Ran across some interesting pictures of the Delanne 20-T to go along with the drawing and notes Justo Miranda posted.

Perhaps I can assist you. Here are the mentioned drawings from
the mentioned Le Trait d'Union issue.

With details,DL-120.

Fiction, "A Blunted Sickle" features
29 July 1940
...
"In France, the first flight takes place of the Arsenal-Delanne 10-C2 Biplane. It shows some interesting characteristics – notably the clear field of fire offered to the rear gunner and the ability to cope with a widely varying centre of gravity – but the low top speed of only 550 km/h is disappointing."

The Arsenal-Delanne 10 C2 was really built and was tested by froggies and germans.

Hi,

https://www.destinationsjourney.com/historical-military-photographs/arsenal-delanne-10/

For information, these photos are extracted from Jean Cuny's article about Maurice Delanne in Le Fana de l'Aviation issue 231. They initially come from Jacques Lebourg's collection.
I also attach 1938 english magazine publications showing interpretation of Delanne 10 fighter, in company of another unidentified english strange project.

The "unidentified English strange project" is none other than the Airspeed AS.31.

There is a topic on the strange bird AS.31 in Secret Projects named "Airspeed AS.31" ...

Here is an unknown Delanne heavy fighter or light bomber patent ?,also
the year is mystery ?.

 

[Arjen]

It could be a drawing of the Miles M.43

What makes you think this drawing is from Delanne - where did you find it?

 

[Stargazer]

It could be a drawing of the Miles M.43

Indeed!! I KNEW I had seen that shape somewhere but I couldn't figure out just where.
Yes, it definitely IS the M.43.

 

[hesham]

I think not,there are two differences in the drawings ?!.

 

[Apophenia]

Here is an unknown Delanne heavy fighter or light bomber patent ?,also the year is mystery ?.

That big-wing-at-the-back canard layout is sort of the opposite of Maurice Delanne's usual Duo-Monoplane concept.

 

[Arjen]

I think not,there are two differences in the drawings ?!.

Looks like a patent drawing. It would not be the first patent drawing that differs slightly from the final design.
Where did you find the drawing? The site/publication might provide additional information.
The general configuration looks far more like the Miles M.43 than any Delanne design, from the kink in the leading edge of the low placed rear wing to the forward swept trailing edge of the high front wing.

I can't remember from where,but I can't also find it in Miles patent,and
there's some similar in Delanne,

[Arjen]

In all of the Delanne designs I have seen so far the rear wing is smaller than the front wing. WW2 tandem wing aircraft designs with a front wing smaller than the rear wing point me in the direction of one manufacturer - Miles Aircraft. The planform of both wings in your drawing are a near perfect match for the M.43 as shown in my reply #51.

I rest my case.

 

[hesham]

I will open a topic for Delanne aircraft list.

 

[hesham]

From La Fana 229.

 

[PhR]

From Le Fana 230,here is artist drawing to a patent,and DL-10 wooden Model.

The artist drawing is not directly extracted from a patent. However, it illustrate the same initial configuration, as it appears in the patent filed by Delanne in July 1935. This design was modified and the beams between wings were removed in the wind tunnel model tested the same year. Arsenal de l'Aéronautique was commissioned to build the prototype, then known as Arsenal-Delanne or Air-Delanne 10 C2.

 

[Hood]

I know the Airspeed AS.31 has crept into this thread in posts above and is off-topic, but that patent drawing is interesting in that with the thin booms connecting the rear wing it is very much like the AS.31, almost as if the AS.31 was a tandem wing but with the aft wing shrunk back to the size of a tailplane.
I wonder if there was any cross-pollination in reality?

 

[PhR]

Various other designs from Maurice Delanne, recorded in multiple patents.

NB: Hesham, please DO NOT try to assign number to these designs. Most of them are just simple concepts, which do not correspond to any real project.

 

[hesham]

Here's the Delanne DL-40 project.

Excuse me, but are the dimensions of the Delanne 150, 151 and 160 known?

 

[Schneiderman]

In all of the Delanne designs I have seen so far the rear wing is smaller than the front wing. WW2 tandem wing aircraft designs with a front wing smaller than the rear wing point me in the direction of one manufacturer - Miles Aircraft. The planform of both wings in your drawing are a near perfect match for the M.43 as shown in my reply #51.

You are correct, and I don't know why people have found it so hard to locate the patent. It is indeed Miles, applied for in 1943, GB578978

 

[hesham]

Excuse me, but are the dimensions of the Delanne 150, 151 and 160 known?

For DL-150,

Span 18.20m ,length 12.7m

DL-160,

Span 11.54m , length 8.35m & height 3.47m
