bf 109-g6/u4?

[gyrene81]

i just ran across a pilot manual on the 109-g6/u4...and got curious...basic info i have found thus far shows it had a 30mm hub cannon instead of the 20mm...and the same engine as the g14...now it has me wondering if this was the precursor to the g14 and k4??? 

does anyone have more info on this model? seems it wasn't a mass production version but from what i've been able to gather, a couple of squadrons had them issued.

As i know, that wasnt a serial production aircraft, but rather a kit installed on the earlyer g-6s in '44, to update the earlyer models to the g-14 standards. Not all the tater g-6s had MW50, and not all the MW50 birds had tater tho.
But plz give us the tater availabled on the g-6

G-6 and G-14 are the exact same airframe. The only difference is the engine, hood and the guns. I do know that there were many g-6s with the 'new' hood and the 30mm.

i'd rather have the g6/as personally...even if it was a perked option in the hangar...it was a production model, but i won't go there.

bad thing about rummaging around wwii german documents...i can't read german...all the english stuff shows that g6/u4 as having an upgraded engine too but...

You think the AS engine will give you insane performance? The only difference was in the supercharger, compared to the db-605a used in the standard g-6.
g-6/as had the top speed of 328mph on the deck, but topped out at 408mph at 27k. To compare, our g-6 can do 338 on the deck and about 395 at 21k. The g-10/as could do 415mph at alt, due to the inproved mg-cowling, bad had a poorer performance than the normal g-10 with the db-605d.

/U4 aircraft came from the factory. There are complete production batches of G-6s produced as G-6/U4.

If the G-6/AS would have MW-50 injection the speed would be very close to that of the G-14 on the deck.

debrody...the g6/as had much better performance at high alt than the g6 we have in ah...i believe it had the 605 engine with the 603 super charger (or was that the opposite?)...low alt performance for the standard g6 is ok as it is "balanced"...but it would be more than nice to have a g6 that could do more than 250mph ias at 28k...if you have ever taken one that high in ah would would notice it kinda flops around like a fish out of water.

Here's one listing on the G-6/U4s produced. It's from Hannu Valtonen's book MESSERSCHMITT BF 109 JA SAKSAN SOTATALOUS.

WNr. 20000-20800---------85 U4s, 06.1943-08.1943
WNr. 440000-442099-----1419 U4s, 09.1943-08.1944
WNr. 510600-510999------130 U4s, 08.1944-10.1944

lol  the hungarians got the /u4 upgrade as a kit, to modernize their old planes...   i ate the bait, again.
gyrene, 405mph at 27k is much better than 365mph at 27k... MW50 would increase the low alt speed to about 350 or so, then the machine would be quite fast, even in the '44 standards. Here comes the über and (almost) experimental 109  : )

[gyrene81]

   omg debrody...what 109's are you comparing?

i'm just talking about the factory modification on the 109g6 which increased it's service ceiling and made it faster at high alt...using the db605as engine (db605 and supercharger from db603)...nothing "uber"...and far from "experimental"...it would be a mid war unit unlike it's successors the g14 and k4.

some of the /as models had MW50

[Debrody]

g-6 / AS +MW50, before '44??

[gyrene81]

wrong model...the g6/as late 43 was without the mw50 injection system...that accounts for the mediocre low alt performance gain...the mw50 was put in spring 44

[Debrody]

ok, thats midwar, but without the MW50, right?
AS + MW50 is almost experimental, yet awsome combo. Some were built, but wasnt common til late 44

[gyrene81]

that's my understanding from the data i've been able to find...krusty probably has more data than i've been able to put together.
