Hi all
Here is the Coanda of 1911 which appears at the "Concours militaire de Reims"
(I've found it on "PPRuNE silhouette challenge")
Who know more ?
Thanks

Technically, I'm not quite certain this type qualifies as a "biplane". Monoplane is more like it...

Would agree, as the landing gear axle was often cased with an airfoil section. Counting it as a wing,
would turn the famous Fokker Dr.I tri-plane into a quad plane.

The ""Coanda biplane""
I try to found !!

 

[Stargazer2006]

Very interesting! The text says that this aircraft started off as a biplane but was eventually entered as a monoplane for the military competition.

Actually, it was the Concours Militaire (Military) version that was the biplane. and the monoplane version was a "Type Monoplane du Course" (racer version). They simply left off the lower outer wings. Both versions were available with the twin, side mounted 50 hp or 70hp Gnome rotary motors linked to central drive. This is from Original 1911 Coanda Catalogue.

Brilliant contribution, Joe, as usual! I wish you could post more often...

HHi all

From "Le Fana" et "aviation magazine"

SIA is not the name of the plane, it is the name of the company which built it:
Société Industrielle d'Aviation - Etablissements Delaunay-Belleville, with premises at Angers and St Denis.
[font=arial, sans-serif][/size]It had expertise in construction out of Duralumin alloy. [/font][font=arial, sans-serif]Henri Coandă worked there during WW1[/font].

[/size]
[/size]I wonder if the plane is their entry to the 2Bn competition ?

[/size]PS: in the title, Belleville should be spelled with 4 "L", for future searches, please

[hesham]

From AFM13,

Before applying his discovery to a circular shape, Coanda had imagined
a propellant made up of successive horns, each accelerating the air of
the previous one. This model shows one of the possible applications of
this airplane imagined in 1932.
