У Кантини јавише да је са Батајнице полетео Орао. Вероватно баш овај из Моме. Smile

Letece Orlovi i G4(a i Gazele)jos dugo i cini mi se dok njih bude bice i kakvog takvog letenja jer se mi pitamo za sve radove oko njih kada su u pitanju produzenja resursa i zivotnog veka
Cini mi se da je cesto osporavana koncepcija oslona na domace potencijale sada poslednji tracak nade za prezivljavanje Srpskog RV
Verujem da tadasnji planeri i najveci zagovornici domace proizvodnje nisu ni bili svesni dokle ce to doci
Da smo tada nabavljali stranu tehniku,posebno zapadnu odavno bi to stajalo u korovu
To je i deo razloga zasto smo u lovackoj avijaciji dotakli dno

U Sloveniju stigao rumunjski Orao...paradoks svojstven ovim prostorima da zemlja koja je sudjelovala u razvoju aviona i operirala na svom prostoru sa tim avionima, dobije muzejski primjerak od Rumunjske, a ne od Srbije...ali ajde...

kada smo već kod rumunskog Orla, ovaj je uslikan na ulazu u Temišvar, na dosta neobičnom mestu reklo bi se...ali lep je bio osećaj videti "poznato lice" u nepoznatoj zemlji

Prvi prototip `Vultur` `001` sa 4 podkrilna nosaca



Pandan naseg prototipa J-22NS 25101, Prvi IAR-93B `Vultur` `200`



Citat:The IAR 93 Vultur (Eagle) is a single seat, twin engine, subsonic close support, ground attack and tactical reconnaissance aircraft. The program started in 1970 under original project name YUROM as a joint-venture between the Romanian INCAS institute and Yugoslavian VTJ engineers to meet requirements of both air forces.The two single-seat prototypes made simultaneous first flights on October 31 1974.The Yugoslavian aircraft was named SOKO/VTJ-J-ORAO.
There are many estimates as to how many IAR 93s were produced with figures ranging from 80 to 150.


The Romanian Air Force RoAF had a few large squadrons of IAR-93 comprising around 35 aircraft each.The plane was never a success, or at least the Romanian version.Although the same, the Yugoslavian ORAO ended to be perhaps better than the IAR-93 simply because they used all their resources well, as opposed to using simple factory workers to make the fuselage and other parts of the aircraft as it was the case in Romania.

The Iar-93 was developed in two stages: the IAR-93 A was the first variant equipped with the Rolls-Royce Viper Mk 632-41 turbojets.These engines had a thrust of 17,79 KN (4000 pounds of thrust) too small for such an aircraft.Due to lack of support from the russians, Romania turned to Great Britain for help.At the time the policy towards eastern countries was not to sell engines with a thrust greater than 4000 lb st and this is why the Viper was adopted for the IAR-93.This engine uses a lot of fuel, a lot of oil, has no pollution controlling capabilities, makes a lot of noise and is notoriously unreliable and under-powered and it's one of the reasons for the crashes of both IAR-93 and the ORAO.

The IAR-93 B was equipped with the Viper Mk 633-47 turbojets.These engines had a thrust of 17,79 kN (4000 lb st) but offered the advantage of having an afterburner installation offering 22,24 kN (5000 lb st) which was still less than needed.
Today the IAR-93 is no longer in service with the Romanian Air Force many of them finding rest near home, at Craiova Airport.Most of them have less than 5 hours of total flight time.

Rumuni su imali 5 prototipova ( 001 -005 ) 3 su izgubljena 001 ( 1979 ), 003 ( 1977), 004 ( 1979 )

Citat:Flight testing
The Romanian single-seat prototype White 001 made its first flight which lasted 21 minutes on October 31, 1974 at Bacău (simultaneously with the Yugoslav prototype at Batajnica Air Base). The aircraft was flown by Colonel Gheorghe Stănică. On September 20, 1979 the plane was lost when, during a test flight both engines stopped and the pilot ejected. This prompted modifications to the combustion chamber (including all aircraft already delivered).

On July 18, 1975 the aircraft was presented to Nicolae Ceauşescu on the Bacău airfield.

The DC (two-seat) prototype #003 first flew on January 23, 1977, and was lost on November 24, 1977 due to tail flutter. The left elevator broke off while in level flight at 500 m altitude and 1,045 km/h. The Martin-Baker Mk RU10J zero-zero ejection seats functioned well and the two test pilots ejected safely. After this event the aft fuselage structure was reinforced.

Prototype #004 crashed at Craiova Air Base on February 20, 1979 during an aerobatics demonstration. The pilot, Capt. Eng. Dobre Stan didn't manage to eject.

On August 23, 1979 three IAR-93 (#001, #002 and #005) were first presented to the public in flight during the military parade celebrating the national day of Romania at that time.
