1: The chart you sent me "is" from 8/4-1944, it says that quite clearly – 8.IV.1944.
How common was the use of Roman numerals in German dates? And why just for the month?
That's not the date.
The chart is for an engine which isn't even capable of 1.98ata boost, its a D-2 engine, so it can only be running at 1.8ata.
It is absolutely, categorically, running at 1.98 ata. I really suggest you email Butch for further clarification on this.
1.98ata boost pressure was cleared sometime in December 1944, and it was only cleared for the DC engine.
It wasn't finally cleared until March, but there was a premature clearance in December.
If you look at the chart you 'presented' for the DC/ASC engine, the climb rate is 22m/s at Start u. Notleistung, 'without' MW-50 and at 1.8ata.(Which is 1,725 PS btw)
Not according to my info. Again, email Butch.
Then look at the chart you sent me for the D-2 engine, its 25m/s at Sonder Notleistung 'with' MW-50 at 1.8ata.(1,850 PS)
No, it's at 1.98 ata. Email Butch.
Make a guess on how high a climb rate you think the K-4 has with the DB-605DC engine with 2,000 [email protected], cause considering it has a climb rate of 25m/s with the D-2 engine at 1,850 PS,
No, that's at 1.98 ata. Email Butch. He will be able to give you further supporting information that I can't
Butch has the full report. It is, as far as anyone knows, the only report on the K4 at 1.98 ata. If you want further information, you will only get it by talking to Butch, or one of the people he has sent the report to.
Do you at least agree now that the "3 mins to 5000m" and "6.7 mins to 10,000m" are wrong? That the figures are in fact 6 mins to 5,000m, and 13.5 mins to 10,000m, both at climb and combat power?
