engines - first half of 30's

With pleasure. But - may I ask about their e-mail address?

See my other post (before yours) I updated it a few times.
Mr. Cicos is active on this forum so I guess he will show up here sooner or later.

Let me 'fine tune' a bit the translation.

It actually asks the Polish military attaché from which source did the Poles secure the licence rights of the Mercury engine: through Bristol, in England, or Gnôme & Rhône, in France, as well as the price.

What type of motors were installed on the tri-motor Savoia-Marcheti, manufactured in Romania under license? Were they originals from Italy?

Yes, I know. But the rest of this story is more interesting.
Romanians could buy Bristol engines licence with the Polish assistance not later then in 1932.

Hi Florin,

If I remember rightly, the Italians adopted the tri-motor configuration for the SM79 (and several other bombers) because their own engines were underpowered. However, the Romanians wanted to fit their own more powerful IAR 14K and this allowed a redesign of the SM79 for the Romanian order as a bimotor. So I guess that the answer to your question is that Romania's initial Italian-built bimotor SM79s had Romanian-built engines.

There is a chart of Romanian engine developments in the 1930s and early 1940s in the book "Third Axis, Fourth Ally".

Cheers,

Sid.

You have to agree that the bimotor looked waaaaay better than the trimotor

From this site :


and



However, was not the Jumo the choice for the engines? Instead of the k14?

S.M. were powered by K14 and by two variants of Jumoe engines.

Zayets, you posted the <<"long nose" variant>> . The variant with "short nose" - is much uglier... In my eyes, at least.

Hi Zayets and Iamandi,

Yes. I have always thought the bimotor Romanian SM79 was aesthetically a great improvement on the original Italian trimotor and the long-nose better than the short nose. If the tail was a little more attractive I might almost consider it beautiful!

Cheers,

Sid.

JRS-79 was the Jumo version: Jumo-Romanainan-Savoia-79.

I love the way she looks anyway, just wish we could fly this in Il2

And JIS-79 was,obviously, Jumo Italian Savoia

First models came from Italy - before our own modified SM-79 were produced by IAR factory. Also, the italian planes were to be fitted with 2 engines - the romanian configuraton and I do not remember very well but I think those two engines were indeed Jumo.

The airplane was much appreciated, so it was decided to buy the license to produce 36 new Savoias at IAR Brasov. However, the new bombers were also going to be fitted with the more powerful Jumo 211 Da engines and the task of redesigning the aircraft for to incorporate them was too much for the experience of the Romanian engineers. Eight of these new airplanes were ordered in Italy. They were designated JIS-79B (Jumo Italian S-79B). But they didn't arrive until August 1941.

Hi!
I`m not so good with engines,but,for S79 Romania send the engines in Italy for the first 24 airplanes.
Romania bought the licence from France for K7,K9 and K14 but also a large number of engines from GR.The licence for Bristol Mercury was not finalised,I think.In 1943 where some discutions with germans to have licence for BMW 801 engines to be made at IAR,but finaly they give licence for DB 605 engine.If IAR had licence for BMW engines and use them on IAR-80....
In 1939 arrived from Poland an PZL-11C Kobus with an Bristol Mercury VIII engine but romanians where not intrested in this engine,and it was changed.

Interesting. Do you know more about Romanian "career" of the P.11g (not P.11C!) Kobuz?

Here is what I found in a document dated 1945, regarding licence of Bristol engines:

Translation: we have the licence rights for the [Bristol] Pegasus IM3.
The search continues...
