Various Yugoslav Post War Projects

[hesham]

Yugoslavia aircraft:
LIBIS KB-11 Branko :four seat all metal low wing aircraft,retractable
u/c and 185 hp Lyc O-435-1 engine.
Vajic V.55 :a tandem two seat light aircraft with a strut-braced high
wing, fixed tailwheel undercarriage and 85 hp Walter Minor
II engine.
Government Factory Pionir :a prone pilot experimental aircraft powered
by two 55 hp Walter Minor III inlines engines.

In this thread I'll post pictures and info about projects that weren't part of three major aircraft factories: Ikarus Belgrade, Utva Panchevo and SOKO Mostar. They were mostly gliders and small sport aircraft but there are a few gems nonetheless.
Fizir Fa-2 was the last project of the aircraft designer Rudolf Fizir and the further development of the prewar Fa-1 design. It was designed to meet the requirements of the Horvat Aviation Association for a small four man amphibian suitable for passenger transport along Yugoslav coast and islands. The plane was made of wood in order to allow for limited production in small facilities. The prototype was nearing completion in 1955 but was never finished and Fizir died in 1960. It would have used one Lycoming O-435 195hp engine.
Span: 12m
Length: 8,34m
Empty weight: 800 kg
Loaded weight: 1250 kg
Max speed: 205 km/h
Cruising speed: 175 km/h
Landing speed: 90 km/h
Ceiling: 3000m
Range: 550 km

Now here's a real gem. Since today is my fourth year on the forum, I'll post one extremely rare bird. B)
KBL-12 would have been the first jet aircraft designed by a Slovenian, engineer Marjan Slanovec. It would have been built in LIBIS factory (Letalski Institut "Branko Ivanus" Slovenia - Aircraft institute Branko Ivanuš). This 1954 project for an all metal aerobatic plane was the only project from the kbl series that wasn't built. Others were gliders and sport aircraft. A real shame.
Span: 6,5m
Length: 7,32m
Height: 2,65m
Empty weight: 355 kg
Fully loaded: 700 kg
Max speed: 510 km/h
Cruising speed: 450 km/h
Range (at 3000m): 450 km
Range (at 9000m): 900 km

Hi bigvlada,


can you post the Fizir Fa.1 in your pre-war thread?


Thanks, Maveric

 

[Stargazer]

Thanks for sharing, bigvlada. A rare gem indeed!

 

[Jemiba]

Very interesting indeed, many thanks !
Just a question: The upper side view and split top view shows an
alternative or earlier layout ?

 

[robunos]

Thanks, bigvlada, the Fzir Fa.2 looks a lot like the Lake amphibians...


cheers,
Robin.

Hi,


when I look for LIBIS aircraft,I found that,LK-1 was a high-wing four seat
tourist aircraft powered by one 160 hp engine,and KB-5 Triglav III first
Yugoslavia plane with V-tail,does any one get a drawings to them ?.

HI Hesham
In October 28 2006 you have noticed
the Libis kb 11
He is here from an old " aviation magazine"

 

[hesham]

Thank you my dear Toura,


and that company began from KB-1 Triglav sailplane up to KB-22,and it built
and designed sailplanes and light aircraft.

 

[bigvlada]

Photographs from paluba.info forum, taken at Partner 2013 fair, wing tunnel and scale models of Soko J-22 Orao.

 

[hesham]

Also from Aetosvet 06-07,


here is the FAJ A-25 and a small info about FAJ family,and a canard aircraft called Napravite Patku,and
a light aircraft called Najbolje Tricikl.

 

[bigvlada]

FAJ stands for Fabrika aviona i jedrilica - Aircraft and Glider Factory, Vršac (JAT pilot academy is situated there).
Napravite patku means build a duck.
Najbolje tricikl does not mean anything; najbolji tricikl means the best tricycle, they probably meant the best project with the tricycle landing gear arrangement. If you could post the whole page, I might be able to identify the models.

 

[hesham]

Sorry Bigvlade,I don't know this language.

 

[hesham]

From Aerosvet 09,


here is an aircraft project,but I don't know what was its real name ?,they wrote
PA-86 ?.

 

[bigvlada]

np hesham, just ask


This is not a real project, just a reader (who is also a model maker) submitting his drawing of how the ideal agricultural plane should look like and some basic characteristics.

Poljoprivrednik means farmer, and the 86 is probably the year of publication, similar to Moma 86.

 

[hesham]

Thank you Bigvlade,


and excuse me,the language.

 

[Stargazer]

Some really interesting designs here, thanks hesham.

 

[Maveric]

Nikolic NI.17

 

[Maveric]

Nikolic NI.18 (both from Janes 1964/65).

 

[hesham]

Great find Maveric,


and those two projects was belonged to UTVA,and I mentioned them before,here;


http://www.secretprojects.co.uk/forum/index.php?topic=16794.msg7475#msg7475

 

[bigvlada]

That's Utva Pelican, land and maritime version, Branislav Nikolic was the designer.

 

[Maveric]

The N.I.18 named "Delfin".

 

[hesham]

Maveric,


can you tell us a more info about NI.17 and NI.18 projects.

 

[Maveric]

No, I have only the technical data.

 

[hesham]

OK Maveric,


what was it ?.

 

[bigvlada]

Hesham already posted this article a couple of years ago, I'll just add some explanations, from said article.
http://www.secretprojects.co.uk/forum/index.php/topic,2943.msg84497.html#msg84497
SOKO ELH (Eksperimentalni laki helikopter - Experimental Light Helicopter) was designed in order to beat the Lynx; top speed was supposed to be 410 km/h at the altitude of 4000m. They have manufactured the Gazelle helicopter under license for almost 20 years and they intended to use as much as possible of it's technology in the new design. Main rotor was to be used only in hovering or in low speed (less than 100 km/h) modes. If proven promising, they wanted to implement this design in other types of helicopters. The construction of the first prototype was scheduled for 1993 and the first flight was expected in 1994.

 

[hesham]

Many thanks to you Bigvlada.

Hi,

here is a SkyPickup high-wing light transport twin boom Project.

From Ailes 19/5/1956,

here is the Fa.2,but with different configuration.

 

[hesham]

From Krila 1/1984,

here is a Slovenian designer,Egidij Grzinic created an autogiro,and we know by that time it was
under Yugoslavia union,am I right in translate ?,I used google.

Hi,

the LIBIS 520 was a twin engined low-wing business monoplane Project of 1956;

[hesham]

From Krila 3/1984.

first time to hear about BLOKE Pajo airplane ?.

 

[robertino]

pajo

 

[hesham]

From Krila 2/1990,

I don't know this aircraft,Branko Dezman.

 

[robunos]

While I can't read the article, the aeroplane looks like an Evans VP-1 with a bubble-top cabin . . .

cheers,
Robin.

 

[Aubi]

Homebuilt airplane built by Brano Dežman. They call it volksplane, and Volksplane is name for Evans VP-1 , so... It is exactly what robunos said.
