The Rogožarski R-100 (Serbian Cyrillic:Рогожарски Р-100, transliterated as Rogožarski R-100 in German and as Rogojarsky Р-100 in some older English sources) was a single-engined, single-seat parasol winged aircraft designed as an advanced and fighter trainer built by Rogozarski in Yugoslavia before World War II. About 26 were built, serving with the Yugoslav Royal Air Force until the fall of Yugoslavia in 1941. After that, 11 R-100s were used by the newly formed Air Force of the Independent State of Croatia, sometimes as ground attack aircraft, and one R-100 was used by the Italian Regia Aeronautica.
The Prva Srpska Fabrika Aeroplana Živojin Rogožarski A.D. was the first Serbian aircraft manufacturer in Yugoslavia, founded in 1924. In about 1938 they designed the Rogožarski R-100, a training aircraft with a single open cockpit in an oval wooden monocoque fuselage, a successor to their Rogožarski PVT. It came from the design team of Prof. Sima Milutinović. Its wooden, fabric-covered wings were slightly swept and parasol-mounted above the fuselage, attached with lift struts to the lower fuselage and with a central inverted-V Cabane strut. Its ailerons were full-span, narrow-chord, fabric-covered metal-structure units, with prominent spades above the wing's upper surface.
The R-100 was powered by a 420 hp (313 kW) 7-cylinder radial IAM K-7 license-built version of the Gnome-Rhône 7K radial engine, driving a two-bladed propeller. The engine mounting incorporated an NACA cowling. The forward fuselage was metal-covered from the engine to the 158-liter fuselage-mounted fuel tank, after which the fuselage was fabric-covered. The fixed, divided type undercarriage had a main shock absorber leg, its upper end attached to a steel attachment near the mid-fuselage, allowing the wheel to remain nearly vertical during deflections, whilst providing a wide track. The wheels were connected to the lower fuselage with a swinging V-strut. A steerable tailwheel was used.
