Fw190 stuff:

[hazed-]

Just some info for anyone trying the 190a5 out in AH:

source 'FOCKEWULF fw190 in Combat' by alfred price.

info was from allied tests of a captured 190a3

Power plant:

BMW 801-d,14 cylinder,2 row radial fitted with two speed supercharger giving the best performance at 9,000 and 18,000 ft.Between 5000 and 8000ft the performance of the engine falls off as it is just below the height where the two-speed super charger comes into operation.Estimated power 1700 HP at maximum power altitude of 18,000ft.

armour plate:
 
The pilot seat is made of 8mm armour plate and in the unprotected gaps behind are fitted shaped strips varying in thickness between 5 and 6 mm.The pilot's head and shoulders are protected by shaped armour plate 13 mm thick and the windscreen is of bulletproof glass 1 and 3/4 inches thick.Both fuel tanks are self sealing.The oil tank,qhich is situated in front of the engine cowling, is protected by a ring of armour plate varying in thickness, and the tank itself is surrounded by a toughened steel ring.

Gun buttons /switches:

The guns are fired  by means of a button on the front of the control column.A small switch at the side of the column enables the pilot to select the following alternatives:
i    MG 17 and MG 151/20 guns
ii   Oerlikon ff 20mm guns
iii  All guns
In addition to this it is possible, by means of cut-out switches which are situated on the starboard side of the cockpit, to fire each pair of guns independantly.

Harmonization:

The harminization ranges for each pair of guns are:
two MG17 guns at 300 metres or 330 yards
two MG 151/20 guns at 450 metres or 490 yards
two Oerlikon FF 20mm guns at 250 metres or 270 yards.

theres loads more info but this snippet has a bit more relevence to AH.Other stuff is about heatng,sighting view,radio, oxygen,enduance etc.


p.s. it would be nice to have this sort of gun selector in AH dont you think?

Hazed, I'm not sure if the A5 had a different firing circuit than the A8, but I would be very suprised.

Look at the information I posted in the 190 Links post from the 190A8 pilots manual, it tells how the firing circuits worked for a 190A8 at least.

http://www.vermin.net/fw190/190-gun-circuit.jpg

Basically you could fire the inner cannons and cowl MG's at the same time (one circuit), or the outter cannons and any gondola's (one circuit), or all of them together (both circuits switched on).

Me and RAM went round and round on this

Estimated power 1700 HP at maximum power altitude of 18,000ft.

1700 Hp at 18000ft ????

Verm, it depended alot on each aircraft, some aircraft had different then the other of the samer version, as stated by a 190 Pilot in that same book Hazed got the info from.
Also, the info Hazed wrote came from the RAF tests of the conducted on a 190 A3 after it had made a landing in Great Britain. Definatly not wrong.

Actually, the one you describe is the exact same as Hazed desribes. Would be nice to have it in AH since we don't.
We have possibility to select weapon, only plane that can do this is the P51D.

verm im only typing whats in the book.I have seen copies of the original RAF documents on the BB before but sorry not sure where.
Mandoble, thats what the book says and also there is reference to the engine they have being underrated, I'll add it:


'performance:

The all round performance of the 190 is good.Only breif performance tests have been carried out and the figures obtained give a maximum speed of apprximately 390 m.p.h. True at 1.42 atmospheres boost, 2,700 r.p.m. at the maximum power altitude of about 18,000ft. All flights at maximum power were carried out for a duration of 2 minutes only.
  There are indications that the engine of this aircraft is de-rated, this being supported by the pilots instruction card found in the cockpit.Further performance tests and engine investigation are to be carried out by the RAE and more definate information will then be available.
  Throughout the trials the engine has been running very roughly and as a result pilots flying the aircraft have little confidence in its reliability.The cause of this roughness has not yet been ascertained but it is thought that it may be due to a bad period of vibration at certain engine speeds which may also affect the injection system.[Later it was discovered that the roughness was due to fouling of the bosch sparking plugs after a short period of runningThe fault was cured by fitting siemens type plugs taken from the BMW 801A engine of a crashed Do217 bomber.]'

so as you can see there may be slight performance or power increases to what was tested.

Also proves the do 217 was around too hehe

Do 217 to AH!!!!

hers the full info on the book:
'focke wulf in combat-alfred price' ISBN 0-7509-2548-5'

[Wilbus]

There is no reason to doubt Alfred Prices sources, specially not since he had direct contact with Kurt Tank and different 190 pilots and 190 test pilots while he wrote the book! The Speed of the A3 was infact quite much better then 390, not quite sure of it but was above 400.

Main production version of 190d-9 seems to be (curve 2), right? With it's top speed of 702-704kmh at 5.5km. (Other fw document for 190d-9 production model lists top speed as 702kmh at 5.7km)



When we look at AH data for 190d-9 we can see top speed is around 685kmh(428mph) at 5.5km.

So my question is....why is FW 190d-9 so much slower here, just curious?

[illo]

Maybe AH 190d-9 engine is rated 1900hp instead of 2100hp?

[Wilbus]

Starting to think that the Jumo engines in AH are badly modelled. Both the 190 D9 with Jumo 213A and the TA152 with Jumo 213 E-1 are both about 15-20Mph slower then they really were.

[MANDOBLE]

Illo, this chart doesnt seem to be for a standar D-9, the chart is for 190D, but no 9 is seen on it.
Even being hardly readable, in weapons you can see 2 Mg131 and 2 MK101 guns (the Mk is clearly visible, perhaps 108 instead 101)??? plus an ETC rack. This configuration would match with 190D-11 equipped with Jumo 213F instead Jumo 213A. In the other hand, flug-motor seems to read 213A for all the curves.

If this is the speed chart of a Mk101/8 armed D9 (using 213A), then you may expect even more mph for a 2x151/20 standar one.

Forgot to say, 213A did more than 2200 hp with MW50 boost at sea level.

[Wilbus]

WEP Speed of a D9 was about 440Mph.

The TA152 was capeble of 472Mph at 41k. That was the H-1 modelled with GM1 and MW50 boost.

The performance AH TA152 has matches the TA152 C with Jumo H-0 engine.

[Furious]

I, for one, do not want the d9 or any FW's (except F8's loadouts) improved.  I do not want to see a LW la7.

...besides the d9 has the worst high speed handling of all the FW's.  (why this is I do not understand, same wings)  Increasing its speed would only help while running and you would be compressed the whole time.

Uhhh...you need some glasses, that's a 151 in the second row.

That's baffled me too Furious, no idea why the Dora would be the worst handling 190 at high speed. The A8 handles much better and compresses later, although they use exactly the same wing.

Mandoble, sry i have to disagree. This is chart for standard d-9. Look 704kmh at 5.5km.

Here are more matching numbers. If you don't still believe i think there are loads more over internet.

Compare speeds to chart. Numbers in brackets are with MW50 boost which is normally fitted in 190d9. Usable for 10min periods with 5min pauses. Without MW50 numbers without brackets should apply.

[illo]

Mandoble above are clearly visible.

Jumo213A
2xmg131
2xmg151/20

Also ETC 504 rack was standard for 190d-9

And previous chart reads mg131, mk151
(i believe which means mg151/20. Mg151 is 15mm, 20mm conversion from mg151(/20) is actully "kanone" caliber . It's misleading that sometimes only mg151 is mentioned when they actually mean mg151/20)
