That would be Ernest Zens.
Therefore the Zens monoplane. Can't find a designation as such on the Aviafrance website.

Ernest and Paul built a successful monoplane in 1910.
The harvester is clearly a biplane and is from 1908.
But I will not split hairs on that as I made the mistake of posting a non-flying machine.

Noyade has control.

It clearly is! I have no idea why I typed the word 'monoplane.' :ugh:
Thanks for the leniency SLB - but I'll stand in the corner and offer Open House.

As it was only a typo from your side,
I have no problem that you would post the next challenge.

OK.Thank you.
I've not much in the cupboard, so I'll try this one again...

Lordy! Whay is this? A Windy Dragbus?
They could at least have area-ruled the fuselage!


It smells Italian to me...?

At previous posting I came as far as thinking it is probably a triplane?

I also wondered about a triplane and since there appear to be radiators on the sides of the fuselage, I wondered about a racing triplane.

I know, it sounds stupid, but it turns out there was one - the Curtiss Cactus Kitten:

A bizarre history - started off as a monoplane, then a biplane and finally a tripe!

Yes, a failed attempt by me to crop out the third wing. :)
Nicely done India, over to you.

Great find, Noyade.

You would think they would have made some attempt to streamline the radiators! Looking at that ultra-coarse pitch prop, I assume it wasn't a STOL machine. :E

Open House.

Shall we extend the current challenge by requiring to post at least two other aircraft types with side mounted radiators? Including photos please.

If somebody takes the open house that is also fine with me.

Well, here is one obvious one for you. :ok:

And here is one with the radiators a bit more streamlined. :ok:

Two nice examples but to my opinion, Using cowlings is cheating!
I have to admit that when I started searching there were more hits than expected:

I know these pipes are the oil cooler, but the S-6B is what made me think to look for a racing triplane.

While looking for a suitable picture, I stumbled on this amazing website:
https://johnkshelton.********.com/20...mitchells.html

Since PPRuNe hates this particular domain for some unknown reason, here's a workaround:

I love Mitchell's description of the S-6 as a "flying radiator".

That made interesting reading, India Four Two, and made me realize I am not much of an aircraft designer !

I read that Mitchel solved the takeoff problem of the torque submerging the LEFT float by making the RIGHT float larger.
Surely a mistake I thought: you should make the left float larger to give it more buoyancy.

However, Mitchel also moved fuel out of the left float and into the right float so the anti-torqu moment would remain after lift-off.
I now think my solution would have resulted in lift-off into a half roll and spectacular splash ! :ugh:

I've always thought that the pilots of these float planes were very brave men. Does anyone have any idea of the length of the takeoff run for the S-6B?

The picture Terry posted of the engine being installed in the S-6B makes you realise how large the engine was for such a small airframe. Imagine a Cessna 150 with a smaller wingspan and a 2350 HP engine! :eek:

I see no more other examples forthcoming, so I think it is time to go back to the Open House
my examples were:

Some art work this time...

Very pretty!

Noyade,

Are we looking at a biplane?
