Pyro, AH's 190A5 SL speed??

[Fishu]

Pst... niklas,  you forgot to mention that A8 also had increased armor in comparison to A5.

In AH A8 is faster than A5 atleast @ SL:
A5: 326/339 mph
A8: 327/349 mph
WEP seems to bring additional speed, why is that?

Hi Vector,

>WEP seems to bring additional speed, why is that?

The BMW801D of the Fw 190A-5 only used 1.42 ata of manifold pressure (as indicated on the above chart), which resulted in a 1740 HP power output for fast flight according to the engine chart the speed chart is referring to.

The BMW801D of the Fw 190A-8 could be run at 1.58 ata at sea level so that it had a higher power output (something like 200 HP more).

That meant the performance incrase from the 1500 HP (fast flight) the BMW801D made at 1.32 ata climb and combat power (at reduced rpm) was greater for the Fw 190A-8 than for the Fw 190A-5, albeit the latter was faster at equal power settings.

By the way, the numbers you posted are the level speeds for the real Fw 190A-8 at 1.32 ata/2400 rpm, 1.42 ata/2700 rpm and 1.58 ata/2700 rpm respectively.

Since the numbers for the real A-5 should be higher at equal power settings, it looks like the A-5 in Aces High doesn't benefit from the aerodynamic advantages Niklas pointed out.

Hi Wingnut,

>Dunno..i gotta say that's the 1st time I remember at least, seeing 90 rounds listed per FF gun.

I've not seen it listed as equipment for the Fw 190 before, either, but there was indeed a 90-round drum magazine for the MG-FF. Exterior dimensions were almost identical to the 60-round drum, so it would have fit into the Focke-Wulf's wings without modification.

(To be precise, it was 5 mm higher and 12 mm longer, but the MG-FF installation had to account for some handling space greater than this difference anyway).

Loaded weight of the 90-round drum was 30.2 kg compared to the 20.3 kg of the 60-round drum, so the combined weight increase was just 19.8 kg.

Geräte-Nr. of the T 90-FF was 102-462 - just in case you'd like to order a pair ;-)

Hi HoHun

Thanks for clarifying the differences between those two.
Btw, I recall you did tests of AH planes turn rates and stated something about you'd been able to do calculations of sustained turn rates too, are you still in the subject?

Hi Vector,

>Btw, I recall you did tests of AH planes turn rates and stated something about you'd been able to do calculations of sustained turn rates too, are you still in the subject?

Mako did the tests, I just tried to help with the evaluation :-)

I'm still working on some calculations, too, using the example of the Fw 190A-8, but I can't get the performance over altitude to match the engine graph properly. Now that I think about it, my calculated graphs match the US test F-TR-1102 better than the Focke-Wulf graphs ...
