Virgin Galactic’s suborbital space tourism vehicle (SpaceShipTwo), which is based on hybrid rocket propulsion, has recently started powered flight testing and expected to fly passengers in the near future. This would be the first substantial application of the hybrid rocket technology which will lead to the utilization of a large number of motors each year. Despite its historical significance, SpaceShipTwo’s nitrous oxide (N2O) and polymeric fuel based hybrid motor delivers a moderate Isp performance and expected to have a relatively low fuel utilization. Recent technological advances made by Space Propulsion Group Inc. (SPG) have resulted in the development of high performance hybrid rockets without compromising their simplicity, cost and safety advantages over the solid and liquid propulsion systems. The new liquid oxygen based advanced hybrids deliver 330-340 seconds of vacuum Isp with better than 98% fuel utilization. It is believed that this new promising technology can be quite enabling for advanced suborbital systems (including space tourism applications) and also for orbital missions.
Dr. Karabeyoglu is the President and Chief Technical Officer of Space Propulsion Group, Inc. He has received his Masters and Doctorate degrees from Stanford University. He is a full time faculty at KOC University and also holds a Consulting Professor position at Stanford University. Dr. Karabeyoglu has performed extensive research and development activities in the field of chemical propulsion and green energy with emphasis on the creation of new concepts and their implementation to real life systems. He has been the Program Manager and Principal Investigator for a wide range of programs for clients such as Air Force, NASA, FAA, Navy, and Scaled Composites. Dr. Karabeyoglu has actively participated in a number of accident/mishap investigations including the Scaled Composites Tier 1B accident. Dr. Karabeyoglu has numerous journal articles, conference papers and patents. In addition, he has authored a book chapter on the instabilities in hybrid rocket propulsion systems. In addition, Dr. Karabeyoglu has started a course on Advanced Rocket Propulsion at Stanford University which he has been teaching since 2005. He also has been co-instructing an AIAA short course on hybrid rocket propulsion. He has served as the chairman of the AIAA's Hybrid Technical Committee during the period 2009-2011. Dr. Karabeyoglu is a member of the American Chemical Society and an Associate Fellow of the American Institute of Aeronautics and Astronautics.
