Empty GM1 tank in Ta 152H

According to this thread:

the full 85L GM1 tank in a Ta152 adds about 104kg or 228lbs of weight to the aircraft.

Assuming GM1 is not modeled in the game (otherwise the 152 would be faster above the rated altitude of its engine of ~32000ft) could the ta152 be modeled with the GM1 tank empty? In addition to saving 228lbs of weight, this would also improve the handling of the plane since the GM1 tank is located behind the cockpit, which is aft of the center of gravity.

There's so much wrong with the 152. That would be a step in taking out the inherrent instabilites, though!

It is faster above the maximum rated altitude of the engine. It doesn't live up to the 472mph stated in books etc. If I remember correct max speed in AH is at a bit lower altitude and the speed is somewhat slower.

Not saying I agree with the Ta152 modelling in AH, jsut saying that it is modelled with GM1.

I wish they would remodel this plane, as well as the mossie. Both planes are soooooo AHI standard and are really "buggy" with AHII FM.

I would put remodeling all current planes to AHII standard far above NEW planes.

the remodeling process could also produce more variants, for instance remodeled Mossie could have the one we have now, and the fast bomber from later war.

262 could be remodeld and the 2 cannon "bomber" version added.

when they did the B17 they could have made an "F" etc.

From what I understand, GM-1 could only be employed above the rated altitude of the engine, so in the case of the Ta-152 32k.

Our Ta-152 produces it's full boost until that altitude at which point manifold pressure steadily decreases as you climb higher. Max speed of around 465mph is also reached around 32k.

I think that the use of nitrous oxide would allow for full boost (or higher than what we have) to be run at altitudes where the manifold pressure would normally be dropping due to the thinner air. However, my understanding of how GM-1 worked is fairly basic, but I think if it was being modeled it would have a noticeable effect on performance at high altitudes. What I do understand is that MW-50 was used below rated altitude and GM-1 above rated altitude. MW-50 could be used above the engine's rated altitude, but the power gains were only slight due to charge cooling effect.

While a complete overhaul of the Ta-152 flight model might be a long way off, simply removing ~230lbs of deadweight from the back of the aircraft could help its handling and stability and reduce its tendency to flat spin.

What dead weight?  GM1 is modeled.

[Wilbus]

Yes the GM1 was only used above the maximum boost altitude of the engine.

Had the GM1 not been modelled there would've been no difference between wep and no wep above maximum boost altitude. The max boost altitude of the Jumo 213 E engine was around 35k ft.

Max speed is not archieved in AH at 32k, it's higher then that but lower then 41k, can't remember exactly what alt.

The GM1 is modelled, to what accuracy is a different question.

If I remember correct Pyro has stated before that both the Gm1 and MW 50 are modelled with it.

tendency to flat spin? Never noticed that.

Much of the instability noticed is due to long wings I believe, thus requiring much more rudder input in order to roll clean.

Ah, for some reason I thought that GM-1 worked by allowing normal boost levels to be maintained. Interestingly, the 109g-14, k-4, and 190d-9 all have different boost levels for WEP and non-WEP above full throttle height.

I think you're right that GM-1 is modeled in some form since top speed doesn't really drop off that quickly once above maximum boost altitude.

Found this chart on another website:

It's hard to make out but there looks to be a curve that says "mit GM-1" in the upper right corner which could be the Ta-152H with GM-1 speed curve. This could be where the often quoted 472mph top speed comes from.

While searching for Ta-152 flight data I stumbled upon this thread on another website:

amid the typical bb arguments there is some good performance data, especially on pages 3, 4, and 5.

As for flat spins, I've done it twice (never intentionally!) while over airfield and attempting to scrub off airspeed to land (managed to recover once and I think other time was in TA). Another time I got a kill while climbing vertically, then got stuck in nose up attitude and slid down a few thousand feet tail-first into the ground.

Too bad there can't be some option to not fill the GM-1 tank since it's completely useless except for very high altitude flight.

until CT is finally here then it will be needed
