manual gnome-rhone 14m

[Er Presidente]

14m, then evolved in 14k never managed to overcome the 800 cv wall, despite the 1000 seemed discounted.
all versions over 900 cv were very unreliable.
I don't have certain information about what problems they'd arise, but it would seem that the vibrations were the biggest problem.
studying this manual would be interesting to be able to discover the "tallone d'achille" of this project.
the only "solid" version was the one built by the isotta fraschini, but immediately abandoned after the first prototypes in favor of the piaggio that had acquired the same license.
the if version was deeply revised in the structure and eventually weighed even more, so some structural intervention had considered it necessary.
I personally consider the choice to maintain all the distribution of the two stars commanded by the same front, opinable and hole of potential "unequalities" between them and which could be the basis of vibration problems.
Even the "discomposed" carter does not seem very solid as a solution, we will see later if the competitors and/or the version if they had different choices.
the if was famous for its expertise in large aluminium castings, derived from the experience in its monoblock headboards, but it is not said that this is the difference.
a comparison with American "radials" will be necessary, also because they were able to reach 2000 cv without particular problems (structural, others, "to iosa").

it will be because of lubrication to castor oil! :tongue:
If I understood well the engine was lubricated with castor oil, while transmissions with mineral oil, right?
I knew that castor oil was used in the two days but I didn't know that they used it in the four, it was normal practice for the time?

Bye.

interesting consideration.
lubrication had a violent evolution at that time and even b-29s had embarrassing problems in the first year of service due to the lubrication. However, lubrication was normally due to gripping with subsequent fires.

Castor oil "burns well" without slinging the condels, oil consumption on these engines was "important", almost two times, using an oil with good combustion characteristics was mandatory.

Go on like this, dotto. :finger:
that for now I read, but above all I look, and then a postdomain I could also begin to ask a few questions. :biggrin:

p.s.: yesterday I sent a couple of pictures of the heads to my client who has another company specializing in casting and processing of headboards, especially for motorcycle engines.
because they also make cylinder bodies and alettate heads for air-cooled engines, I told him: "look and shine your eyes."
Caxxo!!! he told me that today in Europe will be at most 5 or 6 foundries able to realize (bene) tested and cylinder bodies like those of the drawings.
think of you as we are, after almost 80 years... :frown:

thinks that the design and layout of the alettatures was the result of huge studies and patents.
an almost forgotten art.

 

[Er Presidente]

I think we have some more precise idea of the object.
interesting is the presence of an elastic joint between the compressor and the motor shaft, a ski boot.
other note should be made on the presence of a parafiscal system in the suction manifold.
Let's keep an eye on the engine shaft, it'll be one of the biggest defendants.

 

[Er Presidente]

Let's start with the distribution.

double coaxial recall spring, "fit" roller, scale on bearings.
Not bad for being in the 1930s.

you could try a translation ... only that would serve a control by those who the French technical language really knows it.
In truth, a French engineer I know him, he worked a little years at the antaldo and in January he returns to France and goes to work for these here:http://www.snecma.com/?lang=fr

That would be really great.
It's not the best.

ocr recognition of the document is very good.
I reported in word the first 36 pages you posted.

I didn't bite!
less bad than I've 2scanned" to 600 dpi.

translated well we could create the "clone" in local idiom.

notice the frontal graft of the central pinion, probably for use in phase.

I don't know if the view deceives me and if it's a visual effect but to me it seems a localized fracture (bial type) perhaps dictated by processing problems

I've seen you. It's so regular that it looks like a mating system.
we wait for the next pages of text to see if it makes the description

with the present I come to askle :smile: politely attach urgentment:redface: the reproductions of the "planks", the final tables listed on page 10, where there are the balls with the numbers that correspond to the bold ones that read in the text during the description of the various components. are indispensable. . .
For now, at least those from iv to iv would be needed. I think you'll have to photograph them, because they'll be far beyond the a4 format.
