Design and development
The SIM-VI was designed by engineer
Variants
- Rogozarski SIM-VI – with 37 kW Walter Mikron engine
- Rogozarski SIM-VI-a – with 44 kW Walter Mikron II engine
Immediately after completing the flight tests of aircraft SIM-VI, engineer Milutinovic undertook the repair of the shortcomings he had observed, so that by the end of the 1937 Rogozarski had a new variant of this airplane which was designated SIM-VI-a. It had a more powerful engine Walter Mikron II 44 kW (60 hp). An increase in engine power required strengthening of the basic structure which Milutinovic used to make general improvements to the aircraft. Wing relative thickness was increased from 6% to 15% which strengthened the wings, and resulting in the removal of wire ties. Now the wings were covered with cardboard to the half swing instead of cloth which resulted in an improved overall stiffness of the aircraft. This also enabled the landing gear and aerodynamic characteristics of new aircraft to be upgraded, while the weight was only slightly increased.
Operational history
After successful testing and registration (YU-PDX)[4] the SIM-VI was bought by the Central Administration of the Aero Club, which used the it at airshows and for the training of sport pilots. The aircraft did not enter serial production because it could not be used at smaller and under-equipped airports that existed in central Serbia.
