Question for Pyro

[wells]

Should the Fw-190A8 have MW50 boost?

[juzz]

Hi. I am someone other than PYRO. But yes, the Fw190A-8 should indeed have MW50. The AUX fuel tank, should actually be the 115l MW50 tank.

Could or should?  Could yes, should is a philosphical question.  From what I've seen, it appears that the aux fuel tank was the norm.

Thanks,

Was just wonderin' what you thought about that.

MW 50 should be just another load out option. Let the players decide wether it's more usefull to have MW 50 or the extra fuel.

That's what we have with the gun load outs at the moment, there is unlimited supply of WGr.21s, MK 108s and so on. The configuration Fw 190s fly in the AH arena is determined solely by AH arena's environment and not WWII environment as far as guns/bombs are concerned.

How about choices of either:

1.MW50
2.GM-1
3.Extra fuel

For the Fw190A-8 and Bf109G-10.

Btw, any Fw190 from A-4 could have had MW50...

[Hristo]

Yes, please !! Make a choice of GM 1/MW 50 for G-10 (as well as 190, if it had it). Also, was there 109F-4 version with GM-1 available ?

Imagine that

I think this is a good idea, and I'm not even a Luftwaffe pilot typically.

Of course I am still waiting for the P-63 KingCobra.... hint hint.

hello
May be it can help
All the info bellow is coming from original document not from books)
the A8 was fitted with the BMw801D2 production kit F 600 (this is a power egg)
and by mid July those were gradually replaced by BMW801 TU (kit f 9-8801-U). This is a power egg as well

Both of those engines were using a petrol injection in in the blower. That was achieved by bleeding the airline in the compressor between the between the fuel mixture chamber and the boost pressure regulator.
That was only usable at max rpm 2700 in low and high compressor gear.
To activate it you have to depress a button in the front panel in the cockpit.
with the F600 (bmw801d2)the pressure in the cylinder increased from 1.42 to 1.58 (low gear of the supercharger) or 1.65 (high gear)
it was usable for 10 minute in a row and up to critical altitude.
That it was the same for the TU,the usage being longer because of a bigger oil tank and a bigger fan.
That is known as "increased emergency performances"

So up to here no  MW50 nor GM1.
Was the GM1 used ? more than probably, the Fw A8 manual mentioned it, i have seen the flight test and there is some combat report.
This was a simple kit to install
I can not tell to  what extend but it is very probable that it was used in a FW190.

For the MW50
This is a totally different story...
i have found evidences that it was tested by BMW (on the BMW801 D,J,Q,T,S,E,F) and was even tested on planes.
The trouble is i was not able to find any confirmation or hint of operational use.
There is a FW document (cover your arse type) from 4-jan-45 asking for information and reporting problems to BMW on how to install a less complex high pressure MW50. It says that they can not use the existing MW50 dispositive for that purpose. It leads to believe that the MW50 was used with the BMW801 D, TU, TH and TS.

That's all for me if any one as other info please let me know....

Good info weretiger!  I agree that petrol injection should at least be there, in which case the engine puts out 1870-1970 hp.  Speed at sea level rose to 360 mph with this system.  Pyro?

[weretiger]

hum...
the charts (copy orignal charts)
i have gave A8  (A8/R2)
350 (350) @ SL
and 360 (358) @ 2000 Ft
358 (356) @ 5000 ft

all that with 2 mg 131 (475 rnds per guns)and 2 Mg 151(250 runs)+ 2Mg 151 (140 rnds) the back seat tank and without ETC 501, for the A8.

the same for the A8/r2 but with 2 Mk 108 and 55 rnd instead of the 2 mg 151 and 140 rnds)
the etc 501 reduces the speed by 7.5 mph under 20 k
and by 9.5 above.
the etc 504  was more efficient and it was about 5 mph under 20k and 7.5 above
I hope it helps

hristo

as far as i can tell the
Me 109
e7z
E8
F2 z
F4 r1 (i beleive that the uk had a speciemen of that plane to study the gm1)
used GM1

After it is more complicated as the engines changed quite a lot.
for a his altitued interceptor/ reco
Gm1 would have been used.
Unless you used and engine type bd605 AS
where Using Gm1 did not make sense as the rated altitude of the as was around 30 k (wich lead to the asm with Mw50 injection).
I hope it helps.

I will look in my book for more detail on the g vesion

[wells]

weretiger,

Are those speeds using petrol injection?  Also, what was the typical weight of an A8 with 2 mg131's and 4 151's?

Ok, now I am really  

You guys are saying that the MW50 wasn't used on the 190A Series ??

I thought that the difference between the 190A3 and the 190A4 was the addition of MW50.

Now I realize that GM1 was tested on the BMW 801D-2, was found to unsatisfactory, and was normally not fitted.

But I thought the MW50 was used extensively from the A4 onward thru the A Series.

Some more numbers for you guys, from Focke-Wulf FW190 (my favorite 190 book), by Robert Grinsell & Rikyu Watanabe, ISBN 0 7106 0032 1

Data for the BMW 801D-2 (Engine only)
Takeoff & Emergency Power: 1700 hp at 2,700 rpm
Climbing Power: 1500 hp at 2400 rpm
Maximum Power: 1440 hp at 18,200ft (5700 m)
Compression Ratio: 7.22:1
High Supercharge Ratio: 8.31:1
Low Supercharge Ratio: 5.31:1
Dry Weight: 2321 lbs

There are alot more tabular data on speed (without,and with MW50/GM1) and climb for the A8/D9/and Ta152 if anyone is interested.

HOLY ####!!!!  

The Ta152 could do
465 mph at 29,860 ft (9100m) with MW50
or
472 mph at 41,010 ft (12500m) with GM1
and had a service ceiling of 48,550 ft

Wow !! That sure would solve those stratospheric B-17's
