Hi Imalko,
I hope you can help me. I'm conducting a research of yougoslav air force pre and during WWII and I have come across an article entitled Kraljevacka fabrika "Brege" which is written in serbian that I cannot translate also in said article there is a picture of a twin eingined bomber that I cannot identify.
I'm attaching a picture of this aircraft hoping that you will be able to identify it. Also with a separate message I will send you copy of the full URL.
Cheers and thanks in advance

Hello Carson!
I will have to check but think I have this entire article, it was published in Aeromagazin few years back. Its quite long article but I suppose I could translate it for you but it will take some time (don't know how long though).
As for twin engined aircraft on the pic its Dornier Do 17K. It was licence produced in airplane factory at Kraljevo and served in Royal Yugoslav Air Force as light bomber.

I was thinking about starting new thread dedicated to the Yugoslav Air Force in WW2 years. Actually I have plenty of interesting material on this subject but translating all this is very time consuming.

Also if you are interested in this subject you may want to check out this link:

Cheers!

I found the article... It was published in AERO magazin issue 51 from august/september 2003.
Here's a quick translation of the text which is refering to the picture on the page you have posted:

Do 17 was intended for day and night bombing and recconnaisance and it was equipped with two 870hp air cooled piston engines with a compresor. Regardeless if they were imported or manufactured at Kraljevo, all Dorniers were armed at Kraljevo factory. In the nose of the aircraft was placed 20mm automatic cannon Hyspano and in the windshield 13,2mm Browning machine gun. Besides in bomb bay, bombs could be carried on two hard points bellow the wings, one of the configurations being - 2 x 200kg beneath the wings and 8x100kg bombs in bomb bay. Aircraft had a crew of three.
Performance: ceiling: 8500m, combat radius: 800km, max.speed: 425km/h for bomber version and 438km/h for reccon version.

Profile from book: Dornier Do 17 - the Yugoslav story (Operational Record 1937-1947) written by Boris Ciglić Dragan Savić

Hi Cromwell thanks very much for the nice pic of the P/51 Reno Racer.Regarding the Fairey Battle I agree, it was certainly a Fairey P/24 engine that drove the contrarotating props (By the way your pic of the Fairey Battle with contrarotating props must be a rarity, thanks for posting)

Sorry Verner, the Yokosuka R2Y1 used two eingines to drive one single six blade propeller therefore no contrarotating props (her look fooled me too!)

It's named RP-4, has a futuristic look and promise to beat the "World 3, 15 and 100 Kilometer Speed Records".

Hi Marcogrifo,
thanks very much for your precious contribution, I didn't expect any less from you! I'll include this contraption (it rather looks like a grassmower) in my next list.
If you think of something I may have overlooked or ignored you are welcome to let me know.

Yes Sireeee !!

No B/S - I really think there is a Gap in the Market for a book on Contra-rotating Propeller Planes

Go get 'em Carson - you could sell it on Amazon maybe ?


Take care

Aha ! the F35B Version has a CONTRA-ROTATING FAN !!

Quote from :


United Kingdom Announces F-35 Joint Strike Fighter Supersonic Stealth Jets Purchase | 24 Plus News


" Compared with the Conventional Take-off and Landing (F-35A) variant already flying, the F-35B has a shaft-driven lift fan mounted behind the cockpit, roll ducts installed in the wing and swivelling nozzle fitted to the engine.


In STOVL mode, doors open above and below the lift fan, a clutch engages to drive the two-stage contra-rotating fan from the engine and the rear nozzle pivots downward to deflect engine thrust."

Hi Marcogrifo,
I just read the Coonfield blog concerning the RP/4 racer of David Rose: it is incredible what a single man's ingenuity can accomplish and I regret having called it a lawnmower! It is instead an incredible accomplishment (just think of both tandem V/8 engines driving contrarotating props of carbon fibre at a speed exceeding Mach 1).
Do you know whether it flew already?I also like his name Rose Peregrine!

Hi Cromwell,
thanks very very much for the cool material you are submitting, it'll take me a while to digest the whole information mass!
I have very much appreciated the nice pic concerning the british Seagull ASR (only two actually flown), your 4th pic and the 5th diagram instead refer to the Douglas XA2D1 Skyshark(only 12 built)which is already available on my first listing.
You will hear from me hopefully within a short time (I'm an old man and must manage my time!).
Cheers and thanks again

Hi Carson

I looked on your list and you have the Douglas Y\B-42 and Douglas XB42/A o'Mixmaster" (1942) and Douglas XTB2D-I *Skypirate" (1945)

However, I don't see the XA2D1 Skyshark - Perhaps you can confirm please ?

Hi Cromwell,
you're right, how stupid of me! The Douglas "Skyshark" will be reflected on the new revised list I have in preparation ready next week.
Thanks

BTW I see us as friends and compatriots in our quest for the the ulitmate contra-list

Please don't feel you have to castigate yourself - I think we are on an adventure with many twists and turns before we reach our destnation.

I am looking forward to your new list - MkII no less
