English abstract:
Digitalisation offers optimised aircraft operation, enabling, for example, more efficient airspace use, maintenance and crew support. Connected aircraft and wireless network infrastructure solutions are required to turn aircraft into an internet-of-things-type device. Many efforts have been done in recent years to improve hardware and software for wireless networks and sensor/actuator nodes, such as energy-aware protocols and ultra-low power electronics. However, the power supply currently relies either on high cabling efforts or high maintenance efforts in case of batteries. A key enabling approach to overcoming these drawbacks is energy harvesting. Aircraft offer unique temperature variations during operation due to high temperature differences and gradients, when flight phases change. An extremely promising thermoelectric harvesting solution is the use of phase change materials, in order to exploit the latent heat. In addition to the temperature gradient induced heat flow between the aircraft and the outside environment, the latent heat of the phase change material, e.g., water, contributes significantly to the resulting energy budget. Several dynamic thermoelectric energy harvester designs have been realised and tested in the lab. A seven-month test flight campaign has successfully demonstrated the capability of the dynamic thermoelectric energy harvester as reliable power source.
