Ki-84 performance data
« on: April 23, 2002, 10:35:22 AM »
Ok, I've got some performance data for the Ki-84.  One is all in Japanese, but it does have performance curves for climb, speed, and something else that I'm can't remember off hand.  

The other document is from TAIC manual, Planes of Fame pub. ISBN 0-915-464-03-2.

Here they are for your viewing pleasure.  If you want these you had better take them down, as the forum that they're posted on will probably remove them pretty quick.

Nice post, I wonder if that is 150  and 350 rounds per gun for the 20mm and 12.7 mm ????

     Does anyone have a figure for the ammo loadout on the Frank and did it vary from model to model?

Mitsu,

On the Japanese chart what is the graph in the upper left corner of the four graphs shown?  It has m.p.h. on the X axis, but what is on the Y axis?

Thanks,
Spritle

By the way someone better save these quick as they will probably be gone soon.

a Y axis in the upper left graph shows "Range (miles)".
Its graph is "Range vs. Speed".

Sorry to burst your bubble's guys, but alot of the data from the TAIC book are "estimates",  based upon past performance of other aircraft or interpolations & calculations based upon recovered enemy wrecks. (FYI I have the same book and I've discussed the performance data in it with Pyro before)

Very few of them are actual flight test data.

I have no idea on the Japanese data though.

Vermillion,

I don't have the TAIC book so I don't know anything about it.  What is the history of the book itself?  When was it first published?  Is it possible that the performance data is from one of the 2 or 3 captured flyable aircraft that were tested at Wright Paterson after the war?  

The Japanese page is from Famous Aircraft of the World on the Ki-84.  I have this book.

I own the Plane of Fame TAIC manual version Verm referred to and AFAIK the data is just estimate for most aircraft. I also own the original June 1945 revision of the TAIC manual 1 and the October 1944 revision of the ATAD T1 book, both dealing with the Japanese aircraft.
From the ATAD manual :
"Except where otherwise noted, performance figures represent the best estimates of the engineering Division of BuAer and have been calculated after a careful analysis of information derived from intelligence, captured equipment, drawings, and photographs."

The curves published in FAOW come from those books not from manufacturer data.

Some real test data is available through the NASM, but do not expect too much.

The Ki-84 was really test flown by TAIU-SWPA at Clark field. They also test flew several other Japanese planes there .

God I would love to see this plane.  NO it won't be perked but it would replace the la7 and Spit I am thinking.  Such a sweet ride.  Would love to see other JP rides as well to compliment the Axis rides even though I love my FW's.

excuse me.

Do you know?
Ki84 is Max speed in Japan is 624km/h.
But, It's increase rototype value.
Its engine is not Ha45-21(2000hp), Ha45-11(1800hp) is.
but, Ha45-21 have limitter(1800hp) on front.
This limitter was not removed at war finish.
But,I heard a few N1K2-J and Ki-84 was removed limitter.
For example,
Ki84-Ib(otu type) recorded 660km/h in Japan.
But,@this is private value. :D

This is same on N1K2-J's engine "homare type21(1990hp)", too.
But, I think AH's N1K2-J is reflected it.

I thiink ,TAIU value is removeing limitter Engine value.

TAIU-SWPA's Japanese Plane at Clark field  is J2M3 Raiden(Jack),too.


sorry poor english.

I want J2M3 Raiden!!!!!!!!!
