military companies and managing small companies and foundations. Dr. Rohacs delivers lectures on numerical methods, numerical optimization, aerodynamics, flight mechanics, and control and development philosophies. He has an extensive practice in project management, including investigation, research technology, and product development. He was involved in many EU-supported projects (over 26 international projects), including EPATS, Sat-Rdmp, Sinbad, Pplane, Esposa, Innovate, SmartPolis, Nelui, and others, and coordinated the EU L1 level project, Gabriel. He is the professional and technical manager of the national project IDEA-e, developing the technology for electric and hybrid-electric propulsion systems and conceptual design for the 4-seater electric and hybrid cargo UAV aircraft.

Daniel Rohacs, Ph.D., is Head of the Department of Aeronautics and Naval Architecture at the Budapest University of Technology and Economics (BME). He served for the Research Development and Simulation Department at HungaroControl - Hungarian Air Navigation Services as the head of the department for many years. He worked for Eurocontrol (Bretagny) as a doctoral researcher for three years as a Ph.D. student at École Pratique des Hautes Études, Sorbonne (2004 - 2005), and visiting Ph.D. student at Princeton University. He has good management practice as a research director of SME Rea-Tech Ltd (since 2006) and CEO of RDS-X Ltd. (2005 - 2007). Dr. Rohacs is very active in international cooperation and research, including the EU-supported projects EPATS, Sat-Rdmp, Sinbad, Pplane, Esposa, Innovate, SmartPolis, and as project manager of L1 Gabriel project, USIS SESAR UTM, SafeFly, IDEA-e, and special projects at HungaroControl, including the introduction of free-routing and remote tower concepts into operation, developing new ideas, disruptive technologies, and solutions. He is active in international conference organizations and participates in IFAR (International Forumfo
