Is there a plane from...

[Ruah]

hmmmmm......thats not what I was told

 

KI's are subject to a similar expectation over-estimation in terms of what planes could and could not do - Yak9U - Yak3 comparisons are also equally funky as to really 'how' the 3 is better.

Likewise, the up-gunned 'specialized bomber killer' versions were simply up-gunned and struts and parts were moved around inside the frame, often by simply removing large parts of the internal metal structure, wooden pannels and the likes to force guns in - it was well known that there were large problems in testing with wings folding under g's and at high speed - the version we have is basically the best version.

If anything, Nakajima was adapting the KI 84 or the type 4 model to become lighter with the KI 116 which used the Mitsubishi HA 33 re-designated Ha-112-I  engine (1,500HP) and was built in Manchuria - it was slightly slower then the 84, but it was a lot lighter, climbed better, turned and rolled faster than the 84 - it only suffered in range and top speed/altitude.

The KI 84 (KI disamb. frame - Kidouki) of all versions used the HA 45 - 21 (HA disamb. engine - hatsudo ki) which had 1,825 HP.

There are even unarmed tokko tai versions and so on.  .  .  But the 2 cannon KI 84 was widely considered the best.

the 4 cannon KI was not any faster and probably suffered because of the added weight and modification to the strut to accommodate the bullets and extra cannon - it also never had the power to get high enough to kill bombers so the project focused more energy on a ultra light simple version which would be used for Kamikaze attacks and the standard version which was already deemed good enough for escorting kamikaze pilots - they built them side by side at nakajima.

Sorry to differ with you my friend but you are proceeding under a false assumption. The 4 cannon Otsu would be slightly lighter and more powerful than Aces High's Ki-84 because the Otsu is not based on our model.

I can write a synopsis later, if needed.

Be careful not to mix in the 'Emergency Production' solutions which have more to do with being able to make an aircraft at all rather than as a designed performance improvement.

I would suggest focussing on the first four models produced.

The second best version, imho...

Not that, again...

The Ki-84-II engine was unreliable and never made full power. It was de-rated to run exactly at the same power rating as the Ha-45-21. There was no power increase and no speed improvement. Whether there was a weight change is one matter, but your claims about the engines have been covered in other threads and are wrong.

A Baka might add a little fun to the mix.

Unless I am mistaken, the Ha-45-21 is the more powerful engine in question.  Ours has a Ha-45-18, no?

If Ink gets a 4 cannon KI I'm going to quit.

just like the 4 cannon spit any heavier guns are going to impact on performance.

[Bruv119]

not like the ki-84 isn't a spit 16 in drag already now you want tiffie hitting power? it's crazy I tell you.  Perk it!!!

From what has been posted here, the Ki-84-I-Otsu weighed a bit less than the Ki-84-I-Ko that we have due to other changes.

People seem to prefer making assumptions rather than to actually read the explanations of people who have spent considerable time and resources researching the literature with academic methodology.

By the way I am not requesting the Otsu but rather observing that if we did get it there would be little point in upping the Ki-84 we have now.

Spit dweeb! 

If it is out-accelerated by a Spixteen, out-climbed by a Spixteen, out-dived by a Spixteen, out-turned by a Spixteen and the Spixteen isn't perked then on what grounds should the Otsu be perked?

nnnn?
our Ki-84 have Ha-45Toku(limit version of Ha45-21)

-----------------------------------------------------------
if someone want to know Ki84's story.plz read.
Ha45 have problems of Carburetor.
Temperature was different every Cylinder,
it's like a some Cylinder were over heated but, other Cylinder were no problem.

IJA and IJN gave limit to Boost of HA45-21
(IJA called "Ha-45Toku(Toku mean is Special. I think it is like a SE of RADEON xxxx "SE",GeForce xxx "SE")".
It was possible HA45-21 get 500mmHg boost in plan,
but, Ki84 and N1K2-J pilots used until 400mmHg.
Ha45-21 get only 1800HP by 400mmHg.
(2000HP by 500mmHg)
It was like a Jumo213E's Supercharger,Ta152 pilots used only first stage of Supercharger.

but TAIC didn't know such Ha45-21's limit,
and may be you know, Ki84 got excellent max speed in Philippines.

and some sq in japan,they tried cut of limit sometimes.
some pilots reported "we could use 650km/h or 660km/h if engine status was good."
of course this case was not formal.
Nobody know, Ki84 got over 650km/h in Japan exactly....


sorry poor english.

[Pkun]

excuse me . I want to write story of Ki84-II, too.

Plan "Ki84-II" was changing engine to Ha45-23 or Ha45-25.
Ha45-23 and Ha45-25 are models, change to Fuel injection from Ha45-21's carburetor.

This will resolve Ha45's Knocking problems.
IJA admitted ,
Exactly supply fuel to Engine's piston is most important for normal driving Ki84 without hi octane fuel.
Ki84-II was answer it.

may be Ki84-II will be reliable, but Ki84-II was just plan,
and Ha45-23 and 25 was testing in end of war.

Ha45-23 and 25 was 2000HP.
may be Ki84-II's max speed will be same Ki84-I in phillipines.
But arms will be change from 12.7mm x2 20mmx2 to 20mm x4.

ummm it is little bit lower than Ki84-I's it in phillipines?



sorry poor english.

[Karnak]

Thanks for the information, pkun.

Your English is good enough to get the data through, and far, far better than the vast majority of our Japanese is.
