Branislav Bilen

1931 - 2009

Branislav Bilen, long time professor and head of cathedra for shipbuilding at the Faculty of Mechanical Engineering in Belgrade and the director of the Institute of Technical Sciences of SANU (1981-2001), gave great contribution to the development shipbuilding.

He was given several awards and acknowledgements such as the October Award of Belgrade, medallion Kirilov, four gold medals Eureca in Brussels and others. Based on his rich experience from practice in the shipyard “Tito” (later “Belgrade”), where he was engaged in project design and testing of ships, and later in research and development, new solutions were developed, especially in shipbuilding, hydrostatic devices, shaft generators, pumps, modernization of friction radial connections, steering mechanism, devices for selection of sand and rudders from water. He solved the problems connected to launching and dragging out the ships and platforms for boarding and unloading trailers and containers in ports. According to Bilen’s projects, 120 port tugboats have been constructed up to 1700kW, which entered into the expert literature as the first port tugboats with one propeller.

Professor Bilen, as an inventor, was active for the full two decades. As a result of his R&D work in the Institute of Technical Sciences SANU, he created more than 30 patent applications, in particular 17 patents in Serbia and 14 abroad, and some of them are in USA, Great Britain, Romania, Poland, Hungary and Italy. The first European patent granted to the applicant from Serbia – EP28586B, was granted to the Institute of Technical Sciences SANU for the invention of Branislav Bilen and Nenad Zrnic, referring to the “Device for the separation of sand and/or rubber from water at the exit of the tubes of refuler dredge pumps or for the separation of other granulates from the stream of fluids”.
