Ta152 charts, tests and comparison tests

[Wilbus]

All pictures messed up, posting link instead.

Ok, some more info about it, some tests that were made during the war in germany.

First out a speedchart with the Ta152 using 3 different engines.

The one using the Jumo 213 E is the one interesting for us. It's a Ta152 H-0, lacks the MW50 and (not sure about this on this particulair airplane) the GM1. Somebody better at german might wanna translate that.

Second out is a chart with some of the different Ta152's.

Last out, and maybe the most interesting as it shows the same thing as the other two charts but adds the climb speed at the deck.

The Ta152 being used is a Ta152 H-0, it doesn't have MW50 nor GM1 injection making it a bit lighter then the H-1 but takes away a couple of hundred horse powers.

This chart is a comparion between the Spitfire Mk XIV, P51 D and Ta152 H-0.

As you can see both the P51 and Spitfire XIV are pretty much spot on, both acording to other data available and AH.

Spitfire Mk XIV speed at the deck as shown on this German test, is 574 km/h, that is 358 Mph. That is right on the chart on HTC's webpage.
The P51 D is shown as 600 Km/h at the deck, that makes 375 mph, AH's does 370 mph. (Unpork the P51 D! )
Still, that's pretty close.
P51 D shows as 18 m/s climb rate at the deck, our P51 D does 17.17 m/s. This could be that the P51 D in the test is a non bubble canopy P51 (one of the earlier D modells).

Spitfire in AH climbs better then the 23 m/s, AH does about 24,7 m/s.

Karnak, can you confirm this? I am having trouble finding the climb speed for our Spit XIV in the Spitfire bible.

Ok, enough of the ranting, you can see for your selves.

Conclusion
The Ta152 modelled in AH, is infact the Ta152 H-0, lacking the so important MW50 and GM1 injections that the H-1 had.
However, it has been modelled with the Weight of the H-1, inlcuding the wing fuel tanks which is atleast one of the reason that it climbs like a rock and accelerates really bad. Think about it, add 1000 lbs to a plane without giving it some kind of extra power boosting of bigger engine, both the climb rate and acceleration will suffer.

All speeds of the charts I've shown have about the same speed as the one in AH, all the charts I've shown show the H-0, some the H-1 aswell.

Let's hope you can find all the pictures there, should be three, don't know how reliable that homepage provider is.

[Wilbus]

Nope, images refuse to be posted here for me. Will have to watch them normal, paste the URL in the browser.

[Naudet]

Wilbuz, interesting info, but i think your are wrong with two things.

The original speedchart is for a TA152C or E, cause it hast only a wing area of 19,5mē but the TA152H had 23,3mē.

The DB powered is the TA152C and the JUMO powered is the TA152E.

So those speeds are NOT for a TA152H.


And the comparison table is not a german test, it looks like a table published in a book, that compares the acutal plane data know to the author from official sources. Thats also the reason why the speed of the Spit XIV matches exatly HTC charts, cause i am sure they both relate to the same source.

Speed difference between the C and the H weren't very great, depended on engine only almost.

[-ammo-]

what were the differences in the numbers between the C and the H? Did they use different engines?

Bible of Spit performance

[Wilbus]

H used Jumo 213 E and Jumo 213 E-1 (H-0 used E-0 and H-1 used E-1).

C used DB603 LA engines. Giving them a max speed of 385mph at the deck.

The C was the destroyer version, ment to replace all twin engined destroyers. The plane had armament which consisted of all the way from 2xMg151's to 4xMg151's and 2x30mm.

It also had a shorter wing as Naudet said, basicly the same 190 wing but slightly lenghtened.
Only 2 C's ever saw action.

Thanks funked

Punt for Wil!!!

Funked posted the same link I would have.

Spit14 climbs on the numbers.

I found a picture of a ta 152 helmet original design
Right now the helmet is way undermodelled.
Actualy it sux way IMHO !!



Pyro Superfly hiTech fix it now

yep, right on the numbers for a 2000-2200PS Spitfire at ground, but keeping this performance up to 10-12k where the "Boscomb Spit" would already lose power at 2k....  yeah, right on the numbers...

Looks pretty close to me.  Maybe you can point out errors.

Max. rate of climb in MS supercharger gear 5,110 ft/min. at 1,700 ft.  
Max. rate of climb in FS supercharger gear 3,600 ft/min. at 21,800 ft.  

Time to 10,000 ft. 2.3 mins.  
Time to 20,000 ft. 5.1 mins.  
Time to 30,000 ft. 8.35 mins.  
Time to 40,000 ft. 15.05 mins.  

Rate of climb is 1,000 ft/min. at 38,900 ft.

Looks like the Spitfire Mk XIV in AH climbs at about 5,100fpm at 2,000ft and about 3,600fpm at 22,000.

In MS supercharger gear 391 mph at 5,050 ft.  
In FS supercharger gear 446 mph at 25,400 ft

It doesn't look like it hits 391mph at 5,000ft though.

Overall the performance of the AH Spitfire Mk XIV matches this very well.

[Wilbus]

Yes it does Karnak and it matches the test report I posted very well aswell except for climb speed being a bit lower, which makes me wounder even more why both the spit 14 and P51 D are pretty close, while the Ta152 is way off in many ways.

It's a Ta152 H-0 for sure, with about 1000-1200 pounds too much weight. Add the MW50 and GM1 (they gave around 300-450 HP more) or remove the weight and the wing tanks.
