Comparison between different configurations in hybrid aircrafts based on design approach

This paper reviews recent developments in hybrid-electric propulsion systems and their applications in four categories of aircraft: hybrid airships, hybrid electric airplanes, hybrid drones, and hybrid air taxis. The design concepts, propulsion architectures, operational advantages, and technical challenges of each category are discussed. The study shows that hybrid-electric propulsion can significantly improve fuel efficiency, reduce emissions, and lower noise levels compared with conventional aircraft. However, limitations related to energy storage, system weight, and thermal management remain major obstacles. Future research directions include propulsion optimization, advanced energy management, and thermal management technologies.
