It could be something as simple as one being for air, the other being for water. Also, in the mid 1800's, thats well before the digital age ;) It may be a simple error in the patent office, or one hand not talking with the other. This has happened before, and the 1st patent always wins.

Looking at the photo's, the model they tested with is all wood. The V3's center section was steel tube with aluminum skin, with wings wood. Also, I cant see if they put any turbine blades into the engine intakes. These two discrepancy's would greatly increase its radar signature.

I had a feeling it would be easy for you guys. I was hoping to throw you off with the early model radial version.

OK. This looks like fun. I dont know of many oddball aircraft, but this one. I had a little fun in Photoshop to give you guys a run for your money.

The Cat, hands down, the most important flying boat/amphibian of the war. Used in every theatre, in every possible way, and a part of some of the biggest and most crutial battle's of the war. Flown by not only the US, but also England and Russia. Russia made an unknown number of Catalina's...

Not much. The F4U and P-38 both started prototype flights at about the same time. The main delay was that the US simply didnt want to invest a lot of money since they were hoping to avoid war. Once war started, things took a quantum leap in terms of financing aircraft development. With that...

The Allison V-3420 had no such problems. It was never used in any production aircraft, but many many prototype aircraft. A varient of the B-29, the B-39, was tried with the V-3420's in case the R-3350's didnt work out. And the XB-19, served for 6 years on V-3420's as a cargo aircraft.

Also the ram air intakes would be taking in cold air. The air intakes for the supercharger on the BMW are behind the engine, so it is constantly ingesting hot air from the cylinder heads. Using cold air is a LOT more officiant in terms of engine performance, but as stated, but big intakes will...

It all depends on how you route the oil. If your dumping the cooled oil into the back row first, then it gets more cooling then the front row. I dont know how the oil is routed though.

Very good point. The 801 powered Ju-88 used the same power egg! So it all had to fit within the cowling to make it adaptable to other designs, since a chin mounted cooler could interfere with something on other designs. Im guessing the size of the cooler had to do more with cooling that back...

One alternate location would of been under the engine in the chin. Like many of the Japanese aircraft including the J2M series. The J2M had an extreamly streamlined coweling, large spinner, and the ducted fan, but opted for a more standard approach to oil cooling.

Overall, I like the FW-190A series as a fighter, but one "feature" has me EXTREMELY puzzled. The oil cooler. Now, im sure all of you know, most radial (or air cooled) aircraft engines had a separate oil cooler. Typically placed in the chin (A6M, P-47, LA-5) or in the wings (F4U, Sea...

I think it was "claimed 2/3's". In a pack of 100 B-17's, if a 109 goes down in the middle, about 200 trigger happy gunners are going to claim it.
