Dewoitine D.500/D.501/D.510 technical information

Recommended Posts

Hello everyone, whilst I was rummaging around the stash I happened across a couple of Heller boxes, one for the D.500/501 and another for the D.510.

I've been looking for sites that have technical data on the types but they're a bit thin on the ground, I've found this thread here http://www.britmodeller.com/forums/index.php?/topic/31732-british-dewoitine-d510-l4670/ and the link off of it to here http://translate.google.com/translate?hl=en&sl=es&u=http://www.network54.com/Forum/394728/thread/1237702339/DEWOITINE%2BD510&prev=/search%3Fq%3DAERONET%2BGCE%26hl%3Den%26client%3Dfirefox-a%26rls%3Dorg.mozilla:en-GB%3aofficial%26hs%3Depj (sorry about the length of the link but I don't make up the url's), which has some useful stuff.

Most of what Mr Google turns up isn't detailed enough and is invariably the same old stuff.

Does anyone know of a site tha contains some useful technical information such as cockpit views etc?

It's a future project.

Olivier,

Just taken the time to look through the thread in the link you posted, very helpful I must say. Thanks for posting.

Hello there

I would like to build a silver French D510 from the Heller kit. Were these planes left in NMF or were they painted silver?

Holy thread resurrection Batman!

 

It's hard to pick out much tonal variation on the metal surfaces but then again, if all the metal surfaces were made from the same material you're unlikely to see any.

 

My guess and it is only that, is that the metal surfaces were natural metal and the fabric surfaces silver dope.

 

Hopefully somebody will come along with more information.

I agree with Wez. On some photos slight variations in colour can be noticed:

Aluminum surface seems to be less shiny in those days. Higher percentige of magnesium in alloy, perhaps? Cheers

According to the maintenance and repair manual (Notice d'Entretien et de Réparation) Duralumin was varnished.  No colour is specified but, as Jure points out in post 10, there is some variation in colours so I would guess it was a transparent varnish. Duralumin was aluminium alloyed with copper, not magnesium.

There is some useful information on this site -

Scroll down and you will find the manual.  The relevant paragraphs have been outlined in red.
The complete manual is here -

This other manual, Notice Descriptive et d'Utilisation, has drawings of more interest to the modeller.

In fact it is with both: copper and magnesium (though less amount then copper) also less manganese and silica.

BTW I have personal experience in dissolving duraluminum in acids and the small silica addition becames very obvious during dissolving and required use of HF to remove a kid of brown mud-like substance...

Hello

 

We used to call Duralumin as AU4G => (AlCu4MgSi).

Thanks for your comments.  I wrote "Duralumin" with a capital D as this is the word used in the in the 1937 manual for the Dewoitine D.500.  Duralumin (upper case D) is a trade name for one of the earliest hard aluminium alloys which I believed used only copper.  It has certainly been improved with other additives in the intervening years.

Indeed, I was  surprised when I've read in Britanica, that name cames after some name, so far I thought that "dur" cames from latin as for this alloy hardered properties ("dura"="hard"),  so a bit  funny...
