The aviation industry has always been shaped by the constant strive for improvements and state-of-the-art innovations in order to combine an economical and ecological motivation with a relentless effort to ensure safety in our skies and contribute to the well-being of our society. By using revolutionary technologies, new aircraft projects can thus contribute to fight climate change and even assist in special and demanding operations like firefighting. INtelligent FirE RespoNse Operation (INFERNO) is a fleet of four Vertical Take-Off and Landing (VTOL) aircraft operating together interconnected and intelligently for efficient, next generation aerial firefighting with an expected Entry Into Service (EIS) in 2030. The project is part of the 2022 DLR Design Challenge covering the preliminary design as well as sizing and selection of the hybrid powertrain. For the development, extensive literature research, as well as textbook methods and detailed aerodynamic simulations were utilized. The designed aircraft is characterized by a considerable high payload ratio that features vertical take-off and landing capabilities while showing efficient horizontal flight properties with a very competitive cost basis. The 24 h operability during various weather conditions and during challenging fire scenarios is ensured using a wide variety of sensors and a modern glass-cockpit combining pilot comfort with indispensable safety aspects. Due to its modular design, every aircraft can be comfortably converted to a passenger or freight version during firefighting off-season or for cargo and crew supply during the missions.
