After the war, Ikarus, Zmaj and Rogožarski factories were heavily damaged due to the Axis bombardment in 1941 but also after the Allied bombings in 1944. Most of the equipment was also gone and around 1000 of the workers perished in war. Luckily, the designers and technicians managed to keep some of the plans so the Aero 2 and S49 (Ik3) planes could be built.
Ikarus who was merged with Zmaj and Rogožarski continued the production of aircraft untill 1961. You have to understand that because Yugoslavia wasn't in the NATO or Warsaw pact the defense doctrine had to consider both these alliances as potential enemies. The defense was based on massive partisan resistance and the relocation of key defense factories in Bosnia. Thus, after 1961, most military planes were built in Soko (Falcon) factory in Mostar. Some of the biggest construction projects in Yugoslavia were top secret underground air bases and command centers. A few billion dollars was poured into them and the construction took a few decades in some cases. One of the notable projects was Željava underground Air Base near Bihać with several levels and elevators for fighter aircraft (Yugoslav companies built several bunkers for Saddam Husein in later years). The other big project was Atomic War Command, built in mountains near Konjic.It could house several hundred people at one time. Željava was destroyed during Yugoslav civil wars but ARK is in pristine condition and open for tourists (everything is in place,from Tito's war cabinet to Bosna soaps produced in 1970 ;D )
This paragraph tried to explain why there were no projects after 1961. The Ikarus still lives and produces buses. They had to change their name to Ikarbus in 1992 due to the fact that there is a bus manufacturer named Ikarus in Hungaria. I believe that there exists Ikarus aircraft manufacturer in Switzerland or Germany who produces ultralight planes.
Ikarus prewar office building still exists in New Belgrade, now surrounded with apartment blocks (untill early sixties, Ikarus factories and Belgrade airport were situated in New Belgrade - prewar old airport hangars and Airforce command bunkers in nearby Bežanija hills still exist; modern Nikola Tesla airport was built some fifteen kilometers further west, in Surčin municipality)

Ikarus 214 - twin engine multipurpose plane (light bomber, transport, parachute training),post war project of aircraft designer Sima Milutinovic. 22 were built from 1949 to 1959)
Ikarus 215 - twin engine multipurpose plane, 1 prototype built in 1949
Ikarus 451 - light attack aircraft, one prototype,fitted with 2 Walter Minor 6-III piston engines and a prone pilot cockpit.
Ikarus 451M - (Mlazni - Jet) Derived directly from the S-451 airframe, the S-451M substituted Turboméca Palas turbojet engines for the piston engines, in underslung nacelles at the same positions on the wing and conventional cockpit.
Ikarus 451M Zolja - (Zolja - Wasp)light training aircraft; Flown in 1954, the S-451M Zolja featured a stretched fuselage,folding wings, and engine nacelles centred on the wing chordline. Used to set a world speed record in its class in 1960.
Ikarus J451MM Stršljen - (J - Jurišnik - close support) (Stršljen - Hornet)The intended production close support version with tricycle undercarriage, Turboméca Marbore engines and cannon armament.
Ikarus Š-451MM Matica - (Matica - Queen bee, Š - školski - school) Two-seat trainer version, used for a world speed record in 1957.

Ikarus Student - tourist plane, one prototype,1952
Ikarus 522 - single engine transitional plane, 2 prototypes, 1952.(Soko Mostar built 112 planes until 1962 (due to similarities, this plane often played FW190 in partisan movies, I'm not certain about Kelly's Heroes appearance because Yugoslavia had P 47D's)
Ikarus Kobac - (Kobac - sparrow hawk)two-seater wooden glider, one prototype,1953
Ikarus Košava - (Košava - name of the wind common to the Balkans, two-seater wooden glider,2 prototypes, 1953.

Ikarus Meteor - single seat metal glider, 2 prototypes built, 1958
Ikarus Lightning - two-seater wooden glider, 1 prototype, 1958
The pictures show the Ikarus office building, plaque on it that commemorates workers who died in WW2, old airport building and MIG 21 in underground base (I'm not sure if it's from Željava or Slatina air base near Priština).
