Title: Ki-84's Most Absurd Feature
Post by: nrshida on June 10, 2013, 03:26:34 AM
Please do something about the Ki-84's most absurd feature.

If the random detaching of control surfaces at high speed are supposed to model poor manufacture, then at least make the ailerons and elevators detach one at a time. You can hardly imply that Nakajima's quality control was bad enough to cause the pivot points to unwittingly fail completely and yet imply that unconnected sets fail at exactly the same threshold causing pairs to detach together.

I can find nothing in the literature to indicate this was a problem with the real aircraft and have a test report which already shows a Hayate going faster than our fail speed with no problem.

I hate to be the small boy explaining about the Emperor's new clothes, but that opinion is in face more due to modern marketing and manufacturing techniques (which are basically international). German engineering was / is also imperfect, especially in that period.

I don't mind if poor manufacture is modelled, but let's have it modelled equally across the board...

my 190a8, at speed, I pull back and snap BOTH my wing tips, every time, and its made with metal wings!
I mean we get the stall and flip over to the left if we pull back at slow to medium speeds but the wings still break at high speed?
Metal > Fabric!!! Is 190a8's extra weight for nothing or what?!?! Or do they have swimming pools in the back of the plane?
And yeah my 109 wings break too!
Seems 190s have the weight but not the gain from it!

Kurt Tank "built light and strong, keeping stuff simple and accessible for maintenance." <-- said an English Documentary guy.

German engineering was imperfect?
So you're one of those guys that say that the phrase 'German Engineering' is because they invented the icecream scooper thing?

Spitty are supposed to have delicate wings, some say shoot the wings, but they don't break at high speed? German stuff doesn't have the 'luv' its the allied guys that do me thinks!

Perhaps you should consider your transitions or investigate stick scaling. I've never broken a wing off anything.

No I'm one of those guys who has studied the topic extensively. Why don't you read about the foundation of the Bauhaus and just skip through the decades afterwards quickly.

Just for fun, who's quote is this: "After the war is over I'm going to buy a British radio set - then at least I'll own something that has always worked"?



Anyway, back on topic, AH Hayate control surface modelling...

Can we get a few players to do the tests please?
Training arena, 30k field, put plane in dive, get to 'very fast' or some speed, 500mph? and pull back hard!

Half the planes will break, half wont! and its repeatable!
Title: Re: Ki-84's Most Absurd Feature
Post by: nrshida on June 10, 2013, 05:08:56 AM
The planes have different structural limits & I believe that is modelled on data.

Franz repeat your experiment with both harsh stick inputs and then progressive transitions. That would be interesting for you.

That seems to be the problem there isn't a wide range of knowledge on the ki84 personally I think its deeply overmodelled, relative to the rest of the plane set.

Sorry to differ with you Perv, but it might be the case that it is actually undermodelled if you study the literature. I think we have a conglomeration of models, or a performance which half-reflects manufacturing issues.

If the manufacturing issues are a factor I'd like to know why they aren't depicted in other aircraft too.

The control surface random detachment seems like a good place to start.

They most certainly do.  You must never fly anything that isn't German, not even to test it.  The Spitfire Mk XIV folds both entire wings extremely easily.  The other Spits don't fold quite as easily, but they still do.  It is almost like the Spit XIV doesn't have its stronger wing modeled.

As to the metal wings quip, other than the Mossies what in AH doesn't have metal wings?

lmao...too funny i can't even think of what to say that would be understood. there are several cartoon world and real world reasons you don't put the types of aircraft modelled in aces high into steep aoa 500+mph dives and haul back on the stick...i don't suppose the concepts of structural stress, acoustic fatigue and gravitational force came to mind.

Post by: EagleDNY on June 10, 2013, 10:47:12 AM
G-Force is a constant - if you pull huge G's coming out of a dive, you can make the wings fold up on pretty much anything.   The only question becomes whether the monkey at the controls is still conscious when it happens.   

I fly the Ki-84 a lot, so I know of the shed control surfaces feature.  The times I have shed my control surfaces, yes - I have been pushing the speed envelope a bit hard.   I think the problem really is that without a force-feedback on my joystick I have no way to feel when the "flutter" starts.  Maybe a good solution would be to have HTC enable the "stress metal" sound when you get near to the rip speed of any aircraft - then it becomes up to the pilot to ease off a bit.

I have not seen any actual test data that shows this as a "feature" of the Ki-84 either.

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.

Saxman no offence, but I have studied the Hayate extensively. I can give you the Nakajima serial numbers of the two they tested in the Phillipines including which engines they used if you like. I know what power each engine made and on which petrol.

