109 performance notes

I personally would like to see a 109 variant utilizing the DC605DC - maybe we can talk HT into making the K-6 available.  My Janes is showing that as having an additional 2 30mm gondolas (103's not 108's) and IMHO that with the DB605DC powerplant would make a good "slightly perked" 109 variant.  I'm sure it would cause some "brown trousers" in the bombing ranks.

Agreed, a perked 109 with the DC engine would be nice. The DC was mounted from January 1945 onwards into the 109G-10 and K-4, and a very similiar (identical in output, ie.2000 HP) engine, the DB 605 ASC was put into the 109 G-14/AS. Output was 2000 PS at 1.98ata manifold pressure, which was cleared for service use after trials in late February. There's written documentation from 20th March 1945  for 1.98ata use for the 109Ks/G-10s of four Luftwaffe wings, ie. II and III of JG 27, and III and IV Gruppe of JG 53, altogether possessing ca 150 planes at that time. See my site for details!

At 1.98ata, the 109K did 607 kph at SL, 715 kph at 6000m, initial climb rate was 24.5-25 m/sec.

Hi, gripen and everyone

Yes, Russians tested Bf109G-2. Pls see below results of test in NII VVS.
I also have a speed curve, but do not know how to attach it to this message

Dear ALL

I'm collecting German original tests of Luftwaffe aircrafts
I found some data charts on this forum.
Maybe somebody can add anything new from GL/CE-2 or something like this.
I can exchange for data of Russian aircrafts (Yak, etc.)

As noted above in the same data set there is exactly same speed values for the G-14 dated 13.8.1944 and marked as Rechnung just like all other values from the same date.





Did the Russians actually do the full speed tests?

Sorry for such format
The order of shown numbers is following:
Altitude, m
TAS, km/h (both fop G-2/R6 and G-2)
Vertical speed m/sec (both fop G-2/R6 and G-2)
Climb time, min (both fop G-2/R6 and G-2)
