Arrow A Salmson engine?

.
Hello!

A while ago I found this photo. As far as I can see a German soldier is inspecting the valves of a liquid cooled radial engine. The scores of tubes and pipes lat me assume that this a Salmson engine attached to the fuselage of a Voisin pusher type aircraft.

Iím not an engine specialist. So, has someone a more precise idea?

Hello Volker .

I believe this motor is the Water cooled Radial , Salmson M9 ( Canton-Unne) 120 ch . ....and the machine was a ( STAe ) .. Voisin III .........[ factory] Voisin LA or LAS .

You can see the (bent) central strut goes up & connect with the top/apex of the Rear inverted "V" strut of the Cabane .
On the left bottom is seen one of the Coils Springs for one of the Rear landing gear struts .

Yes, definitely a Salmson Canton-Unne. All the 9 cylinder engines M9, P9, R9are very hard to distinguish externally but, this one I believe is probably an M9. As John states, the aircraft is more than likely a Voisin III - I think probably an LAS - due to the positioning of the carburettors.

Question Quick answers...

.
Thank you for you quick and well-founded answers!


As already said I'm not a specialist for aircraft engines and so the concept of this engine (liquid-cooled and radial) puzzles me.

In the early days of aviation "weight" and "low performance" were two of the main enemies of the aircraft engineers and the air-cooled rotary engine was a good solution to overcome this problem. Also air-cooled inline (or V-type) engines were known and successfully used in this connection. So why did the Salmson company develop a relativey heavy and complicated liquid-cooled radial engine? In my opinion it would have been easier to achieve the same performance with a "normal" inline engine...

Volker: Early radial air-cooled engines tended to be of low power or high in fuel consumption. The Renault/RAF family of aircooled vee engines had high rates of fuel consumption. The stationary aircooled radial engine was clearly a goal of designers, but dealing with the problem of high heat production and metallurgical problems were very slowly overcome. The rotary engines, while high in fuel consumption, in effect made much of their own cooling by the rotary motion of the engine.

The Anzani engines were something like proto-radials, but were of low output. The Salmson was heavier than an aircooled radial, but in the years in which it was used there simply were no stationary aircooled radials that approached it in power and efficiency. Ransom
