Rules

The thread title must be "Bréguet's aircraft ID challenge #......"
The score board, link and rules must be copied to the beginning of each thread, so that we know where we are. The score board and the correct answer to the challenge must also be placed at end of each thread.
The completed aircraft must have been either; designed, built or have left the ground during the '14-'18 period and be identifiable by the poster.
The photo must show the whole aircraft - from whatever angle, or at least 2 views of a 3 view drawing (photo by preference).
Challenges which depict a machine already earlier presented are disqualified (always check the list at Aeroplanes 1914 - 1918* -* Breguet's Aircraft Challenge* -- when in doubt !).
If there is any doubt as to the eligibility of an aircraft for the challenge details should be PM'd to Breguet BEFORE the aircraft is submitted.
Once someone has got 5 correct answers under their belt they become an ACE. Once they become an ACE they must wait 12hrs after the posting of the new challenge before they can post an answer.
To be eligible for correct ID an answer must include at least one characteristic of the aircraft that helped in its identification.
The first person to ID the challenge correctly gets to post the next challenge. If this can not be done for any reason Breguet himself will post the next challenge.
If an ace gives the correct answer too early, the challenge is over, he gets no point but has to post the next one. In lieu of the fact that the "novices" have in effect been "cheated" of their "exclusive" time that next post should be a relatively easy one. Anyone repeating the correct answer at the right time gets neither a point nor the right to post the next challenge.
The final arbiter in relation to questions about the rules will be Breguet.

Previous challenges can be found here :

Aeroplanes 1914 - 1918* -* Breguet's Aircraft Challenge* --

And the new aircraft is :

[Aquilius]

By the engine cowling front, propeller mounting and the single struts, this must be the Rumpler D.I (Typ 8D 1)!

It was the only fighter designed and ordered from Rumpler and should have had an incredible climb rate but only 49 were built in 1918. Powerplant was a Mercedes D.IIIa or BMW IIIa.

Aquilius

[Lodzermensch]

Hi,

It looks like Rumpler 7D4 because of single inter plane strut, forward part of fuselage, cut out in upper wing and side radiators.

Cheers

Marek

PS I forgot unbalanced ailerons.

[Lodzermensch]

Hi,

This may be Rumpler 7D7 at a pinch, because bracing cables look thick.

Cheers

Marek

Correction - this is Rumpler 7D7.

[Aquilius]

Hi Marek,

didn't the 7D 4 had two conventional struts on either side?

While you gave a different attempt I looked into the previous prototypes again.

There was also the 7D 7 which is characterised:

7D7 - similar to 7D4 but with wing bracing again using I-struts (this time of narrow chord) and the bracing wires simplified. The flush-mounted radiator in the wing was replaced by ear-style frontal radiators on the forward fuselage

I'm not sure about the ear radiators, but I believe they are placed above the lower wing like in the production type 8D 1 (D.I). There is a bracing at the landing gear - so not the 7D 8.

Anyway, I stay with my attempt. We'll see what Richard will tell.


Cheers

Aquilius

[Lodzermensch]

Hello Aquilius,

The answer is in a book Edmund Rumpler - Wegbereiter der industriellen Flugzeugfertigung by J.A. Kranzhoff (I have not checked it previously of course) - page 319.

Regards

Marek

Hello :

The ID of the prototypes of the RUMPLER D I is not easy ,as you know .

I rely on Peter M Grosz ID for this picture :
the little radiators just over the lower wings are those of the RUMPLER 7D7

So ,congratulation to LOTZERMENSCH ,who get the point and have to post the next #718 challenge .

Thanks for participation
Richard
