What use did these 2 pieces have?

[João Yazalde]

I have seen these 2 parts of the plane. The one on the wings is new to me, I had never seen a piece like that, on the other hand, the one behind the propeller I have seen on other planes, but I don't know what it was for, what use did they have?

 

[GrauGeist]

The device on the wing's leading edge, is called a "slat" and it changes the wing's performance when the airspeed drops.

The object ahead of the exhaust, in your image, is an error. That should be the first of six exhaust stacks, which were not painted.

 

[João Yazalde]

Thanks. If it's not too much to ask, why did it have these red lines?

Wing walk lines, bad to walk out of the lines

Exactly.

If you look at the rear of the wing, against the fuselage, the area just oitside of the red line is part of the flaps.
A person's weight on that will cause critical damage.

Is he asking about 1) cooling air tunnels or 2) radiator?

It appears the area they marked was the early "cooling tunnel" at the exhaust stacks.
It was hard to see on my cellphone, but only the early 109s had that feature.

I see it only on the "E" up to at least the -7. The "F" seems to have lost it

Also Ju-87 family had the similar "cooling tunnel" at the exhaust stacks. These can be noticed on all sub-types.

Actually the early Bf 109A...D had them too. But in the case the cooling slots were flat, slanted apertures both for the air intakes and outlets.

However it looks like the E exchaust system was retro fitted to the ealry 109 as well.

A technical question for Calum Douglas and others. What is the effect of the cold ram air (especially at altitude) on only the lead exhaust pipe and the last being the hottest?

 

[João Yazalde]

replying to fubar57, I am asking about part 2 of that BF 109 E4. Like I said, I've seen it before, like on this plane.

 

[João Yazalde]

so it works like a hot rod, the engine needs that part to not overheat

J João Yazalde Part 2 is the Bf109's oil cooler. The engine coolant radiators are under the wings. On the P-40 example you have shown, both the coolant and ol radiators are housed in the one large duct under the engine.

In your first shot, the leading edge slats on the 109 normally would not be open in level flight. The are meant to deploy when the wing approaches a stall like at very low speed or in tight turns. They were automatic and the pilot had no control over their function.

Oh, you mean these?:

 

[Crimea_River]

Yes, those are the coolant radiators.

109E flap question

Does anyone have some pics or drawings that show the area where the wing radiators meet the flaps on the 109E? I can't seem to find what I'm looking for. TIA Tim

One more thing, I have also seen this piece in the bf 109, what is it for?

 

[fubar57]

Super charger intake

 

[Wurger]

With the above.
