Fw190-D9 Turn Times?

[Vermillion]

Does anyone have any good data on 360 degree turn times for the Dora?

Niklas? Funked? Wells? Anyone.... ?

Thanks

[wells]

no test data...best I can do is a theoretical figure extrapolated from A5 test data for stall speed (CLmax).  See Funked's data...

If the plane weighs 4270 kg with a wing area of 18.3 sq m and CLmax = 1.4, a 3.0g turn at 200 mph ias gives a turn radius of 290m and a turn time of 20-21s at sea level (without wep = 1776 hp or 1800 PS).  I don't think the AH Dora even puts out 1776 hp without WEP though.  It appears to be only *climb power*, so 1580 hp (1600 PS).  In that case, 2.7G at 190 mph ias gives a turn time of 21-22s.  Prop efficiency is about 75%.

I tested 22.8s and 22.3s for 360 deg sustained turns at 200'.

Hum... going on my personal experience.  At 200 mph, the Dora will do a 360 degree turn in about 4 and a half minutes, with a radius of about 3 kilometers.  Gets a little better with speed though.

Urch you are a little off my last test showed it at being closer to 5 minutes, and 3.5 kilometers, but then again I was doing the bext speed for turning in it.  Dunno when a lanc can turna tighter circle then it who knows maybe it really is a buff?

Urchin,

Hyperbole like that is why people don't take you seriously. When you make utterly rediclules statements such as these it makes people want to mock you. It sounds like a persecution complex based on the desire to feel persecuted.

I know you like LW aircraft. I know the LW planeset doesn't include the best aircraft in all roles. Tough. What it does include are some of the best, and the best, fighters in AH.  The Me262A-1 is, hands down, bar none, the best fighter in the game. The Bf109G-10, Fw190D-9 and Ta152H-1 are all among the best fighters in AH. So what if the Ta152H-1 is rare in AH, you can fly one whenever you want to. What does it matter if very few other people choose to fly it? This isn't "Ta152s High".

If you post rational statements you'll be taken a lot more seriously. We know you have an agenda, but if you balance that agenda with reality you'll get a much more favorable response. We don't care if people have an agenda, almost everybody here has one, we care about people making constant side references to being victims. It gets old.

I'd suggest that you change your sig to something reasonable as the Ta152H-1 is already in AH. Having that statement in your sig makes you seem even more unreasonable.  I'd suggest something useful like "Bring the Me410B-2 to AH" or "Bring the Ju188A-2 to AH".

Lol, Karnak.  I'm sorry you took that seriously.  It was a joke.   I KNOW the 190's didnt turn well in real life, I don't have a problem with them not turning well in the game either.  

Doras actually one of the top 3 unperked planes we have in the set, in my opinion.

[Wotan]

lol check his fighter scores he dont need to be told how good the planes are.

Someone aint gettin enough sleep........

I did some extensive tests on AH D9 turning performance.

The following data is for WEP, 100% fuel, 2k alt (+/i 200 feet), the turn was flow at highest possible G-Load (2,7-2,8G, and i constantly heard the stall buzzer, so i really rode on the edge of a stall   ), it is the maximum substained turn u can get in the AH D9. I flew multiple circle (aobut 5-7 complete 360s and timed the turns in which the alt was the most constanst.

time for 3 360° turns about 1:10.5
time for 1 180° turns about 0:23.5

turnrate is about 15,3°s

speed 208-210 mph IAS (sry not exactly but the gauge is not the best     )

with a fellow from Hamburg i am doing some calculations on D9 turning performance, so far the following data was found:

both birds at 4230kg (or 4270kg, have to look at home for that)and at sea level

1900PS: 15,6°/s turnrate or 0:23.08 for 360°  @205mph

2140PS: 16,4°/s turnrate or 0:21.95 for  360°  @213mph

so far the calculations nearly complete, we try to figure out the last details, but they wont have much impact on the data we have yet.


A little addition, we compared the data with the AH D9, and from everythin we found, the bird is a 1900PS maschine, that is funny cause we should have a 2140PS MW50 D9, because the aux-tank is missing. The Aux-tank was replaced through the MW50 installation.

This is btw one of the things we try to figure out, how and which engine boost settings were actually giving what power. There is sofar a little uncertainty about the speed curves, especially if u compare em with the power development curves of the JUMO213A.
But we are working on it.

Add in: for the calculations, we relly on original FW documents, so far about 98% data are coming from them. Only for the prop efficiency we dont have original documents yet. So if anyone has em, plz drop me a private message.

Naudet, would you happen to have turning information like that for the 190A8 we have in Aces High?  

How detailed do you get in studying these things anyway?  Could you tell me how the 30mm loadout affects turning (vs. the 4x20mm loadout)?  

I *THINK* the 190A8 turns slightly worse (in a sustained turning circle), but that is only because I KNOW the P-51 will outturn one given a long enough turn at around 200mph on the deck.  I've never had the opportunity to get in a circle-fight with a P-51 in a Dora, but I think it would do better since it is lighter and has more horsepower than the A8 does.

[Naudet]

Sry Urchin so far we only did calculations on the D9, and also tests on the D9.

For this one plane it took about 4-5 month now.

But at the beginning we did a rough calculation about A8.

In normal config it was about 0.3°/s below the 1900PS D9 if i remember right.


Edit: i did very few circle fights with P51, they still have an edge over the D9. Especially when they fly under 200mph IAS. And i am by far no newbie in the D9, so turning at max degree at low speed is not that difficult for me.

screw it, not worth getting worked up about.

Urchin,

I do fly all of those aircraft, including the Ta152 once in a while.

I agree that on the deck it is not a great fighter, but if I'm planning on being on the deck I don't fly it, I'll grab an Fw190D-9.

Why should you fly it?  Because you feel like it at the time.  That is why I fly it when I fly it. If you have the points to fly it, why care about its absolute power relationship to other aircraft.  You fly it because you want to fly it.

You shold tell me to stop lobbying for a faster Spitfire?  That's kinda funny because I'm not lobbying for a faster Spitfire.  It is true that I did in the past, but I changed my opinion long ago.  If a faster Spit is added as a perk plane I wouldn't cry about it, but there are many other aircraft that I would rather see.

[Apar1]

Naudet, S!

Nice job.

Will the data be available on a website?

 

[Naudet]

I will post the data in this BB when all calculations are done.

From what i know neither my companion in Hamburg nor i feature a personal website, and so the it might not be presentet on one. Also some of the documents we use are not for use on a public website, so a site would be quite incomplete without em.

AH   FW 190 D ,, dora ,, is peace of crap
but the pilots who fly them are avesame !!!  


i cant fly well dora
