ELECTRIC DRIVES FOR SPACE VEHICLES AND SATELLITES - PART I: ELECTRIC REACTIVE DRIVES

koje će održati (on-line)

prof.dr.ing. Ognjan Božić

znantvenik i istraživač German Aerospace Center (DLR)

 

dana 20. travnja 2021. s početkom u 16:00 sati

Abstract:

The series of lectures begins with an introduction and review of applications and needs for electric-kind of drives in space technologies. The topic of this lecture emphasize the intention of application and issues of electric kind of drives applied to the space vehicular technology. First of all it will be dealt with the characteristic featuers and parameters of electric drives with concluding point in application of electric reactive-kind of electric drives with examples of: north-south satellite orbital correcture and discussing on transporting techniques for LEO and GEO payloads, Lagrange's L1 and L2 also. Also, lecture will discuss the issue of Space-thugs in mission of removal of space junk.

 

Biography:

Hon. Prof. Dr.-Ing. Ognjan Božić received his PhD from the Technical University of Braunschweig in 2002 with a dissertation related to CFD modeling of heterogeneous multiphase combustion processes in steam generators.

Božić spent 20 years as a researcher at the German Aerospace Center (DLR) – Institute for Aerodynamics and Flow Process Technology, Braunschweig, Germany (until his retirement in December 2018). His work focused on chemical rocket propulsion, aero-thermodynamics of space vehicles returning to the Earth’s atmosphere, rocket flight mechanics, systematic analysis of space launch systems as well as the development of electromagnetic accelerators (MHD and RAILGUN). Božić started teaching as an assistant and assistant professor in the field of defense technologies at the Faculty of Mechanical Engineering, University of Sarajevo MFS), Republic of B&H and continued his career at the Technical University of Braunschweig, Germany (since 2010). He is currently an honorary professor of teaching space propulsion at TU-Braunschweig in his master’s studies. He has also been involved in many experimental projects such as the X-38 Crew Rescue Vehicle (NASA), ESA Expert Capsule and SHEFEX 1 Suborbital Capsule, as well as several feasibility studies such as “Sample Return Mission from the Moon” (study leader) , MHD propulsion and Liquid Booster with the possibility of a soft return to Earth (LFBB) for the Ariana 5 launch vehicle. . He is a member of the British Interplanetary Society (BIS, GB), Deutsche Gesellschaft für Luft und Raumfahrt (Supervisor of the Solid and Hybrid Propulsion Committee DGLR-Germany), Adriatic Aerospace Association (Croatia) and a full member of the International Academy of Astronautics (IAA) based in Paris . Prof. Božić is also the author of over 70 books and scientific papers published at international conferences, congresses and in refereed journals.
