Master Thesis (m/f/d) Long-Range Transport Pre-Design Utilising PEM Fuel Cells for Propulsion and Power Generation

Join to apply for the Master Thesis (m/f/d) Long-Range Transport Pre-Design Utilising PEM Fuel Cells for Propulsion and Power Generation role at AES Aerospace Embedded Solutions GmbH

Masters thesis at AES GmbH (Munich) in cooperation with SAFRAN Tech (Paris)

Motivation

Regarding hydrogen (H2) combustion, preliminary studies conducted on a wide range of markets indicated the Middle-of-Market (MoM) and Long-Range (LR) segments show improved vehicular efficiency and lower aircraft design weights penalties compared to other market segments. There exists much interest in examining the feasibility of Propulsion and Power Systems (PPS) comprising Polymer Electrolyte Membrane Fuel Cells (PEMFC) based upon H2 as the energy carrier. Apart from the potential of significantly improving the overall propulsion system efficiency, provided the architectural layout is approached thoughtfully there also exists scope to remove the dedicated standalone auxiliary power unit.

Objective and Approach

This work shall be undertaken by a researcher supervised by SAFRAN Tech (Paris, France) on-site at AES GmbH (Munich, Germany). The scope of work is presented below with overall aim of comparing and contrasting the relative merits of LR commercial transport concepts utilising PEMFC, and, blended JET-A1 and Sustainable Aviation Fuel (SAF) as chemical fuel. A breakdown of the research activity is proposed as follows:

- Reference Aircraft, Top-Level Aircraft Requirements and Technology Insertion Strategy

• Declaration of Top-level Aircraft Requirements and State-of-the-Art Reference LR Aircraft Modelling
• Airframe / Propulsion and Power Generation / Non-propulsive Systems technology insertion strategy
• Pre-design sizing of projected conventional technology LR transport aircraft assuming blended JET-A1+SAF

- Long-Range Transport Concept with Integrated PEMFC Propulsion and Power System

• Pre-design sizing LR transport aircraft with integrated PEMFC PPS
• A detailed investigation of aircraft-side only considerations and challenges associated with ground as well as en route operational scenarios

- Evaluation and Benchmarking

• For H2 versus projected blended JET-A1+SAF based LR transport aircraft a sufficiently detailed array of stack-up charts highlighting differences and associated explanations for each technical domain constituting multi-disciplinary integration and sizing
• Cash and Direct Operating Cost analysis that compares and contrasts PEMFC approach to that of blended JET-A1+SAF