I am not presently campaigning for more power. I am asking for verification that randomly popping off sets of control surfaces is meant to depict poor manufacture and if it is, I suggest they should not pop off in pairs.

The ki84 reminds me of my f1 vs dr1 experiences in the ww1 arena, even flown extremely badly it suffers no real energy loss when its time to go vert  in addition to that I would realistically need 3 passes at a ki before I down it, much like say an f4f.

IN ENGLISH: for gyrene81 since he doesn't seem to understand!
go to training arena, 30k alt 'field' - dive all the planes, TEST...

I did the quick test version with most of the fighter planes, pulled back hard and some planes broke, some not, sometimes compression so it wouldn't but could still do it at speed.
YES there are planes that I COULDNT BREAK THE WINGS... mmmk? <-- English
I'd say 60% did break, and 40% didn't break, this is from probably two years ago tested.
SO UHH, SKIP THE SUPER DUPER SCIENCE!!!
Yes, planes are built differently, but none are from 'reverse engineered UFO super secret technology apparatus'
This said, maybe some planes historically didn't break?

THE IDEA IS THIS... you are at HIGH alt. You have a BOGIE on your SIX.
If you know that your plane can do the pull out thing, and his cant, you MIGHT have the option to... snap his wings!  
Not only save your bacon, but also to get a kill without firing a shot!

Post by: Karnak on June 10, 2013, 08:22:45 PM
Earlier you claimed Spitfire wings didn't break.  That is manifestly false.  Either your test wasn't very good or you didn't do the test you said you did or you lied about Spitfire wings not breaking in AH.

There is no issue with some planes breaking and some not breaking, but if they break when they shouldn't per data, then they ought to be changed.  Doesn't matter if it is an Fw190 or a Spitfire.

Karnak I put a '?' after... different from a '!'
my spitfire comment was a 'question'... THANK YOU for answering! :)
English for you too!  :neener: I'll try to word me questions more'r correctly, sowwy!

Some planes compress and can't pull up?
Others can but break wings?
Yes, some shed parts at speed, pulling back or not! Last I tested, Arado-234 and B29 both BREAKS BOTH ELEVATORS from speed alone!!! <--- No '?' , see Karnak?
While were at it... DIVE A STUKA FROM 14k... all three LANDING GEARS BREAK! <--- stuka transforms to a 'two seater F4u!' Won't happen from 13k, need 14k!!!
Stuka looks neat with gear up, shame they didn't make them this way, a prototype or two aside I think.
Oh, and Ta-152... it can reach a speed that the controls do nothing, even throttle back... 600mph? Plane shaking forever and lawn dart from high alt! (again, was 'quick test' and long ago!)

sooo, to get the achievement of 'landing with no elevators'... up a ki84? or Ar234? B29's also?
Use the Ki-84, other two I know cost too much!

Really Nrshida, I agree that it sux, both at same time, no warning! I'm assuming that HTC did their homework, without bias hopefully!
How else for us to get punished for breaking structurally tested speed limits that were printed in the handbooks?

Post by: gyrene81 on June 10, 2013, 10:12:59 PM
here is some engritsch for you Franz...learn the science. just the fact that you think a 190-a8 shouldn't snap the wings off when you haul back on the stick at 500+mph, especially in a high angle dive, tells me you don't know crap. doesn't even matter what altitude you're at, if the airframe hits the critical speed, things start coming off and it gets worse when you apply opposite force with the control surfaces. they're airplanes, not rockets genius.

The really weird ones from my perspective are the Mosquito Mk VI and Mosquito Mk XVI.  They used the same wing, the stronger wing actually being introduced with the Mk VI, and tail, but the Mk VI loses control surfaces to speed and the Mk XVI does not.

strange...I have never had pieces come off till 500....maybe you pulled back a bit to hard?

What happens for me Ink is that I can fly up to 450 m.p.h. no problem. Above that I have to be very gentle with my inputs or either the rudder, both elevators or both ailerons pop off and what pops off seems to be a random lottery. At 480 they pop off regardless of being neutral or even trimming out of the dive.

I do not use Combat Trim, I don't know if you do Ink, it's the only significant difference I can think of.


Just as a sidenote the AH Hayate has already stiffened up far before this speed and this is historically accurate.

It can be done, no ailerons is easier but it's a bit tedious.

