material for all kinds of Japanese aircraft.
  I can not recall specififcaly if I requested data on the Frank, though their are some files they list as having for it:

Real 3744 Frame 134

Title: New Japanese army aircraft Frank 1 and Peggy 1 and miscellaneous developments.

Abstract: Technical descriptions and discussion of the designe characteristiscs of the Army Fighter Frank 1,.....

 I did get a ton of referances for the P1Y1, Ki-102, and N1K2, amongst other types.

 This packet I sent to Pyro (I photocoppyed the one I received), some years ago, the donw side to this wealth of infermation is that it takes some time to get it, once you fill out the forms it takes 8 weeks to get the material.

 The documents in general come from:

" In the finial days of ww2 the advancing allies captured a number of German and Japanese documents on various technical subjects. The United states Army Air Force (later the USAF)  had a number of these documents microfilemed by the Air Documents Divishion. Technical Infermation Section (T-2), Air Material Comand, at Wright Field, Ohio (now Wright-Patterson AFB). This microfilm serries containes documents pertaining to aircraft and aeronotical subjects, including aircraft manuales, flight test reports, and engenering studies of aircraft. The Material does not Include compleat sets of drawings for aircraft. Most of the documents are in the original language, while most indexing and tittle pages are in english.*"

 * Although in the lists I have prety much all the material seams to be fully translated.

One page of referances for materials that can be obtained show as an example:

NASM microfilms appear to contain wide variety of documents, not only captured german and japanese documents but stuff like RAE reports and intelligence material like that TAIC report mentioned above. Normally only descriptions of the documents are written in english but there seems to be some translated documents among (like japanese translation of the german wind tunnel test on the P-51 wing).

Quality of the microfilms tend to vary a lot; I ordered some microfilms on Bf 109G some time ago and some of the frames are totally unreadable while some are very clear. The good news is that the documents were not destroyded after filming and  USAF gave large part of them back to Germany and Japan in the sixties or seventies. I don't know what happened to the Japanese documents but german stuff was scattered to various archives in Germany (at least Bundes Archive and Deutches Museum).

Documents were microfilmed purely in random order and AFAIK they have not moved file cards to computer database yet, so looking for something specific will be quite time consuming project despite you have copies of the file cards. In my case I co-operated with some other people which helped a lot and reduced costs (one microfilm costs IIRC $25).

First off, sorry for posting similar questions in two different threads, just stumbled across this one.

To Pyro: I hope you found that manual!

To brady: What do your documents say about the performance of the Ki-84?

To butch2k: What's the difference between the 2nd and 3rd columns?

I could be wrong but the engines seem to be almost the same while the difference in performance is fairly drastic (presuming that 6&9 is a typo for 679 km/h and S.L. (Sea Level?) 584 km/h)

Time to altitude also seems markedly improved if I'm reading it correctly.

[brady]

I dont have the actual documents just he referance cards showing the info neaded to order them, howeaver On another thread regarding this topic I posted a Link provided by Wotan refering to the question at hand that provides a lot of evadance suporting the 420mph spead.

[RTSigma]

Ya know, you make this a limited plane, AKA, limited to the CT in certain scenarios....I'm sure you'll draw A LOT of people there.....

[Booky]

Hmm, Cannons and 420mph I think this will have to unperk my hog
