I stand corrected for the error on the F4F.

But.

I noticed no one denied that ole Tank tried to copy the P-51!!!

LOL Westy, I doubt that - the Fw 190C was designed before the Mustang had even begun operations.  Also the shape and size of the belly pod is a lot different if you see it from another angle, the internal configuration is different, and the purpose is different as well.

On the Mustang, the belly pod houses the radiator and oil cooler.

On the Fw 190C the radiator is an annular type which is integral with the engine cowling.  The oil cooler is contained in a scoop under the nose.

The Fw 190C belly pod contains the turbosupercharger as well as an intercooler.  The engine exhaust is directed to a large pipe on each side of the plane.  The pipes (one on each side) go over the wing root and down into the belly pod.  

The aft portion of the pod contains the turbo, and there is a vent at the back of the pod for the wastegate.  

The front half of the pod contains the air intake ducts and an air-air intercooler.  Cold air enters through ducts on either side of the front opening and is directed to the turbocharger where it is compressed.  The compressed air is then passed through the intercooler and forward (see the pipe under the plane) to the mechanical supercharger attached to the engine.

The intercooler takes cold air from the center of the forward pod inlet and there is a flap in the bottom of the pod for hot air exhaust.

It's interesting to compare this to the system used on the P-47.  Both systems are identical in function and nearly identical in layout.  However instead of having all this equipment hanging out in the breeze and creating drag, Seversky built the plane around it, which was a much better solution.  Tank had designs of this type as well, but due to the failure of the prototype, they were never constructed.

Turbo Compound engines used 3 exhaust driven turbines and a hydraulic gearbox to add extra horsepower to the crankshaft. meaning that they extracted the least bit of energy form the axhaust gas...

These engines had the best Specific fuel consumption of all aircraft engines ever built (they were hidiously complicated tho)

 Thanks for the great info! I'd never seen the "C" before and no I was not serious about an similarities with the P-51 at all.
 I've got to rebuild my book collection again

Cavity search for Ripsnort!

They're already waiting for Pongo.

Westy, the most interesting books I have on Fw development are:

"Kurt Tank: Focke-Wulf's Designer and Test Pilot" by Wolfgang Wagner
Most interesting of the three, includes interviews with Tank.  Some problems with the translation though - errors in some tables and some of the technical terms are misused.  Has more flight test data than the others.

"Focke-Wulf Fw 190 & Ta 152: Aircraft & Legend" by Heinz Nowarra
Probably the most technically detailed of the three.  But again there are some flaws in the translation.  There are some definite contradictions between this one and Wagner's book.  Nowarra has an earlier book "The Focke-Wulf 190, A Famous German Fighter" that is less technically oriented but not as good IMHO.

"Focke-Wulf Fw 190: Workhorse of the Luftwaffe" by Jay P. Spenser
Most scholarly of the three, has a great bibliography.  Deals with the restoration of the Smithsonian's F-8 but has a LOT of info on captured 190's and use of 190's in Schlacht units.

Only Wagner's book is still in print in the US, but you can find the others from www.abebooks.com
