UAH PD Solutions - Nitrous Decomposition Hazards

Online On-Demand | 4 hrs | $299

Join internationally recognized subjectmatter expert, Arif Karabeyoglu, Ph.D. to explore safety issues and steps to properly utilize N2O. Recently, hybrid rockets have started using Nitrous Oxide (N2O) as a propellant. Explore the potential hazards of N2O used in propulsion systems. N2O is considered much safer and easier to work with than liquid oxygen. It is more forgiving in terms of the temperatures it is kept and how it operates. Even though N2O is widely used, the number of decomposition related accidents are quite limited due to its abnormally slow decomposition kinetics. However, hazards do exist, especially in propulsion systems where large quantities of N2O are stored at room temperature in thin-walled vessels. The tightly coupled combustion chamber is a significant source for ignition which does not naturally exist in other applications. Explore the safety issues and the steps to properly utilize N2O with emphasis on propulsion systems. Prerequisite: Undergraduate degree in a technical field or equivalent experience.

Meet Your Instructor: Internationally Recognized Subject-Matter Expert: Arif Karabeyoglu, Ph.D. Dr. Karabeyoglu earned his Ph.D. in Aeronautics and Astronautics from Stanford University and is currently a faculty member in Mechanical Engineering at KOÇ University, Istanbul. He served on a board that investigated the SpaceShipTwo (SS2) accident caused by the uncontrolled decomposition of N2O and on the board of advisers for the development of the SS2 propulsion system. He is a Principal Investigator for several projects related to the safety of N2O for commercial space applications. Dr. Karabeyoglu holds several patents including a pending patent in “Mixtures of Oxygen and Oxides of Nitrogen as Oxidizers for Propulsion, Gas Generation, and Power Generation Applications.”
