Pre-Concept Performance Investigation of Electrically Powered Aero-Propulsion Systems

摘要

Motivated by the possible prospect of zero in-flight emissions and the observed progress and perspectives in key electrical technologies, the pre-concept performance assessment of electrically powered aircraft propulsion systems is presented. The efficiency potentials of Electric Fan (EF) and Electric Open Rotor (EOR) power plant architectures are assessed and compared to advanced turbofan technology. In multi-disciplinary sizing and performance studies at the isolated propulsion system level, and, at the integrated vehicular level, optimum power plant design constellations are determined. Requirements for battery systems are derived, that would enable universally-electric, mid-size, short range air transport.
