Ikarus Aero 2

The Ikarus Aero 2 was a piston-engined military trainer aircraft built in Yugoslavia in the years following World War II, although the design pre-dated the war.

Development
It was designed in response to a Yugoslav Air Force requirement for a modern, monoplane trainer to replace the Fizir FN biplanes then in service. The powerplant was to be the de Havilland Gipsy Major because of its successful use in similar trainer aircraft built in other countries.

Ikarus' entry, designed by Boris Cijan and Đorđe Petković was selected over its two competitors in trials held between June and November 1940, but production did not take place until the Air Force began to rebuild itself after the war. 248 were eventually built, serving from 1948 to 1959 (380 built according to.

Design
The Aero 2 was a low-wing monoplane that seated the student and instructor in tandem, open cockpits (although later versions added a canopy to enclose them). Undercarriage was fixed and used a tailskid.
