f4u field mod we should get -turbo!!!-

[-towd_]

howdy jsut stirin up touble but i was wondering if you ever considered that they did field mods like this..( turbos wired to "on" position way below rated alt) seems like they were gettin alot of proformance out of this mod this was a practice where they burned up engines with alot of extra power cause they had to should it be modeled?

-----The Wildcats' turbochargers, not to be engaged below 10,000 feet but wired open anyway, wore out the engines in 25 to 50 flying hours.-----


is there any way we could have tat option baby? f4f from hell!!!

i got it here

Howbout 190 with turbo ? I'm sure you would love it

From a couple of accounts I have read  it actually went the other way too. Units would "de-rate" or "de-tune" the engines to get more life out of them.

Staga, Never seen a pic of a 190 with a scoop like that. What is it, and what were they testing on it? Some kind of turbo-supercharger?

Towd, someone is blowing smoke up your ass.  No turbos on F4U.  F6F had one prototype with a turbo R 2600.  There was one F4F turbo prototype as well.

Verm that's one of the Fw 190C prototypes with a Hirth turbosupercharger in the belly.  They later morphed into the Ta 152C but without the turbo.  They never go the turbo to work due to metallurgy problems - their high-temperature alloys didn't cut it.

Verm that is the prototype of the Fw190C, with a turbocharged BMW801 engine.

Yes, that scoop is from the turbosupercharger. Tank stopped the develop of the model due to metallurgical low quality, and changed to DB603 and Ju213 engines, leading to the development of the D series and Ta152.

ROFL I see funked said it before...

me and my fixation on answering the posts too soon

Verm, that was the FW-51D  

In the Battle of Midway thew F4F's had thier turbos wired on. The increase in performance was in life-death situations against the Japanese aircraft was warranted in the eyes of many. Easier to replace an engine than a pilot.

Westy more likely they are talking about the superchargers not actual turbochargers, theres is a huge difference.

If you want a manly Pratt R2800 with a turbosupercharger you need only look to the P47D, 2600hp and it held that power for a long ways.   The other supercharged pratts could be set at 60 mp or 65 mp for 2250 or 2300 hp.  Perhaps that is what you were talking about?

Yep Indian, no turbo on F4F.  Sounds like they probably had the planes running on high blower full time, which might give some added low altitude performance at the expense of engine life.

Funked,

I think he meant the F4U-3 or -3B or maybe even the F2G? Everyone knows abou the the F2G because of the racing history but the F4U-3 is not as well known. It had a similar engine to that of the P-47 with a turbo supercharger  in the belly with a large scoop. This delivered 2800HP up past 40,000Ft. This aircraft could reach 480MPH at 40K with
"plenty of climb left in her" according to test pilot Bill Horan. Vought built at least two of these A/C and delivered them to the Navy . However Goodyear built 26 of them and delievered them to the Navy in June 1945. They were in Naval inventory until 1949 being used for high altitude testing. Since there were almost as many F4U-3 built as Ta-152 why don't we model it too? Yeah that's a great idea. That will give the Ta-152 something to do while your all by yourself at 45K.

Ahh you are right, the XF4U-3 and XF4U-3B had turbo engines.  But this was a pair of prototypes, not a production version that saw combat.  Comparison with the Ta 152H is ridiculous.

P-47M and N were production planes that saw combat, and will give the Ta 152H plenty to worry about.

Another off-topic...  Sorry  

Kinda funny Oldsmobile.... Say charged and MW-50

Correct if I'm wrong:

Turbo charger: exhaust driven charger where turbine assembled in exhaust pipe gives power to other turbine assembled in intake manifold (like Saab   ).

Super charger: In WW2 usually gear or axle driven centrifugal charger. Charger takes its power from crankshaft.  

Then there were something called "turbo compound (?)" which was used at least in Lockheed Constellation after ww2.
If I remember right it has 3 turbines in each engines exhaust pipes which power was added to give more power straight to crankshaft. These ones were quite fragile ?

turbosupercharger is the full word for an exhaust-driven supercharger (aka turbo).