It's a fair point Franz but happens in AH at a speed that we know the evaluation aircraft exceeded. Since it happens consistently one could argue it is the duty of the pilot to avoid it. I very very seldom do this and usually when chasing an opponent who has dived away. It is a defining feature however and dictates how you fight.

My only concern is that I now believe the AH Hayate is a mongrol of different versions (which is understandable), with certain features intended to pseudo-represent the manufacturing issues especially of the later production models. If that is so it isn't fair to only apply it to this type / nation.

 
Karnak, what does the literature say about the Mosquito losing surfaces?

I do leave combat trim on.....never made much of a difference to me..... my elevators are what comes off on their own....and not until 504-505....now thats to say they just pop off  I dont have to pull back...I am sure they would come off sooner if I yanked the stick back.

It seems combat trim on does keep it together for a bit longer.....

honestly though you know as well as I......if you are going above 450 in the KI you are doing it wrong. :rock

I'm not sure if its modeled, but shouldn't parts tearing off have to do with altitude? The air is thinner up there.

Question I ask:  does stuff break at same speed at every alt?
Test with Ki-84? The training arena has fields at different alts - some no actual field but just drops us in the air.

Logical stuff: parts should break at lower speeds at lower alts, and at higher speeds at higher alt?
Microsoft Flightsim: take off in Leer Jet, if hold full throttle at say 1000feet, plane will tear its own engines off almost immediately - get to about 300mph(? not sure been awhile) and the overspeed sounds and lights come on? At 45k alt, we can keep throttle at full all day until the fuel runs out if you like... plane reaches mach .9 about? (1.0 is speed of sound.)  Fast but thin air so parts don't break. Not sure how fast mach .9 is at 45k, been awhile. (not sure of any of these numbers! no quoting me!)

Going to have to disagree with this Gscholz. It is entirely possible for humans to do human things perfectly because they are insular actions that although derive substance from sensory information around it, can be perfectly expressed given the right time and circumstances.

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).

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?

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...   :bhead

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

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.

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...

Howdy, Nrshida.

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.

No one can tell at all from looking at the structure.  You can't tell by eye if a control surface will experience catastrophic flutter at a particular speed.  As one example, there was a fatal crash at Reno Air Races a while back where an unlimited racer (based on P-51 but with a Learjet horizontal stab) flew through the wake of another racer, which triggered flutter on the tail, which then failed.  A Learjet tail is plenty strong and able of course to fly at very high speeds usually, but the aerodynamics were such that on the P-51, it could get into a regime where flutter could be triggered and result in catastrophic failure.  Not only would you not see that coming by looking at the structure of the Learjet tail or knowing that it routinely flew at near Mach 1, but the designers and crew (much more experienced in building and modifying high-speed unlimited-class racing aircraft than you or I) obviously didn't.  There are examples of very capable aircraft designers not knowing this based on structure or design, either, and only knowing it once seeing it happen in test flights.

Quote

They can.  Flutter can happen for both at about the same time.  In fact, since they are nearly identical in design, one's first thought should be that both ailerons should could very well experience flutter at about the same time.  Here are a couple videos of planes suffering failure to both left and right wings and/or both left and right wingtips at the about the same time:

There are two aspects here.  One is that you say this, but what is the situation and what is the reference?  Did one person dive a Ki-84 to 550 mph and recover without damage to the aircraft while several other references state that it comes apart at 550?  Also, failures in real life are stochastic things.  There are some P-38's that tore apart in terminal-velocity dives and many P-38's that didn't.  To model a P-38, you then need to choose whichever mode is more typical, or if you have enough data statistically, you could model it as a random process of failure of 1 in N terminal-velocity dives, but you'd need a lot more statistics than are likely available to judge that and to set N correctly.

Lets say you'd be forced to use higher grade than what you normally had, without MAP change, would you gain the power? Nope...



Japanese aircraft were generally limited to fuel with an octane rating of 88 or less.

Myth. They had sufficient quantities of 88 and 92 avgas. Their aircraft engines were designed to run on these grades of fuel.


When tested using 115/145 avgas, the full power of the engine was available and there was a significant increase in speed.

Well, KI-84 wasn't tested with 115/145 avgas. Ki-84 tests at Clark field were done with 92 avgas (plus methanol for WEP). Same fuel Japanese used to fuel their KI-84s. Even if it would be fueled with our higher grade avgas, it wouldn't matter, since no performance enhancing modifications were made on the aircraft.

This was exacerbated by the finish of the aircraft being far better than the typical service aircraft.

Irrelevant. AH does not model maintenance issues.

Hi Brooke,

That comment was directed at those who feel the aircraft should be more fragile to damage from gunfire, not about the surfaces.

