Abstract Currently, hybrid-electric aircraft are under investigation as one possible solution to reduce the emissions of aviation industry according Flightpath 2050 European Union. To meet drive train's requirements on low mass while aiming for highest efficiency, superconducting technologies regarded a key enabling technology train powers several tens megawatts. Within German nationally funded project TELOS an exemplary mission profile and physical measures 220-passenger used derive...
According to Flightpath 2050, the aviation industry is aiming substantially reduce emissions over coming decades. One possible solution meet these ambitious goals by moving hybrid-electric drivetrain architectures which require electric components be extremely lightweight and efficient at same time. It has been claimed in several publications that cryogenic particular superconducting can help fulfill such requirements potentially cannot achieved with non-cryogenic components. The purpose of...
Electric machines with very power-to-weight ratios are inevitable for hybrid electric aircraft applications. One potential technology that is promising to achieve the required ratio short-range aircraft, superconductors used high current densities in stator or magnetic fields rotor. In this paper, we present an indepth analysis of fully and partially superconducting based on analytical approach taking into account all relevant physical domains such as electromagnetics, properties, thermal...
The use of high-temperature superconductors in electric machines offers potentially large gains performance compared to conventional conductors, but also comes with unique challenges. Here, the electromagnetic properties superconducting bulk HTS trapped-field magnets rotor and copper coils stator are investigated. To this end, an analytical model field radial air-gap synchronous is developed validated, taking into account specific difficulties that occur treatment HTS. Using model, influence...
Die Luftfahrtindustrie steht vor grosen Herausforderungen. wachsende Anzahl an Passagieren bei gleichzeitiger Reduzierung der Emissionen erfordert die Entwicklung okologisch und okonomisch nachhaltiger Antriebssysteme. Elektrifizierung des Antriebssystems bietet aufgrund neuartiger variabler Konzepte, wie hybrid-elektrische oder verteilte Antriebe, Vorteile, diese Ziele zu erreichen. Infolge mehrfachen Energiewandlung muss ein solches Antriebssystem hocheffizient sein, um im Vergleich einem...
