A8 to fast after update?


Recommended Posts

I think it's still a little bit too slow, it should be able to go at 558 hm/h at sl and some source says more than 560 km/h (without 1.58 ata)

I think the quality of the aircraft can easily change his effieciency

560km/h? Not without 1.58ATA.

Which source does say that?

I managed to do 296 knots in sustained level flight at sea level in the A8 after the last update. Is that to fast? That's only 4 knots slower then the P51D at full mil.

 

I couldn't pass the 525kph barrier (1.41 ATA).. which is very slow for the A-8 anyway.

I think that nothing has changed.

 

1,42ATA, 100% - 2700 RPM

with ext. rack

coolant flaps fully open - 518 kph (one previous DCS build 517 kph, my old test)

coolant flaps fully close - 532 kph (532 kph, from the same like above)

 

the same eng. setting without ext. rack

coolant flaps fully open - 532 kph

coolant flaps fully close - 547 kph

(did not find any older data, lost them...)

 

It seems that fully open coolant flaps have the same drag like external rack, but this is not new.

This one http://www.wwiiaircraftperformance.org/fw190/fw190-a8-25oct44.jpg

And this one says 578 km/h http://www.wwiiaircraftperformance.org/fw190/fw190-a8-12jan44.jpg

 

I don't understand the gap on the graph and why there is a so big gap between graphs with the same plane maybe I forgot something ?

~518 km/h @ 1.3 ata

~535 km/h @ 1.4 ata

 

This is with the ETC501 rack ofcourse.

 

Top speed without the ETC rack was 548 km/h @ 1.42 ata, and 564 km/h @ 1.58/1.65 ata. This is according to the last performance charts dated 12.1.1945, which we therefore must assume are the most accurate.

Thanks! That's why they used other boost systems like GM-1. But it still remains a mystery why it loses power in turns.

Well, 1.58/1.65ATA boost increase and GM-1 would be awesome and make the A8 really strong. But I bet a "DCS Module-Giveaway" that we won't see both in the next 5 years, or at all.

 

It doesn't loose power in a turn.

Because if you loose speed during the turn, the propeller governor has to reduce the prop-pitch, but is just unable to reduce it fast enough during a hard turn, thus lags behind. When you ease the pull, the governor catches up and the rpm is stabilized again.

You can see this effect on every other warbird in DCS.

And you can make it more visible if you switch to manual propeller pitch. Manual prop pitch in the A8, K4 and P-47.

P-51, Spitfire and the Dora don't have manual prop pitch.

Switch to manual, fly a turn where your speed drops and you will see the rpm drop too. During a split s your speed as well as the rpm will increase .

 

And I think AOA change on the prop comes into play aswell, but I don't know how strong the effect is.

I probably mixed your "loosing power" with rpm drop during hard turn.

So what is your problem exactly? Describe it.

Is it easy? No, absolutely not. You have to be veeery gentle and careful with the elevator. It was not my first try. The loops are not perfect.

 

Clean Anton, w/o pylon, full fluel&ammo

 

The Anton is not a dedicated loopingmachine.

 

So, what now?

Thanks for taking the time to test the Anton's looping capabilities. First of all, the loops are not correctly done but skipping this, I asked you to make 2 consecutive loops.. that means when you exit the first loop you must enter the second one and not gain speed flying flat, those are NOT consecutive loops, in other words, the loops should intersect.

Nice, iFoxRomeo now do this 100 times more and you will see.

Hm... My wife will declare me insane, sitting at the pc with the VR-Headset looking up and down for 3 hours.. otoh it might be a good handling training:lol:

Why don't you show us, how you mean it? With an aircraft of choice. Make a few loops the way you described it, then we can compare the Anton to it. Otherwise noone knows, what you mean with

It loses power.. a lot of it, no doubt about it.

Of course it's a wrong behavior, as long as you have common sense and notice that it loses power. You just have to compare it to the other planes IN DCS with comparable or less power to weight ratio.
