Safe and reliable electrical and thermal networks for hybrid-electric propulsion systems (ETHAN).

Climate-friendly aviation must be safe and competitive. For this, the design and management of electrified flight propulsion systems must be developed holistically and systematically. The aim of the project is a coupled consideration of electrical and thermal systems for hybrid-electric flying. The aim of the project is to develop methods for the systematic optimization, control and testing of highly integrated electro-thermal overall systems for hybrid-electric aircraft. An optimization as well as a weight reduction of the systems shall be achieved. All aerospace-specific requirements must be met in the process.

The project is a joint project. The following companies and institutions are involved:

Rolls-Royce Germany, Brandenburg University of Technology Cottbus-Senftenberg, Karlsruhe Institute of Technology, Technical University of Munich, Leibniz University of Hannover, Technical University of Darmstadt, Technical University of Braunschweig (IEMV, elenia, IMAB).

The following work packages are developed by BTU Cottbus-Senftenberg and chesco:

Thermal network modeling and optimization (Prof. Höschler)

  • Model library of thermal network components
  • Model verification with the help of measured data
  • Optimal system design
  • Consideration of new coolers for weight reduction and efficiency increase

Electro-thermal network control (Prof. Schiffer)

  • Predictive energy management system for overall thermo-electric system
  • Intelligent power control system for electrical network components
  • Real-time fault detection system for drive components

Integrity testing of the electrical system (Prof. Möhlenkamp)

  • Systematic test of electrical drive components and systems
  • Construction of a test environment specially tailored to new types of battery-electric drives
  • Systematic acquisition of test requirements incl. documentation and evaluation

This project is funded by the Federal Aviation Research Program.
