Ki-84's Most Absurd Feature

[GScholz]

What? 

[2bighorn]

Do keep in mind that most of the test data IIRC comes from post-war testing of captured birds using 100 octane US AvGas. Which the Ki-84 never used. So yeah, of COURSE there's going to be a massive performance difference.

Oh yeah, when I put premium gas in my truck it goes twice as fast...

You told me you drove a scooter??

You don't boost your engine more when running on higher octane fuel? Then why buy premium if your car is rated for lower quality?

I would like to see the ki-84 re-done though,

See lanc, hurri, yaks etc the new models seem to die when hit with a good burst. 

Many times i've cut a ki 84 and it has soaked rounds like a sponge.   

The Ki-84 is an AH v2.00 model.  I don't think it has the damage model irregularities the AH v1.xx models sometimes do.  It is just a fairly tough fighter.

Would you say it is or should be tougher than a jug?

I don't think it is tougher than a P-47.  The P-47 simply gets hit more, and is easier to focus fire on a single area, due to their relative sizes and maneuverabilities.

Your going to love my nuts! 

We're going to make America skinny again, one slap at a time.

I don't think that planes losing parts at high speeds has anything at all to do with modeling poor workmanship.  I think that all planes in AH are modeled as if they were competently built to spec.  I think that it has to do with the fact that some planes have a maximum speed beyond which they have problems, such as structural failures or control flutter leading to failure.  My guess is that HTC has some information on planes indicating speeds at which they get failure or catastrophic flutter.  This is a matter of aerodynamics and structural strength, not just structural strength.  For example, control-surface flutter can result in failure even of very strong structures (even on unlimited-class Reno air racers).

Only in RL, but that's Internet here, I drive whatever I want

The whole point of testing captured enemy planes is to find how it would or should perform when modified to run with higher boost guzzling our quality avgas and not how it actually perform as manufactured and used by adversary...

Oh the naughty military intelligence...   

[GScholz]

Post-war tests... The enemy was no longer relevant.

When we were forced to run 100 LL fuel in our R-1820s, we had to re-index the props and had MAP limitations. This reduced available power, and correspondingly reduced climb and speed (not that we ran at full power very often). Essentially, we were down just over 200 hp. Japanese aircraft were generally limited to fuel with an octane rating of 88 or less. When tested using 115/145 avgas, the full power of the engine was available and there was a significant increase in speed. This was exacerbated by the finish of the aircraft being far better than the typical service aircraft.

Only insofar as all human engineering is imperfect since humans are imperfect. Despite what they wanted the world to believe they were not supermen. However, they were building jet fighters in forest clearings from substandard materials using basic hand tools while under the constant threat of air attack, so cut them some slack.

I think you have misinterpreted what I wrote.


If you look into the structure of this aircraft you can see how it is a little unusual and should have a good deal more integrity than a Spitfire, say. Anyone who has any actual data which implies the AH Hayate is overmodelled I'm sure HTC would love to see it as much as I.

The loss of sets of surfaces can't be modelling flutter as they detach exactly at the same time. Besides the evaluation aircraft went faster than ours does this, without incident.

were there more than one? was more than one test conducted using the same aircraft with the exact same results?

i ask because i've seen "test data" that showed 109s and 190s that went faster than the ones in ah, but there were a lot of variables throughout the tests and the pilots were not hauling on the sticks like we do in cartoon world...
