Hello, everyone. It is my first post.

I am researching Japanese aircrafts' performance and these data were collected from National Diet Library, library of Difense Ministry and National Archives of Japan (and netsurfing XD). If you are interested in Japanese planes' actual flight performance test, please visit my website.
I hope you guys enjoy it.

i dont really trust TAIC that much. Ki-61-II , J2M2, J2M3, Ki-43-II, A6M2, flight performance is utterly wrong and even the Ki-84 taic is just calculated with incorrect Ha-45-21 power curve.

warbirdperformance,

1. I see the moderator needed to remove part of your post. If you are
not able to post the site on this thread, I would very much appreciate
you sending me a PM with the information.

2. What aircraft is the information for, posted in your Post #3?

Laurelix and all,
In my opinion the information published in the TAIC reports is arguably
the best overall information presently available to us on the war emergency
performance of "well tuned" Japanese aircraft using a good 92 octane fuel.
It is true that late in the Pacific war the Japanese were forced to use a
tree sap fuel of 85-87 octane rating.

I have read somewhere that the IJNAF did have 100 octane that they used
for test aircraft.

I have found that you do have to be patient and willing to revise (correct)
or update new information when searching through the TAIC reports.
For instance, I only had the December 1944 / March 1945 test reports
of the Ki.43-II for the longest time. They listed max. speed as 347 mph./
20,000 ft. and max. climb rate at 3,590 fpm./8,000 ft. About a year ago I
came across the May 1945 (revised) report stating max. speed as 333 mph./
19,100 ft. and max. climb at 3,365 fpm./8,000ft.
The May 1945 test report 107A of the N1K1-J lists the aircraft as low-wing
monoplane. Max. speed is listed as 416 mph./19,000 ft. I believe this is the
report for the N1K2-J. The March 1945 report lists the aircraft as a low-mid-
wing monoplane.

japanese manuals state the performance at 92 octane. plus TAIC is just a calculation

From what I have read, Japanese manuals state military power performance w/92 octane
not WEP.

Sorry, it was a self-promotion. But, I thought it was the easiest way to bigin discussion about Japanse planes performance.

The picture I attached was for Ki-61 prototype's actual flight test data translated by Allied force. Original one is written in Japanese language but US captured it somewhere in front line and translated into English.

As far as I know, almost all Japanese planes during WW2 used 91-92 octane gas (except trainer and transporter). But some engines like Mamori required 95 octane gas for take-off rating.
There was 100 octane gasoline's stock but it was a very limited number and used to test captured plane like P-51.

 

[warbirdperformance]

Also, Japanese water-injection was a substitution for 100 octane, so it used for military power rating(jpn:公称馬力) and lasts 30 minutes, not for WEP.

Welcome aboard

I especially enjoyed your article on the Silver Spitfire and was pleased to see the reason it has not moved for almost a month was that it is on display at the museum. A great article - even after being sometimes mis-translated by a couple of web translation services.

Your site will be visited again regularly by me