I'll watch those videos when possible, I have seen footage of flutter before but my first thought was that a structural failure would unlikely happen to two separate areas exactly at the same time. Are you conjecturing this is the explanation in AH or do you know this is the reason?

No it was the pre-production evaluation aircraft upon which our version is based. I'll fetch the reference for you tomorrow. I can find no mention whatsoever to flutter or detaching surfaces in the literature.

I was wondering if Karnak found evidence for the Mosquito doing the same in the literature? If not then that might be suggestive.

I've never read of the Mosquito losing control surfaces.  The closest I have read of is the skin peeling off due to manufacturing defects, but those instances were always far below maximum allowed speed.  I am aware of at least one Mk XVI that dove to speeds well above the maximum allowed as it tried to escape an Me262.

I don't have any inside knowledge of how or why HTC models things, so anything I post like this is my conjecture.  My thought is that, if one aileron is experiencing flutter, the other probably is within a very small speed range of doing the same.  Given that failure in AH is often when the plane's speed is increasing, it would seem to me that both ailerons would experience flutter about the same time and thus fail about the same time.

As most of us don't have the manuals and information on the internet can be flawed, we can really just speculate. My 2 cents having a pilot licence is this;

All aircraft have a Vne:

 a maximum allowed speed, now im guessing most if not all ww2 pilots had ground school and were schooled in max speeds,maximum g load, and dive speeds not as many real pilots would do half the things we do in ah lol. That being said and the fact i like the ki i agree over 450 and ur fighting outside ur element.

I don't mind if poor manufacture is modelled, but let's have it modelled equally across the board...

In the course of history, tribes of Scandinavian origin took over Germany, Britain, France, Italy, Spain, North Africa, and Russia.  Just with respect to Britain, after the Romans, it was taken over by the Angles and the Saxons (Germanic tribes of Scandinavian origin), then later from them by the Normans (of Scandinavian origin).  All tribes or nations historically have had some peak before and after which they were not as dominant, so the argument that at some point a particular tribe or nation was no longer dominant is moot.  The dominant times of the Vikings, Goths, etc. were very dominant.

So after a complete hijacking of the thread....

Flutter.

I think a solution may have already been stated on terms of audible warnings of impending failure of a control surface. With flutter, you would feel the vibration prior to the failure, not just "blink" failure. Disclaimer... I am not an Aero Engineer, but I am an Engineer. It seems to me there would be warning signs prior to the failure. Every airplane being "new" at take off and up to specs.

I quit flying the Ki-84 because of this. For whatever reason I could never figure out the magic speed to not use ailerons during a dive and ended up with a 3 channel airplane.

I lost bost elevators on a 410 yesterday diving on a radar. I was in shallow enough of a dive that the plane naturally pulled out of it. There was no warning or stress sound on the airframe. It actually surprised me.

The question I have for the Aero guys out there in regard to Shida question is:

Given the amount of force a pilot is allowed in AH (60lbs?) on the sick, could they put enough pressure on a non boosted surface to cause it to fail at speed?

Post by: Brooke on June 16, 2013, 01:27:51 PM
Flutter can result in failure very quickly after start of the flutter (so quickly that the pilot can't do anything about it) -- it depends on the aerodynamics and the structure.  It's not due to the pilot exerting control-stick pressure.

Some planes could experience, say, aileron flutter and survive it.  Others didn't.  It depends entirely on the aerodynamics and structure, not just one or the other.  As an engineer, think resonance frequencies, structural failure, etc.

Combat trim will trim nose down to compensate for the increasing speed. Turn off combat trim and set all trim to neutral and try it. You will have problems keeping it in a dive without control input though... Try a shallow inverted dive.

I would explain if it were anyone but you. You aren't interested in discussion, you just want to hear it so you can devalue and dismiss it one piece at a time and impose your opinion on everyone else instead.

All it took to set you off this time was you thinking I was criticizing German engineering, when I refused to explain my comment (which you clearly didn't understand) you immediately resorted to insults: I said nothing about the car industry, nothing about British engineering, mentioned German engineering incidentally & certainly didn't deride Norway.

I'm curious, a few months back you had a parole status. Then Skuzzy said something about how you'd mellowed. Did you get a PNG for your 'pick up the gun' shenanigans in the past?  :D


Anyway now I'm hijacking my own thread  :rofl

I do not use combat trim, I manually trim at a certain speed and if I make a medium or less-than-slo-mo input at > 450 off something pops. I can trim out of a dive with no problem. At 480 things pop off even if I am control neutral.

