Bratu projects

[Caravellarella]

Here is an updated list of Payen's designs. I compiled it using mostly this thread and the great Payen page at AviationsMilitaires.net and found it pretty impressive that Payen did so many designs over his long life yet produced so few actual aircraft.

Early collaborations and non-standard designations

Br.220 Bratu three-engined monoplane (Payen worked as an engineer) (1930, not built)

Bratu 220, son train d'atterrissage se rompit aux premiers roulages d'essais

Do you know if R.N. Payen was the designer of the Bratu twin-boom? (axial 4-engines double-push-pull, pod and above)
from an Aviation Magazine of 1976:

Isn't that the Br.250 which appears in the list?

The famous (built) Bratu-220 is illustrated at

but (from Trait d’Union 162 July-August 1995) I add here the -221mention (different wing spars) and -250 model (twin-fuselage with 4 axial engines):

From an unknown issue of Air Enthusiast, article tittled "Paper darts to deltas, the designs of Roland Payen" by Alain Pelletier:
Quote: Payen alo participated in the preliminary design of the twin-boom, four engine Bratu 250, but the Bratu Company dissapeared as quickly as it has been born.".

Caravellarella, you're right, the update for the Bratu 220 was made on AviationsMilitaires.net but not on Secretprojects.

Here the link about the Bratu 220 on Aviafrance :

Bonjour
A Bratu patent , from "L'Aéronautique , 6/1932"

And from my dear Tophe,


a patent drawing for it.

 

[hesham]

the -221 mention (different wing spars)

Here it's.

Here it's.

Translate of Bratu 221,

Before the completion of the 220 model, Bratu had begun building
two examples of the BRATU 221, which differed from the 220 in its
wing design featuring conventional spars. The expulsion of the Bratu
firm from the Athis-Mons workshops led to the abandonment of the
construction work already begun.

It could be easy to imagine a bomber concept from it.
