Here's a CGI image of the YCA (Yugoslav Combat Aircraft) from a Dassault brochure via Flateric (thanks!)

Novi Avion (New Aircraft) 1992

Type: Single-engined, single-seat, multirole combat aircraft and two-seat operational trainer.

Program: Yugoslavia's indigenous successor to the Mikoyan MiG-21. Design definition completed by Vazduhoplovno Tehnicki Institute (VTI) in early 1990 assisted by several Western aviation companies, notably Dassault. Discussions with European and US firms on possible collaborative airframe development and possible use of Rolls-Royce, General Electric, or Pratt & Whitney powerplants. Intended manufacture by Soko. All work was reported to have ended in 1992.

Cost: Estimated development expenditure $150-to-$200 US dollars per year throughout 1990s.

Design features: Mid-positioned, delta wings with 46 leading-edge sweep and 3 trailing-edge forward sweep; canard foreplanes with 45 leading-edge sweep; single fin with inset rudder; no horizontal tail; twin "Rafale-type" kidney shaped intakes for high angle-of-attack performance; low-set cockpit. Rates of turn sustained 20/s; instantaneous 30/s.

Flying controls: Digital fly by wire (FBW) control system; two-section elevons form entire rear surface of wing; movable canards.

Structure: Widespread use of carbon composites, Kevlar, aluminum and aluminum-lithium alloys, titanium and other advanced materials.

Landing gear: Tricycle-type with single wheels; all retracting forward into the fuselage.

Power plant: One engine in the 100 kN (22,480 lb st) class. Internal fuel capacity 3,300 liters (871 US gallons; 726 Imp gallons); external tanks for further 5,800 liters (1,531 US gallons; 1,276 Imp gallons).

Accommodation: Pilot only, under three piece canopy; 17 downward view over nose.

Avionics: Nose-mounted radar; digital flight control system; multi-function nav/attack system; secure communications and advanced cockpit displays.

Armament: Eleven hardpoints, including two for wingtip infra-red AAMs and one for cannon up to 30 mm; maximum individual bomb size, 1,000 kg; precision guided bombs and missiles.

here's another view, with few pressclippings, 3D model and a aerotunnel model.


On this blog, you could find additional pictures from aerotunel testing.

Some great wind tunnel model pics on that blog, including the early ventral intake version and the later "Rafale Lite" version.

Regarding the engine, I have read on another blog that the SNECMA M88 was the strong forerunner, not least because there was definite interest from South Africa for it to power the Atlas Carver. The French would turn a blind eye to what would have been a big order. The blog goes on to say that the deal was effectively scuppered as Yugoslavia wanted far too much to facilitate the deal. So much in fact, that it would finance a great portion of the Novi Avion project.
 
Not sure how true this is though, although both aircraft were broadly similar in role and timeline.

At first, they wanted to do everything alone, the second phase was the cooperation with Dassault (engine and avionics, but not the CATIA software) the third phase was the inclusion of India in the deal (similar to the joint cooperation with Romania on the Orao ground attack aircraft).
Yugoslavia invested heavily in the modernization of its civilian and military research institutes in the eighties as preparation for the production of NA (a few billion dollars in 1990 exchange rates, including new Mach 4 tunnel). I have a 20 page article, split in three about the pressclippings from the late eighties and early 1990s about the project.  The intent was to invest a few hundred million dollars annually for ten years. I've never found any source that says the France would fund the project.
The big question is, how would this aircraft fare on the world market today? If it could be cheaper than Grippen and share no problems with the engine and electronics procurement like J-17 had? How many countries have outdated fleets and have no money for the Rafale or the upkeep of the older fighters?
There is another aspect of the YU-FRA relations from that time, the Aerospatiale's efforts to sell Super Puma instead of the homegrown VNH - 90 project.

While browsing through various magazines, I came across an article from the Yugoslav Aero Magazin N2 dated March/April 1998. I don't speak Yugoslav but it seems like the article describes various stages of a program known as "YU-supersonic". Several pictures illustrate the article, among which two models depicting the so-called YCY (presumably Yugoslav Supersonic Fighter) in two different configurations. Then two wind tunnel models appear, one taken in Zharkov, the other in India.

Here is an advertisement for the so-called "Novi Avion" ("new plane") that appeared in Aero Magazin N3:

Here is the Novi Avion thread, including drawings with a ventral inlet.

Earlier drawings of Novi avion were made before the cooperation with France. Later pictures show a lot of similarities with Rafale.
Aircraft technical institute (now part of military technical institute) is situated in Zharkovo, a municipality in Belgrade. The concept was similar to TSAGi, they designed,built and tested the plane. After that, state aircraft factories such as Ikarus, Utva an Soko produced the aircraft.
There is no Yugoslav language. For a good part of the 20th century it was called serbocroatian (in Serbia) and croatoserbian (in Croatia). Nowdays it is popular that every former Yugoslav republic has it's own language and church. Slovenian and Macedonian language are slightly different but understandable. People in Croatia, Bosnia and Herzegovina, Montenegro and Serbia speak the same language.There are three dialects and the main difference between them is whether you put a few letters in specific words (example: milk - mleko, mlijeko,mliko).
Anglosaxon parallel would be for instance the existence of Canadian,American, Australian and Newzelandian language.
Although the differences are minuscule compared to the German-swiss german or portugese-brazilian portugese we now have four different languages on paper. Sad.

I know that it looks extremely confusing to foreigners (and when you add the fact that for example Serbians use two dialects out of three,plus there are two writing systems in use (Cyrillic and Latin)  the confusion is complete). But the fact remains, if you learn one combination (dialect/writing system) you'll be able to communicate with everyone without problems.
Back to the subject, Yugoslavia invested heavily in basic research, material science and the procurement of machines intended for the research and development of the novi avion.
Here's the wikipedia article of the aircraft technical institute with a few pictures of the facilities and wind tunnels.
