About the job

The Department of Electric Power Engineering (IEL) at NTNU has a vacancy for a full-time 100% position as a Ph.D. candidate within the field of High Voltage Engineering and Electrical Machines and Drives – “Electric Insulation Systems in Superconductive Power Trains for Aircraft Propulsion”. The work of this project will be associated with NTNU's Clean Aviation initiative that is currently being embraced locally at NTNU. The prospective candidate will be part of a project team that works in close collaboration with the aircraft industry.

The main supervisor will be Associate Professor Pål Keim Olsen. Co-supervisor will be Professor Kaveh Niayesh.

The position reports to the Head of Department. The main workplace will be in Trondheim.

Duties of the position

The aviation sector is currently facing a paradigm shift. It has become clear in recent years that the key to the pursuit of zero-emission aviation is the integration of new disruptive hydrogen-based propulsion technologies into the aircraft architecture. Further still, concerns around the rapid scalability of hydrogen aircraft to regional flight routes have shown that revolutionary technology improvements are inevitably needed.

The achieved level of electrification will be essential, as it will be the key player to reduce non-carbon emissions (mainly from water, NOx, SOx, soot, contrails, and contrail cirrus), as well as reducing onboard fuel consumption and noise. In fact, the electrification component is projected to be increasing by a factor of 50 to 100, compared to today's solutions. However, to save additional mass due to the electrification, higher power densities will be required.

The introduction of cryogenically chilled superconducting materials can enhance the current carrying capability, meaning that one achieves low energy loss while enhancing the power density of the electrical components. This performance can be achieved by heat-exchanging the components with onboard liquid hydrogen (LH2) at cryogenic temperatures (-253 °C).

Electrical insulation systems at cryogenic temperatures have been recognized as one of the key challenges for the efficient, reliable, and practical development of superconducting power apparatus. The organic insulation materials in these systems deteriorate much faster than metallic and ceramic materials. Partial discharges, i.e. electron avalanches in gas at the surface or in the volume of the insulation materials, are both a cause and symptom of this deterioration. The main challenges for the insulation system design and validation in cryo-electric aviation are fast-switching power electronics voltage stress, low temperature, low pressure and cosmic irradiation. The PhD candidate will address these challenges in a state-of-the-art cryo-insulation material test bench to measure partial discharge characteristics and perform material lifetime validation. The test bench delivers switched pulses at 20 kV and 10 kHz, with ultra-high frequency partial discharge detection and control of temperature, irradiation and pressure in the test chamber. A further advantage of such a test bench is the opportunity to investigate partial discharges detection as a non-destructive method for condition monitoring of superconducting propulsors.
