Special Issue Information

Dear Colleagues,

Electrified aircraft propulsion is a key enabling technology for achieving net zero emissions in air transportation. As in automotive systems, various electric and hybrid electric architectures, including hydrogen-based systems, have been proposed for aircraft propulsion.  In addition, significant advancements have been made in regular and flying cars and eVTOL vehicles as air taxis. This has been possible with the advances in electric machines, power electronics, energy storage systems, systems integration, control, and thermal management. The airborne vehicles' electrical components and systems must meet stringent power density, efficiency, reliability, and safety requirements. This Special Issue on “Electric and Hybrid Electric Aircraft Propulsion Systems” invites original research papers that address the challenges and opportunities in the following topics:

  • Electric, hybrid, and distributed propulsion system architectures;
  • Hybrid energy storage for electrified aircraft;
  • Electrical machines for propulsion and for on-board power generation;
  • Power electronic converters for propulsion motors and for on-board power generation;
  • Electric power management, distribution, and protection;
  • Superconducting technologies (including cryogenic cooling systems);
  • Electrical system control, diagnostics, and health monitoring;
  • Fuel cell systems for propulsion and on-board power generation;
  • Hydrogen engine-based propulsion;
  • Power and propulsion system modeling and simulation;
  • Propulsion systems for eVTOL and flying cars;
  • Other impactful technologies.

Review papers may also be submitted.

The current trend in distributed electric aircraft propulsion systems is to utilize the DC bus system at higher voltage levels than conventional aircraft systems. With Boeing and Airbus utilizing the +/−270 V bipolar DC bus system, the research on high-voltage systems is increasing gradually, with voltage levels ranging from 1 to 10 kV systems or +/−0.5 to +/−5 kV DC bus systems. These voltage levels present considerable challenges to the distributed electric aircraft propulsion systems. In addition to partial discharge effects, there are other challenges, particularly the challenge associated with effectively limiting short-circuit fault currents due to the low cable impedance of the distribution system. The cable impedance is a significant factor that determines the fault current during fault conditions. Due to the low impedance, there is a sharp increase in fault current, necessitating an enhanced protection strategy, which ensures that the system is adequately protected. This paper introduces a coordinated protection strategy specifically designed for distributed electric aircraft propulsion systems to mitigate or prevent short-circuit faults. The proposed algorithm utilizes an I2t-based strategy and the current-limiting-based strategy to protect the system from short-circuit faults and overload conditions. Redundant backup protection is also included in the algorithm in case the circuit breaker fails to operate. Full article
