How to FW 190 A8?


Recommended Posts

Hi all!

 

Today I had my first time in Focke Wulf 190 A8 and I would like to do better that it can do.

 

In the technical specifications is writed that we have just 3 minutes with emergency power: 2700 RPM, 1.42 ata, but in description we have "There is an additional emergency engine mode system installed. When it is engaged, the first supercharger gear pressure increases to 1.58 ATA and the second gear pressure to 1.65 ATA, the time limit is 10 minutes. This system is turned on by the engine boost command and works only when the throttle is set to 100%, automatic propeller pitch system is engaged and the altitude is lower than critical altitude for a given supercharger gear."

 

So, how much time we have in fact in throttle at 100%?

 

Any tips will be appreciated!!

You should use 100% with boost, it lasts 10 minutes. If you don't activate it you have 3 min with less power, so no reason to not use it really.

Could i use it 3 times (3 minutes, max throttle, engine boost)?

He's saying you can run it 10 minutes straight when you switch the boost on at 100%.

 

3 minutes is 100% without the boost on.

How much time is needed to use it again?

How to measure this recharges?

 


It's around 15 minutes in combat or continuous if you spent the whole 10 minutes. If you use less it would recharge quicker I guess. The only way to tell is via technochat but in servers this message doesn't appear.

Wait till the cooling is fixed

Precisely.

 

Currently you're better off flying an A5. The obligatory wide open cowl flaps on the A8 create so much drag that its boost becomes a moot point.

Boost works for 10 minutes but 2 things: 1st you need to use the button for boost to activate it and it works by injecting extra fuel (EDIT: Extra air from the supercharger) into the engine and is limited by your fuel reserves (uses a lot more fuel). 2nd it only works at certain altitudes at the low end of the A8 supercharger range for gear 1 and gear 2. Since the 190 changes supercharger gears automatically with altitude without pilot input this means that even with the boast button activated the system only works around 1k and lower for gear 1 (ballpark) and then again around 3k to 4.5k for gear 2 (again ballpark) best way to check is that your manifold pressure is above the 1.42 ata that you get on regular full emergancy power (no boost). With the boost activated at the right altitude range the A8 will give signifiant extra power (1.5-1.7 ata) for around 10 minutes before engine damage. If not at the right altitude the boost will activate but do nothing and only give around 3 minutes of regular emergancy power (1.42ata) before engine damage.

For level flight and combat, cowls can be kept around 50% Using this with the boost makes you the current fastest plane on the deck (not including K4) for 10 minutes (in a straight line not climbing) you will outrun all current allied planes in a level deck race in default fighter configuuration. For sustained climb cowls need to be around 80% open on a normal warm map. (Might be able to play around with this). 

Important to note: by default the A8 carries over 100 liters more fuel then the A3 and A5 reducing this load to what you would have in the A3 and A5 greatly improves handeling.

By 1K you do mean 1000 meters correct?

Correct. Now i've never really taken the A8 above 4500m (it climbs pretty slow) so I don't know what altitude the system stops working at for the second supercharger gear but i know that between 3000m and 2000m the system doesn't work because it's in the critical altitude range for gear 1

With boost enabled and at altitudes that the engine is unable to operate for longer than 3minutes, is fuel consumption back to normal? 

 

Is the boost button just a 'permit' operation if conditions are correct, or does it run rich regardless? One would assume that if the engine is only lasting 3minutes it is the former?

Hard to say. Can't find that information on the C3 injection system (Edit: not actually C3 system. Works differently, but similar results). I would assume that due to the automation of the Kommandogerat system. That it is just a permit operation.

I may be wrong, but the A8 boost does not use C3 injection. This is a different A5 boost system

Yes looking into it more you are correct. While they were able to get later versions of the C3 in the A5 to work like the system in the A8 in that you could use it in both low ends of each supercharger gear. The A8 does use a different system but the results are similar. More power and higher fuel consumption. Sorry for the error

It's fine. While the A5 climbs better and is a little more nimble, the A8 is faster even with the heating issue and super heavily armed even with just the default 4 MG151/20 and 2 MG131. It's a monster

Okay, understood

But as it climb slowly, it will consume a lot of fuel (time to climb), no?

In a A3, usually I flight around ~6k or 7k (independet of the map), but in BOB 5k is now "deck", so, I never want to stay below 6k. Said that, isn't important to take off with full fuel tank? (My prefered server is KOTA where the targets are far from AF)

 

Thank you a lot for your time!

 

Regards!

I would like to have A5 (because I love 190), obviously, but it's okay, I don't mind.

Is A8 faster in a straight line in all altitude (50% cowl flaps - continuous/combat mode) than A5 and A3?

How to better climbing with it (I learned that is needed to be 80% cowl flaps! but which A.T.A. and speed)?

Quick question do you guys remove the MG's for better performance?

I don't do this because to do it is needed to replace with armor plate in fuselage that it have near the same weight (if I don't be wrong).
So, I prefer to be more lethal.

Ahh at 6k things are difficult for the 190 A8 and at those altitudes the P-47 and Spit have better performance. I usually don't fly any of the A series above 5k and usually stick around 3k to 4.5k,

but usually that is because i'm escorting low flying 110s or protecting ground targets, and really your most effective at doing that at 3k (perfect height to dive on something on the deck, have lots of speed but still have authority in the controls). Plus at that height you are able to dive to over 800kph before you hit the deck so it's a perfect height to escape anything that is attacking you from above. Even in KOTA a lot of fights are still under 3k and on the deck.

 

In answer to your questions yes as long as you have fuel, you can keep the boost going for 10 minutes at a time before you risk engine damage. You'll want to rest the engine with serveral minutes of regular continuous power 1.2 ata between uses or you'll risk damaging the engine. 

 

I still find climbing at full combat (1.32ata) with 80 to 85% cowls open ( depending on how hot the map is) at around 300kph is the best your going to get for sustained clim. I only use the boost when fighting or if i'm trying to disengage.

 

As for this distances and fuel even if you take the fuel load that is in the A5 of 524 lites rather then the 639 of the A8 you still will have more then enough fuel. It's personal preferance though each having advantages and disadvantages.

 

Cowls should be opened and closed depending on the situation if I want max speed I keep them fully closed for a minute to help accellerate. Then open them to 60-75% to cool the engine back down.

 

My prefered tactic when using the 190 A series is to dive on something in a more or less straight line. Kill it in one pass with only the slightest bit of turning to get lead (maybe 20-30 degrees from the initial heading) if I can't get the target I continue on through straight maintaining speed. That keeps you safe so you can the assess the situation. If i have energy advantage and i'm clear i'll try for another pass. As soon as i'm at an equal energy state with any fighter i'm attacking i'll disengage.

I don't want to be seen by enemies, so i try to flight high and bh.

I hate turn against Reds, so i want to minimize the chances of they seen me and the chances that they be above me (it's inimaginary to me). When i'm with co-alt and/or co-energy I get out from there.

But I got your point.

Thank you again for all your words!
