BF 109E-4 Air filter ( Fieseler type)

[Tolga ULGUR]

Hello everybody

I am planning to built a BF-109E-4 with the markings of S9 GT from /SGK 210.

As you can see in the picture this machine has a different air filter. Due to my reference this is Fiesler type filter.

Does anybody here has reference, information or drawing about this type of filter.

If it s not known I will continue by using normal/std filter.

Thanks

Tolga,

 

I know these airfilters but don´t know anything about them.

Maybe an improved airfilter at Fieseler plant, a better/increased airflow, some kind of provisional sand filter or mounted on machines fitted with the "N" motor or the GM-1 device?

Unfortunately I can´t answer, but I found two photos with slightly different explanations.

And have a look here:

I´m sure, there are a few photos of this intake - you just have to take a little time and a cup of coffee....

C'est super Alain.

Really much appreciated. And nice work on your rendition

Merci beaucoup

Same exact scheme that I've chosen for my Dragon kit, and the same problem; I don't know of a kit or AM that covers this particular filter.

[LSP_K2]

Where did you get that filter, Alain? Another question, are there any really noticeable differences between the E-3 and E-4, aside from the obvious canopy differences?

[alain11]

the front part of this filter shouldn't be too difficult to scratch built  ( I did..... that says it all ) the bomb rack comes from Eduard set ref : 3005 

the difference between the E 3 / E4 is of course the angular canopy , the bullet proof armored plate behind the pilot's head , and the coaxial cannon which was different too

the Eduard 's bomb rack

The reason I ask, the filter aside, as it seems possible to build the E-3 from the E-4 boxing, and the E-4 from the E-3 boxing, just by switching canopies. That will work great for me, as I'd already started my E-4 kit, intending to do it as the aircraft above, posted by the OP (which may or may not actually be an E-4 anyway), and use the canopy sections from my newly acquired E-3 kit, then building the E-3 kit as an E-4, once again just switching the canopies.

Yes , we can !!!! ....as somebody said  however the   109 dépicted up there is a E 3 at the first sight

This type of supercharger intake can be found on most, if not all, of the 63 Bf 109 T-2 built by Fieseler between March and June 1941. The production of these T-2 aircraft was preceded by a batch of 135 E-7 machines produced between October 1940 and March 1941 (the last 109 E aircraft produced). So, it is possible some of those final E-7 machines produced by Fieseler also received this supercharger intake, and it further appears that a small number of other E aircraft was retrofitted with the intake from 1941 onwards. The machine Tolga wants to model may be one of those final Fieseler-built E-7s, but without knowing the W.Nr., this is impossible to say for sure. In any case, here you can find a couple of photographs of S9+GT, showing the Fieseler-type intake:

 

http://falkeeins.blogspot.com/2010/06/photos-of-wespen-bf-109e-7-jabo-sub.html

 

Vogt (2012) has suggested that this type of supercharger intake was nothing more than the intake designed for the E/Trop versions, minus the dust filter. However, photographic evidence shows this to be unlikely: photographs of E/Trop aircraft having the sand filter removed show that they just had the standard oblique E-type supercharger intake, with a rectangular sleeve added at the front to allow the transition to the dust filter. So, the Fieseler intake does seem to be a separate, new design.

 

I'm not sure what the reason was for this revised intake, but I suspect it may have been intended to improve the airflow to the engine, by providing a better 'ram' effect and doing away with most of the louvres in the oblique 109 E intake. In this respect, it is interesting to note that the Fieseler-type E intake is very similar (not identical) to a supercharger intake tested for the 109 F by Messerschmitt, and used on the 50 Bf 109 F-1 produced by WNF between November 1940 and January 1941.

 

As regards differences between the Bf 109 E-3 and E-4: the most obvious are of course the introduction of a canopy with rectangular cross-section and the addition of head armor in the E-4. In addition, the wing cannon in the E-4 were changed to the improved MG FF/M which was adapted to fire high explosive 'Mine' shells (E-3 used MG FF), and an improved pitch control for the prop. However, these latter changes are not visible externally.

 

With this, it has to be kept in mind that many surviving E-1 and E-3 machines were upgraded to E-4 standard during overhaul, with many E-4 aircraft subsequently rebuild to E-7 standard. At the same time, some E-4 and E-7 machines had the rear head armor removed, and sometimes even reverted to the older rounded canopy for better rearward visibility - this was mainly the case in aircraft used as nightfighters or Jabos. The bottomline is: without the W.Nr., it is often difficult to know as what E subtype a particular cannon-armed airframe was originally produced.

 

And finally, it is a common misconception that the E had an engine cannon; in fact, no operational series production E airframes were ever built with an engine cannon, and later produced E-4 and E-7 and E-8 machines have a pointed spinner lacking the central opening.
