The Japanese team, centered on Kyushu University, is developing a high-temperature superconducting propulsion system for aircraft, taking advantage of its strengths such as low AC loss technology. One of its features is that the motor and generator are developed as fully superconducting rotating machines, which consist of superconducting windings for both field and armature coils. Next,...
An overview of the “IZEA” NASA University Leadership Initiative (ULI) will be presented to provide context for several other presentations describing details and progress under specific ULI tasks. IZEA addresses removal of carbon emissions for regional aircraft with ~120 passengers, 5000 km range, cruise speed of mach 0.8, and total power 25 MW by using liquid hydrogen fuel. Design of low-loss...
Turboelectric distributed propulsion (TeDP) is one concept which has been explored in the development of all electric aircraft. TeDP allows for the motor and generators to be decoupled from one another and connected through a DC cable distribution network. This enables various airframes to be explored such as the blended wing body (BWB) which allows for greater aero dynamical performance...
The growth in the aviation sector has highlighted the need to decrease carbon emissions, a significant factor in climate change. Hydrogen is a potential alternative fuel due to its high energy density, and its combustion mostly results in water. The use of hydrogen fuel cells further eliminates nitrogen oxides emissions, making hydrogen a zero-emission energy source. However, due to its low...
Superconducting electric motors offer the potential for low weight and high power in applications such as electric aircraft and high speed marine transport. Combined with renewably-sourced cryogenic fuels and advanced fuel cells they offer a path to zero-carbon mass transport. The proposed architectures of these extreme machines, operating at temperatures around 20K to 50K and employing very...
Electric propulsion is one way of making low emission flying possible. To do so, they must be particularly lightweight and have a high efficiency, at least as good as current systems such as gas turbines or turboprop engines. In order to reduce the impact of global transport on the environment and pollutant emissions, a revision of current systems is necessary and expedient. Because of its...
The aviation industry is responsible for a small but rapidly growing proportion of the world’s greenhouse gas emissions. One way to ameliorate this problem is by replacing hydrocarbon-based propulsion systems with electric propulsion systems. This approach requires storing energy in the form of batteries or liquid hydrogen. For large, commercial aircraft, batteries are currently untenable due...
