Simple: What color were the superchargers? Brown, rusty brown? Any pics?
-
Looks to be a gunmetal black with dusty brown exhaust staining

Looks like typical exhaust system rust color with a nice coating of tasty lead oxide.
-
The superchargers get extremely hot when in use and this causes the metal to turn a variety of colors.

God those are sexy

akak and guppy.......great...and as spork said....sexy pictures. but i'm confused. a bloo p-38?

I assume that is supposed to be the all Black 38 for night op's but I could be wrong
link I found for black 38 skin

Thanks for the help. Couldnt find those pics anywhere.

Recce P38. Better known as the F5. We've got up to 4 of em flying in DGS. No guns, just cameras to get the strike photos
Here's Del's bird. All three frames he's gotten the strike photos so far and made it home. Hasn't fired a shot :)

Ahh give him a proper picture. ;)

That is awesome. Wish we had a good reason for them in the MA.

i can think of some darn good reasons for them in fso, although finding someone to volunteer to fly an unarmed bird may be hard.......

For US PR birds, look at the Mosquito Mk XVI. In US service it was the F-8 and we do have some skins for it as such.

They have an F8 mossie at WPAFM in Dayton. Pretty airplane it is.

I wondered what that skin was for on the mossie bomber :)

It wasn't blue. It was black. It's been shown the "blue" photo is really a badly developed and OLD photo of a black plane.
Similar to the "blue" P-51Ds that really were OD, not blue.

Not in this case....
It was painted blue....

Reminds me of all the photos that spawned such inaccuracies as this:

There are numerous WWII Kodachrome photo that, because of improper storage of the negatives, the dyes degraded turning OD green into a bluish hue. Some P-51 owners either didn't know, or elected to ignore this and go for blue anyway. Most F-4 and F-5 photo aircraft were painted various shades of blue.

what is the gizmo on the top of the turbine?...on some planes it has tubes running forward into the nacel and in the one photo it appears someone cut the tubes off.
-
A lot of the small intakes, louvers and gaps you see along a P38's boom are for air to cool the interior of the booms. They have got a lot of very hot fluids (exhaust, coolant, compressed intake air, oil) flowing through the tubes and ducts in a very confined space. Even the spark plugs had their own cooling blast tubes.
The strange looking intake that crosses over the top and shrouds the center of the turbocharger is to help cool the turbines bearings and oil.

I like it. I know it is inaccurate for war time, but I once did a P38 model that I painted blue with red nose and spinners.

Ok, a similar question.
I have a friend who used to play around with car engines before he decided to go into a different line of work. I told him that the P-38 had turbo superchargers. He couldn't see how that would work. You can have a turbo charger, or a super charger, not both.
So how did this work on the P-38? I never did get around to researching the answer. :headscratch:

Turbochargers were originally known as a turbosuperchargers when all forced induction devices were classified as superchargers, nowadays the term "supercharger" is usually applied to only mechanically-driven forced induction devices.[3] The key difference between a turbocharger and a conventional supercharger is that the latter is mechanically driven from the engine often from a belt connected to the crankshaft, whereas a turbocharger is driven by the engine's exhaust gas turbine. Compared to a mechanically-driven supercharger, turbochargers tend to be more efficient but less responsive. Twincharger refers to an engine which has both a supercharger and a turbocharger.

Cap is right, however there have been a few cars which employed both turbocharging and supercharging on the same engine, most notably the Lancia Delta S4 Group B rally car.

The P-38 had both crankshaft driven superchargers, which were standard equipment on the V-1710 Allison V-12 engines, and turbochargers. The two stage single speed centrifugal supercharger driven by the crankshaft was an integral part of the engine. The General Electric B series turbocharger was added by Lockheed to compensate for the Allison supercharger being a single speed unit, and as such, unable to compensate for decreased air density at high altitude.
It was possible to equip the Allison with a two speed two stage supercharger, it just wasn't done. Just another mistake by a barely functional War Production Board. Had the Allison been so equipped, it would have been a perfectly competent high altitude engine without a turbocharger, although, like the Merlin, above a specific critical altitude, power would have dropped dramatically. Where the critical altitude occurs depends upon the gear ratio in the supercharger drive. That is why/how specific Merlin engines were tuned for particular altitude ranges. The turbocharger allows an engine to hold the same power to any altitude, so long as the turbocharger has sufficient size to supply the required air without exceeding its own RPM limit. For the General Electric turbochargers used on the P-38 and P-47, the critical RPM limit was reached at around 33,000 feet.
On the P-38, the turbochargers fed the superchargers, which is standard operating procedure for engines that use both a supercharger and a turbocharger. This was even done on heavy truck diesel engines, the Detroit Diesel 8V92 TTA engine was equipped with a crank driven supercharger (found on almost all of the old Detroit Diesel two stroke diesel engines) which is in fact the basis for the "blowers" (6-71, 8-71, 10-71, and 12-71, the "14-71" is a purely racing unit) you see on hotrod engines. The numbers in "8V92" designate the engine size, a V8 with 92 cubic inches per cylinder, which had an appropriately sized crank driven supercharger, also designated 8V92. The TTA suffix denoted twin tubochargers, and an aftercooler, also known as an intercooler. So you had a 736 cubic inch diesel engine with two turbochargers, feeding a supercharger through an intercooler. The same configuration has been used in racing. It is rather complex, but if the correct balance is achieved, massive amounts of power can be made.
-
Those planes also spawned the term "intercooler" to differentiate charge coolers between multiple stages of supercharging and the "aftercooler" which cools the charge after the last stage of supercharging.
Sadly, someone messed up the terminology long ago and we are stuck with "intercooler" to describe all charge coolers.

Thanks to all who helped. This is the result.

You gonna post the picture of the final product? You'll get bonus points for using a 479th paint scheme, don't want to sully the beautiful P-38 by dressing it up like a Fiji head hunter like those 80th P-38s.
ack-ack

It is getting a 392nd FS, 367th FG "Little Buckaroo" paint job. Flown by Major Robert "Buck" Rogers (CO of 392nd FS).

Blasphemy! The green trimmed birds rule! :D

I WOULD LOVE to fly an F5 in FSO!!!!! and i dont care what any of you say P38s are the SEXIEST warbirds spittys #2.

Bah, F-8s are much better. Prettier too.
