View Full Version : Ta-152 boost problems

Been trying to use the Ta-152 and half the time when I use the boost the engine ends up being damaged and dying. Any tips on how to avoid this? I haven't had this problem with any other planes and the aircraft guide doesn't tell you how to deal with this problem.

Reduce throttle first. Some people say below 100, some below 80, but I usually just zero my throttle completely when engaging and disengaging boost. Probably don't need to, but thats what I do.


Some later 109s will have similar problems. US/Japanes/Russian/Brit planes though, you can engage WEP/Boost/injection systems at any time.

I don't think there's any need to throttle back when you turn the boost off, but otherwise PanzerAce is spot on. It is easy to forget this, especially when you don't fly the late German planes that much. I ended up looking rather silly on a server yesterday, chasing someone with a damaged engine - I think it was something really slow too - most annoying.

The Ta-152 is surprisingly manouvrable at low altitude, but don't expect it to outturn a Spitfire - it won't, as I reminded myself again today - they don't fly as well with a wing shot off. http://forums.ubi.com/images/smilies/53.gif

Just make sure you are below 100% throttle when you engage boost.
For disengaging you can do that at will at any throttle setting.
That is what I do and I don't damage my engine (that works on any MW50 equipped plane BTW).

engage the MW50 at 49% throttle or less, should have no probs then

MW50 up to 6,000m, above that, disengage it (throttle setting irrelevant)

at 9,000m engage GM-1 at 49% throttle or lower

dropping below 9,000m disengage GM-1 (throttle setting irrelevant)

dropping below 6,000m re-engage MW50 with throttle at 49% or lower

i think you need to disengage at low revs as well but never tested it to see

running out of MW50 and leaving it engaged is apparently a bad thing

some people also say never run an MW50 equipped plane above 100% AT ALL unless the MW50 is engaged ... but to be honest I have never encountered a problem in game

interesting....

http://en.wikipedia.org/wiki/Focke-Wulf_Ta_152

Fuel capacity was 595 L (157 US gal) for the H-0 model, with the option of a 300 L (80 US gal) drop tank on the centerline.[citation needed] The H-1 model carried an additional 454 L (120 US gal) of fuel in six unprotected bag tanks in the wings; typically, one of these tanks was used to hold the MW 50 methanol-water mixture and another for GM-1 nitrous oxide.


do we have an H0 or H1 in game? anyone know?

wonder if API could do the job in game then? :P

Why are you laughing, This info is spot on since the TA-152 has MW-50 and GM1!

perhaps DKoor was imagining that our TA met a 47 at 10k http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

The MW-50 boost can only be used for 35 minutes. After the fluid is run out, you must turn off the boost. Otherwise you will damage your engine.

So you engage it below 50% throttle and then you can throttle up to 110% after engaging it? And throttle down to 50% before disengaging and then throttle back up after disengaging? I always assumed that boost was used when 110% wasn't enough. And I don't leave it on for minutes at a time, and yet the engine still ends up falling apart. Great plane otherwise though, takes most planes out with just one burst.

And landings are pretty tricky, might I add... Just finished a mission in a campaign (in which I limped home with yet another damaged engine due to boost) and almost ran out of runway &gt;:/

You have to be at High Alttitudes for teh GM1 not to ruin your engine... http://forums.ubi.com/images/smilies/25.gif

bump for procedure for engaging/disengaging boost

To engage MW50, I pull the power back to 0%, engage MW50, push back to 110%

To disengage, same procedure.

MW50 is not a power boost, it's a mixture of methanol and water. When added to the fuel air charge, this mixture reduces detonation and peak combustion temperatures. This allows the engine to run for longer periods at power settings that would otherwise destroy it in very short order.

The method used by the Germans to add the MW50 to the fuel/air charge was such that if you throttled up to dangerous power levels before you started the MW50 you would damage the engine very quickly (I'm sketchy on the details but it was so).

To safely engage MW50, you should have throttle set below 50%. This does not start the injection immediately, it turns on the automatic system that starts injection of MW50 whenever the engine is running at dangerous power levels. You can safely turn on MW50 as soon as youtake off provided the throttle is below 50% when you do so. None of the MW50 mix will be used up until the throttle setting exceeds 100% and the automatic system cuts in.

Other constraints on the system are mention in Daiichidoku's post above (http://forums.ubi.com/eve/forums/a/tpc/f/23110283/m/1321024197?r=4031024197#4031024197)

Interesting... But I can seem to run the engine at 110% for like 10 minutes at a time without the MW-50 (with full radiator flaps open, of course) before it starts to overheat. And then the plane goes like it's on steroids when I engage it (before it falls apart, that is). Is it modeled differently in the sim than in real life?

Frankthetank36

BTW, how are you supposed to use cowl/radiator flaps in this sim? I usually fly with them fully open so that I can get more power (unless I want to slow down), do they produce any noticeable drag?

Easiest way:

When you get in the airplane, arm MW50 - you'll only have to firewall the throttle and get all the power at once without having to fiddle with the engagement-procedures.

When switching to GM-1, make sure you are well below 100% while shifting.

MW-50 will only be consumed when you're flying at more than 100% when engaged.

The methanol can provide some power boost, but the primary purpose is to reduce or delay engine damage while running at perilously high boost pressures by reducing combustion temperatures and detonation.