Flutter doesn't depend on control input, by the way.  It is an aerodynamic instability of the control surface, not a steady-state force because of control-surface deflection.

Back on topic of the Ki-84. Spectacular aircraft that has an .. interesting... flutter issue which doesn't seem to be specifically recorded anywhere IRL (from what I've seen personally).

I've flown the Ki a little (nothing compared to Ink or nrshida) and made a personal note: Don't get the Ki over 400.. The Ki feels like a spit/K4 hybrid that excels at low speeds (like the spit and k4) but dislikes high speed to a much greater degree than the spit and k4.

I was usually too low and surrounded by too many red guys to get fast enough to rip things off, but it did happen a few times :old:

It certainly doesn't feel right to always lose both ailerons/elevators simultaneously at exactly X speed with Y  G-load on cue ... every time :headscratch:

the newer models of the mossie and hurricane,  the A20 when loaded in a steep dive all do this.

I think people see images of the jousting armor or the late armor meant to deal with early guns where the knight had to be hoisted onto his horse and think that is what medieval battle armor was like.  Samurai armor is fairly light for its strength.

Not quite true.  The point on a katana is very well shaped for punching through armor.

You're also grossly underselling the Japanese armor.

While the katana was not the mythic cutting weapon it is often portrayed as it was far more effective than just against pajamas as you dismissively put it.

Last time I was in a combat area I was carrying hundreds of pounds of gear and armour and needed a bunch of guys to help me up if I fell.

In actual fact probably around 100lbs of kit, rifle, helmet, body armour and boots. Spare link for the LMG, spare mortar rounds,occasionally link for the GPMG, radio, spare batteries, NVG's, grenades, smoke, water, scran. In actual fact, it was worked out that soldiers carry pretty much the same weight now as the Roman army did, verything has been made lighter and more compact but you end up carrying more crap as a result.

Sure. Our winter backpack alone weighed 70+ pounds. However we didn't fight with all that gear on; we dump it asap and fought with only our combat gear which was perhaps 20 pounds total. Nowadays they have body armor in addition, so it's prolly 30+ pounds total combat gear.

Try closer to 50. The full IOTV with side SAPIs is crazy heavy.

When I was a young 11B in 1/325 AIR, as a team leader my ruck was just a hair over 80 (CLS Bag and Breach Kit). This was the with three days of stuff, and blank, not live ammo. Then kick in the LBE with another 15 lbs or so, your rifle, right at 10, MILES, and a chute, I easily had more on me than I weighed when jumping.  

Now back to the questions .... can flutter be simulated in the game, to give players fair warning before stripping parts. There is an awesome scary video of flutter on live leak of a business jet's wing just going crazy. Very .. Very scary to watch.

Current combat gear:

Dont believe in the Robocop approach? Not sure what this means. The British Army apparently believe in the 'have enough kit to get the job done approach".

Katana was a fine weapon for killing someone wearing a pajama. Large broadswords usually met either proper armor or very thick clothing/furs and a bit more oomph was needed.

I just happend to pop in this thread and read this...

Having worn, built and tested both European and Far East armors (Japanese, in particular) I can tell you that the cloth based armors are incredibly effective and do not interfere with movement as much the European armor does. The one surprising feature of Far East armor I found was it didn't dissipate heat as well as the European metal armors. Probably as much do the layering effect of the Far East armor as much as due to increased conduction of the metal of the European model (even while wearing quilted arming jackets underneath).

Because of armor, the Katana was not the primary weapon of a samurai on the battle field. In real battle, they'd proudly wear their praised katana - and then grab a generic spear (Yari) or one of their polearms, or a big baseball bat to do the real killing. With European swords it depends - the real two handed swords were primary weapon of war, but the ones nick-named "bastard swords" (not a real name at the time) were secondary. Duels in Europe were often fought in full armor.

Samurai also spent a lot of effort learning to be mounted archers, but yes, for melee the yari, naginata and those nasty looking studded clubs were dominant.

The Tachi was really the Japanese sabre of the armour period which was usually carried cutting edge downwards, typically had more length & curvature and more taper and a cutting edge designed to penetrate armour. It is true that was rather down the priority list of weapons but was also wielded from horseback.

The evolution into the Katana, being one of the two part Daisho set, happened in the transition to more 'peaceful era' (if we can call it that). These were carried (and more significantly stored) edge up. This period is the phase were much of the fencing was refined to a Zen activity and also the blades began to be forged and polished as an artform in themselves.
