Delanne Aircraft List

[hesham]

Hi,

Maurice Henri Delanne was born in the town of Diors in France early in 1901.
He grew up in the golden age of French aviation, the age of Warman and Bleriot;
of Fonck, Guynemer and Nunguesser. He received his degree at the famed Superior
School of Aeronautical Engineering in Paris, in 1924. Having some funds of his own,
he founded his own company, the "Société Anonyme de Recherches Aeronautique."
In this era the biplane was still supreme. Surplus equipment from World War I was still
available, so Delanne decided that what was needed was a high-performance, low-
powered personal aircraft. He realized that most of the planes available at the time
were overweight for their function; as a result, they had to use huge engines, with
proportionately large fuel appetites.

Early Designs,

D II was a side-by-side two-seat low-wing touring monoplane, powered by
one 70 hp Anzani engine,1929

# For Delanne with Westland or Pardel Development Corporation,there
are not a regular series,or I don't know,how their forms were ?.


- To be continued

 

[Stargazer]

"Warman"??!!
I suppose you meant Farman.

 

[hesham]

I start with a little bit designations.

 

[hesham]

Work is in progress.

 

[hesham]

I reach to D-300.

 

[hesham]

I finished it.

I am not convinced by this interpretation. I don't have documents about Delanne 300, but various ones confirming the Delanne 1300 designation, starting of course by the dedicated article in "Les Ailes" issued July 21st, 1961: https://gallica.bnf.fr/ark:/12148/bpt6k3201023c
This is the only source cited by Minijets site, despite the fact that it mentions only Delanne 1300 reference, and never "300".

Agreed. I could accept the idea of a typo if it was just a passing mention within a text, but the Les Ailes article has the designation in extra-large bold type on the front page as well as in the article itself, so it must have been correct.

Thank you,but please don't say that,because all of those concepts are
really existed,and mentioned in a many reliable sources,I ONLY guessed
what their designations ?!.

 

[PhR]

Thank you,but please don't say that,because all of those concepts are
really existed,and mentioned in a many reliable sources,I ONLY guessed
what their designations ?!.

In that case, please just list them as "unknown designation".

The patents are just concepts, not projects. So they don't had any designations.
Most of the other ones are just hypothesis about possible variants of existing projects, without evidences. By providing false designation to these hypothetical studies, you introduce errors in the history and create legends, which are very difficult to trrace and to distinguish from reality.

You don't know,and they are not all a patents,but most of them are unknown
Models,even a patents,they may got a designations,and we have generally
a thousands of these in huge number of companies,and there is a picture to
a collection of models,it contains more than six different concepts,and we
recognized only two from them.

Yes, I know this photo of collection of models and agree that some of them are unknown models.
I disagree when you suggest that Delanne patent drawings may have a designation. This is not the case.

 

[PhR]

You don't know,

Neither you.
For information, I have a part of Delanne archives, including some other drawings with no designation, as well as other ones completely different with the same designations. The history of Maurice Delanne is one of my projects.
