Inline engined IAR 80

QUOTE

Ok now they are there..seeing anything yet ?

OK now. Thanks!

Hello,

Do you have any pics of the first prototype with open cockpit ? I have only one. I'd like to see more of it. :wink:

It was a very top aeroplane at the time it was built. 1935 Howard Hughes flew 550 km/h with HH1 and that was the fastest time ever clocked by then.

Indeed there are some photos with the prototype. It were published in several aviation magazines and in a book entirely dedicated to the plane unfortunatly in Romanian only. We are waitting for the French version that has some late at the publisher.

I can scan some of these pictures if wanted.

Yours,
BM

Yes Bernard,

Yes please I would very much like to see them or at least a few of them of your choosing.

best regards,

Juke T

Reportedly, of poor quality and quite expensive (22,50 USD):

Thank you Denes for this new info. Didn't know that it existed. I'll try to find it here. The price is quite low (even if the quality is not good) for such a limited in number model kit.

Yours,

I know i'm bringing up another old topic again , but i'm pleasantly suprised to see that someone else heard of the IAR-1500 engine !
All i know and can remember it's from the "Romanian aircraft factories during the interwar years ".

Started in 1939, in 1940 the supercharger ( rated at 6000m) and one cilinder were built. Rest of the story is more perplexing , something about the engine project being sent to Gnome Rhone who built it for the germans or similar, i can't remember exactly. Don't think i believe that part much though.

I cant remember the weight and cubic capacity of the engine ( think it was slightly over 40 litres, maybe 42?), but there was a comparison table of IAR-1500 with Gnome Rhone 14R and ASh-82 if i remember correctly .
Question is , this IAR-1500 engine project really existed or is just commie propaganda ?!

Gnome Rhone 14R was a 1500 hp engine developed in France, basically a 14K with a two-stage supercharger. This was abandoned after the fall of France because it was forbidden by the armistice. I am not sure that this had anything to do with the IAR factory. There is a story that one was tested on a IAR80, but this is unsubstantiated in the absence of any documents or photos.

Six 984 kW (1,320 hp) Gnome-Rhône GR14R engines were intended to serve into the (unfinished) protoype Me 323V17.

All 198 Messerschmitt Me 323 were using Gnome-Rhône radial engines. This spared a bit the overwhelmed German industry. Most of them were Gnome-Rhône GR14N radial engines rated at 738 kW (990 hp). It is a good question if the Gnome Rhone 14R mentioned by you was intended by the Germans only for the prototype Me 323V17, or it reached some other Me 323 as well.

I don't really know much more about this engine other than what Google can provide.

Neither me.
I started a search after reading in your post "...This was abandoned after the fall of France because it was forbidden by the armistice." I knew that the Germans used the Gnome-Rhône radial engines for Messerschmitt Me 323, but I was aware that those had 1000 HP each.
I read this:
http://en.wikipedia.org/wiki/Messerschmitt_Me_323
So, as the Germans wanted to fit the prototype Me 323V17 with six Gnome-Rhône GR14R engines, I think the story was: Armistice in June 1940, with a stop in the development of French military projects. Later, basic needs reminded to Germans that French aircraft industry is good after all. As the factory started to roll out hundreds of GR14N radial engines at 738 kW (990 hp), the engineers reminded that they have blue prints for something better.
It is just a good question if the only intended usage for the GR14R of 984 kW (1,320 hp) was for the Me 323V17 prototype, because in the link it is mentioned:
"...The Me 323's powerplants were of differing models of the Gnome-Rhone radials, depending on which wing panel they were mounted..." This of course could refer to the two versions of the same engine, clockwise and counter-clockwise, like in P-38 etc.

If this is true , and given what is said to have happened with the DB-605A powered aircraft, ie the germans saying they can't give us any engines because they don't have enough for themselves , probably a logical assumption would be either the romanians found out about the GR 14R engine , or the germans told them about it and said "look , we can't give you DB-605, but here , try this engine out , similar to your K, marvelous performance on the MB-157 etc etc ."

If i remember correctly there were some important defence contracts in those days with the french, for the Maresal engine for instance ( from Hotchkiss) , maybe there were some discussion re: GR-14R aswell ?

BTW the closest " 1600hp " one is probably the Gnome-Rhone 14R-4 used on MB-157 , aparently it delivered 1230 hp max normal and 1580 hp in "surpuissance" ( WEP ).

The weight of it is stated at 820kg, so probably would not have been THAT difficult to mate it with the IAR-80. ( unlike BMW-801 for instance which aparently weighs over a ton )

Just some thoughts.
