please adjust the 190A8

[dhyran]

Gentlemen,

look at these Docs!

http://www.wwiiaircraftperformance.org/fw190/fw190a8.html

Level Speed: MPH   /   km/h 
   359 mph at Sea Level    578 at 0 meters 
   405 mph at 18,045'    652 at 5.5 
Climb rate of the "normal Version was 3200 ft/min



Focke-Wulf's Technical description No. 284 Fw 190 A-8 Fighter from 30 November 1944 notes the following:
Increased emergency power: Starting from July 1944 all Fw 190 A-8 aircraft will be equipped with "increased emergency". By overridding the supercharger boost regulator, boost pressures are increased at take-off and emergency power in low supercharger setting from 1,42 ata to 1,58 ata and at the high supercharger setting from 1,42 to 1,65 ata. Thus an increase of speed up to 13.6 mph (22 km/h) is obtained with low supercharger operation and up to 15.5 mph (25 km/h) with high supercharger operation. The maximum operating time for increased emergency is limited to 10 minutes due to thermal reasons.

(Ab Juli 1944 werden sämtliche Flugzeuge der Baureihe Fw 190 A-8 mit "erhöhter Notleistung" ausgerüstet. Durch Eingriff in den Ladedruckregler wird der Ladedruck der Start- und Notleistung im Bodenladerbetrieb von 1,42 ata auf 1,58 ata, im Höhenladerbetrieb von 1,42 ata auf 1,65 ata heraufgesetzt. Hierdurch wird ein Geschwindigkeitsgewinn bis 22 km/h bei Bodenladerbetrieb und bis zu 25 km/h im Höhenladerbetrieb erzielt.; (sich Flugleistungen Bl. 15). Die höchstzulässige Betriebsdauer für erhöhte Notleistung ist aus thermischen Gründen 10 Minuten begrenzt.) 



So please make a review and change back from our current Sturmbock numbers up to the normal 190A8 numbers!

The numbers are right, I never noticed it before, but those are the technical specs for a mid 44 Fw190.

[Skuzzy]

Our speed and climb rate charts are nearly a perfect match to the charts shown.

So what is the specific issue?

[Butcher]

Level Speed: MPH   /   km/h 
   359 mph at Sea Level    578 at 0 meters 
   405 mph at 18,045'    652 at 5.5 
Climb rate of the "normal Version was 3200 ft/mi

Only thing I can gather is our Fw-190a8 does 327mph (no-WEP) speed at sea-level and  349mph (WEP).

So our Fw190 is 10mph slower, otherwise the numbers are almost a match

[Guppy35]

Oh Skuzzy...

How dare you throw a hanging curve like that!?!

Do you have any idea how hard it is to not swing at it?  

[Wmaker]

The A-8 in AH pulls 1.58ata with WEP-setting.

Hi skuzzy,

thanks for your attention

i get at AH Fw-190a8 322mph (no-WEP) speed at sea-level and  345mph (WEP)
but like these Charts show it should be   
   359 mph at Sea Level at sealevel 
   405 mph at 18,045'    652 at 5.5 

climb rate of the "normal Version" was 3200 ft/mi

Only 10 mph, like butcher says, but 10 mph means more acceleration, more E state etc. 

As another part we should review the E drain it got, the 190 had a small surface compared to a 109 spit etc, if you see them lined up one besides another it should retain the E better. But i didn't found numbers but mailed the TWTH Aachen, i know a couple of years ago this University made some calculations about the airsurface of the 190A series

[Skuzzy]

You do realize our charts are generated based on a weight of 9682 pounds (4391 kilograms)?  Slightly heavier than the #1 listed in the performance chart you show and even further apart from the weight of the plane in the climb rate chart.  

I am not an expert here, but that weight difference should make some difference.

[PFactorDave]

Uh oh...  Skuzzy may have just stuck a pointy stick into a hornets nest.

rgr!

but this one shows the different additional Rüstsätze, so choose curve 1 is based on 4300 as the current standard 2*20MG 151 2*20 MG 151 + 2*MG 131
So chososing the AH light setup should bring additional speed, because one 151 gun was 42kg. That means to the current 4391kg you choose, it should bewith the AH light gun package should be 4216kg! That's a huge difference than

Really not trying to.  I am more curious than anything else.  I have no control over these types of things (or most anything actually).  Some of the things I have learned by working here are that there is usually not one set of data which can tell the entire story of any given airframe.  There are usually several sources involved.

I also know everyone here does the best they can to insure the accuracy of the flight models in the game.  It is fascinating to watch how any given flight model is brought to life.


Dhyran, my German is not what it should be (second generation removed) so I have no idea what you just made a reference to.

[Skuzzy]

I understand the columns.  I did not understand "Rüstsätze".

The weight we use is based on a number of things (fuel, ammo loads...).  I cannot specifically state how any given weight is determined but I am pretty certain you cannot just subtract a gun package to determine a base weight or add a gun package to determine another weight.

Again, I am not sure what makes up the weight and I am also not sure how much weight will impact the charts themselves.

"Rüstsätze"/Weapon package kits. For those who want to know.

Interesting,to say the least.



This is a good lesson in how to properly bring a possible issue up. Do it like some jerk, and HT will eat you four breakfast.
