Rogožarski SIM-VIII
The SIM-VIII (Serbian Cyrillic:СИМ-VIII) was a 1931 Yugoslav, single-engined, 2-seat, sport, tourist and training aircraft, designed by Sima Milutinović and built at the Rogožarski factory in Belgrade from 1931 and by Ikarus at Zemun from 1933. Design and development The SIM-VIII was designed by Sima Milutinović at the end of 1930, with a desire to contribute to the development of aviation in Yugoslavia. The prototype was built at the expense of the constructor and the first test flight was conducted at Zemun in the Autumn of 1931. After certification the aircraft was purchased by the Yugoslav Royal Air Force and the Yugoslav Aeroclub at Belgrade. The SIM-VIII was a parasol winged monoplane powered by an Siemens-Halske Sh 14 engine driving a wooden 2-bladed propeller, seating two crew members in tandem open cockpits. Construction of the SIM-VIII employs several new construction solutions designed to reduce cost and streamline production, without compromising aircraft ...

Propeller (aircraft)
An aircraft propeller, also called an airscrew,Beaumont, R.A.; ''Aeronautical Engineering'', Odhams, 1942, Chapter 13, "Airscrews". converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type. The propeller attaches to the power source's driveshaft either directly or through reduction gearing. Propellers can be made from wood, metal or composite materials. Propellers are most suitable for use at subsonic airspeeds generally below about , although supersonic speeds were achieved in the McDonnell XF-88B experimental propeller-equipped aircraft. Supersonic tip-speeds are used in some aircraft like the Tupolev Tu-95, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1930s Yugoslav Military Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar.

Rogožarski Aircraft
Rogožarski () was a Yugoslav aircraft manufacturer. History Officially established on 22 April 1924 under the name of ''Prva Srpska Fabrika Aeroplana Živojin Rogožarski'' ( en, First Serbian Aircraft Factory of Živojin Rogožarski), the factory was responsible along with Ikarus for most of Yugoslavia's air industry between the world wars. Initially, the factory repaired aircraft confiscated in the First World War, and soon started to manufacture local aircraft, and licensed manufacture as well. Nationalised in 1946, the factory was merged along with Zmaj into Ikarus which continued in the aeronautical industry until 1962. The factory Rogožarski has made a total of 286 aircraft.

Rogožarski SIM-XII-H
The Rogožarski SIM-XII-H (Serbian Cyrillic:Рогожарски СИМ-XII-Х) was a Yugoslav trainer single-engine floatplane, with two floats designed in 1938. It was designed and built at the Rogožarski factory in Belgrade. Design and development The YRAF was unsuccessfully trying to choose the most appropriate seaplane for pilot training so they turned to the Rogožarski factory for help in 1937 and ordered the seaplane school project to be made that would fit in its characteristics to the school plane SIM-X. Since it was not possible to make a simple modification (adaptation of existing aircraft SIM-X) for installation of EDO floats, chief designed Sima Milutinović fitted the plane with a more powerful engine Walter Major 6 190 hp, leading to an increase in aircraft size. Thus, this new high-flying school plane with two floats represented an entirely new plane, designated SIM-XII-H. During 1937, the project went into realization stage, and as early as the end of ...

Rogožarski SIM-Х
The Rogožarski SIM-X ( Serbian Cyrillic: Рогожарски СИМ-X) was a Yugoslav single-engine sports and tourist plane also used for basic training of military pilots designed in 1936, with two crew members. It was designed and built at the Rogožarski factory in Belgrade. Design and development The SIM-X was designed by Sima Milutinović at the beginning of 1936 drawing on positive experiences of its predecessors SIM-II and SIM-VIII. The prototype was designed in the Rogožarski factory from August to the end of the 1936. The first test flight took place in 1936 when the aircraft was also registered by Rogožarski factory under the code ''YU-PDY''. After detailed test flights had been performed, it was offered to the Yugoslav air force for further tests, which were carried out at the Novi Sad school for pilots. The committee found certain minor flaws but, other than those, it was given an exceptional rating. The SIM-X which was intended for civilian use, sport pilot ...

Rogožarski AZR
The Rogožarski AŽR ( Serbian Cyrillic:Рогожарски АЖР) was a single-engined, two-seat biplane aircraft designed as a trainer in Yugoslavia before World War II. It was designed and built at the Rogožarski factory in Belgrade. Design and development William Schuster, a flight engineer, designed the AŽR at the end of 1929.
