FW 190 D-9 Top Speed
 

Hi Guys
looking for some info on the top speed of this plane, most books are showing it with a top speed of 426 MPH, but have seen some reports saying it could hit 440

would that be a sub model of the basic plane ?

also seeing some of the British Test reports, that were done on it, and most of them were haveing trouble hitting 400 with the planes they had (but I think most of these may have to be taken with a grain of salt, as I believe they say one blew a engine and the other engine also ended up with some troubles)

The official performance statistics from Focke Wulf are as follows:

Fw 190D-9: 426 mph @ 21,654 ft. with the Jumo 213A-1 engine (1770 hp)
Fw 190D-12: 454 mph @30,020 ft. with Jumo 213E-1 engine (1870 hp)
Fw 190D-14: 441 mph @ 24,278 ft. with the DB 603E engine (1800 hp)

I don't have any statistics on the D-9 with the Jumo 213A-2 with MW (2240 hp) but it would be considerable faster than the A-1 engine.

Fw 190D-9 service ceiling
 

On a related topic, I have read several sources that cite the Fw 190D-9's service ceiling as 32000 ft. Is this true? I thought the Fw 190D-9 had significantly better high-altitude performance than its 190A predecessor.

Flight test date for Fw 190D-9 Wk.-Nr. 210 002 with both "Erhöhte Not-/Startleistung" and with MW-50 injection can be found at NASM.

Some time back a poster, 'Naudet' on the AAWII forums posted the following:

Re: FW 190 D-9 Service Ceiling
 

Focke Wulf lists the service ceiling of the D-9 as 36,417 ft.

Thank you Sirs

for the Alt, yes I have also seen it showing it as being pretty low, and others, more of what you would expect

the one thing that got me though was they were also saying the top speed at pretty good at the top Alt level, so think the just screwed up

Hello peoples!
In D.Herman's great work "Long Noise Dora" German specification indicate 704 kph=437,5 mph using MW-50 system.
Many useful inform you can find in A. Williams' site as follows:

Gentlemen:
On 20 Jan 1945, my flight of four bounced estimated 40 FW-190s. I eventually was alone with quite a few of them and finally decided to head for home. Several FW-190 D-9 (est 12- 15) chased me at an estimated 32,000 feet all the way from Regensburg to Alps but kept falling further and further behind. My P-51D was rated at 437 mph top speed so I doubt these FW-190s could do over 430 mph.
Cordially, Art Fiedler

p-51 cadillac of the skies!

For Sondernotleistung (MW50) of D-9 Jumo 213A I find 702km/h = 436mph @ 5,5km alt.
For Sondernotleistung (MW50) of Ta152H-0 Jumo 213E I find 742km/h = 461mph @9,5km alt.

The Ta152H was a Höhenjäger (for high altitude), so it was NOT designed for low altitudes (ground level).

well to the luftwaffe aces and such it was well" the best plane by kurt tank.built. yet why didnt the aces use it more like Rall. BAR /ETC.JG 52 sqn J Weies was persmistical.when he was to fly it in action.didnt he get killed by spits. flying it.
to me my name sake it was a fine plane nice lines and such i liked the ta 152 the best.

Because that is how every supercharged piston-engined fighter works: they are all fastest at the full throttle height of their engine. The engine produces maximum power as long as the maximum boost can be maintained: as height increases drag decreases (lower pressure) and the aircraft goes faster, until the supercharger can no longer maintain the maximum boost, power drops, and the aircraft goes slower. With a two-speed supercharger you can start the process over again, and gain speed for a while, thus presenting the familiar "saw tooth" speed profile with two different full-throttle heights.

Apologies for oversimplifying.

Restricted to a single-speed supercharger, there's no reason to expect the Dora to go significantly higher than the Anton. Hence the addition of funny additives.

Dora9, are you referring to Hptm. Robert "Bazi" Weiss?
AFAIK, he was killed in a big furball with a superior number of Spitfires, but that does not say anything about bad qualities of the Dora9.

Also, LW Aces were not simply allowed to choose their fav plane, they had to fly with what their units were equipped!
probably a better example of a LW top ace who was not successful in the Dora9 is Gerd Barkhorn, who did not score a single kill while flying the D9.

Heinz Bär on the other hand may have shot down two Tiffies/Tempests during Bodenplatte, but it is not entirely sure that he used a Dora9 during the assault.

HI. thanks yes my german his not that good. yes spits got him.
___________
its just as i play il2 game i cant control it at all.>IT WONT TURN"" i have no rudder just joystick. i wondered if thats how it flew. but i might be wrong.as it was developed by some ex aces the games planes.
_________________
as for the aces yes i read in books that it had a slower roll rate than other fw 190s. but was faster and a match for the mustangs.
thanks again for info.
