By designing and building a hybrid electric motor glider, the FVA student club aims to investigate the benefits of alternative propulsion concepts with unconventional configurations for small aircraft. The project highlights the potential of hybrid-electric powertrains in general aviation and validates the feasibility of their implementation by building a fully functional technology demonstrator, the FVA 30. The design goals comprise both performance requirements for efficient and cost-effective medium-range operation as well as ease of manufacture and maintenance. Particular attention is paid to safety to demonstrate the technologys maturity for everyday usage. The FVA 30 uses a serial hybrid power train that generates thrust via two electrically driven propellers integrated into a V-tail. A range extender provides constant power corresponding to cruise flight requirements, while temporary power peaks during take-off and climb are covered by a high-performance battery system, which additionally allows for brief battery-electric operation. The range extender employs a bivalent fuel system which may incorporate conventional gasoline as well as methane gas as primary energy sources to further reduce CO2 emission. This paper gives insights into the general design process, aircraft properties, and preliminary conclusions. The FVA proceeds with the construction and flight-testing of the FVA 30.
