Ta152, some facts.
« on: May 29, 2002, 05:06:10 PM »
THANKS TO STAGA FOR PUTTING THE PICTURES ON HIS WEBSPACE!

I owe you one mate! (atleast one) :)

Ok, here are some facts, a chart and another nice speed comparison data between all different Ta152 types.

The first chart, speed diagram are from 1943, 2 years earlier then the Ta152 H-1 which entered service in January 1945.

The chart displays 3 curves, all Ta152's.

Remember, one, it's from 1943, 2, the Ta152's in here are TA152 A modells, the H modells had slightly better high performance.

The second diagram explains it self.



Second one bellow. Be sure to check the GM 1 boost speeds especially since it's those, that I THINK are what's been either not modelled, or slightly undermodelled in AH. GM 1 was used at altitudes above the maximum boost altitude. Mw 50 could only be used up to where the Maximum boost ended but not above.

What differed the H-0 from the H-1 was a few things, first, the H-1 used Jumo 213E-1 engine, the H-1 thus had both MW50 and GM boosts. The H-1 also had wing tanks, giving it a greater range then the P51D on internal.
Thus the H-1 had higher wingloading and turned a bit worse, but was better at high alt aswell as low alt, greater range aswell.

Something else that I think might be wrong is the fact that the H-0 modell had climb rate of 20 meters/s at sea level, although the H-1 was heavier the boost would bring this up to about the same but I need to do some more research about it.

One more thing, the H-1 used a field kit which was suplied by Junkers to units with Ta152's. It increased the horse power of the engine with 150.



All!

Ps. I just saw the exact date on the speed diagram is 4.9.43.

4:th of Septemper 43 so it's really just about 1 year and 4 months before the Ta152 went into service.

Staga, can you make one of this too so we can see the high alt performance, between 30 and 50? :)

I did that in a hurry; better check if alt/speed conversions feet/km and mph/kmh are matching.

btw were those FWs having 4xMG151+3xMK108 armament or what does it read in upper right corner of the pic? Looks kind of heavy load?

Yup Staga, these planes have heavier armament, 3x30mm and 4x20mm, Ta152 A's with short wings. Ta152 H-1 still weights (with all boosts systems and wing tanks full etc) a bit more, now... do we have all boost systems?

I've got some more pictures if you wanna see how the armament is mounted.

What is interesting to see with the chart, is that every new speed increase (first you got a line 90 dgeree up then speed increase) is at lower alt in AH then on the Diagram.

I'm still leaning towards the fact that the Gm1 is undermodelled not modelled at all. Do you know how to read teh diagram at teh top? A bit messed up there.

Pyro, can you look at this and answer some questions I have?

Btw Staga, not sure if GM1 and Mw50 (low/medium alt boost) is modelled at all in AH, if it is, it will explain that the AH Ta152 is faster bellow 30k then on the chart. The Ta152 A didn't use MW 50, only GM1, the GM1 container was kept a bit behind the pilot seat.

What about acceleration?  The 152 does that it seems worse then a c-47 above 300 mph.

Kurt Tank described teh acceleration of teh TA152 as "very rapidly", can't find any numbers but as it is now it hardly accelerates at all in level flight, specially not above 300.

Just a prediction: Data from a prototype a year and a half before the plane entered service will get you nothing from HTC.

Overdoing yourself, are you ?
