The latest episode of the ORF science programme “Mayrs Magazin” focused on how air travel can become more climate-friendly in the future. The programme also showcased technologies developed by the AIT Austrian Institute of Technology that are designed to contribute to more sustainable aviation.
Air traffic currently accounts for around three per cent of global greenhouse gas emissions – and the trend is rising. To reduce energy consumption and emissions, a combination of new propulsion systems, innovative materials and sustainable fuels is required.
In the feature, AIT aviation expert Michele De Gennaro explains the role batteries could play in aircraft in the future. They can, for example, supply energy to on-board systems and reduce the load on the engines – an important building block on the path to more efficient aircraft.
Another focus is on structural batteries, where energy storage is integrated directly into the aircraft structure, such as in the wings. At AIT, corresponding solutions are being developed, which are currently being tested in the European MATISSE project. In the feature, AIT expert Helmut Kühnelt explains the challenges involved in developing such systems, particularly with regard to safety and non-flammable materials.
Icing of aircraft components is also a key issue. AIT aerodynamics researcher James Page is working on analysing airflow patterns to make aircraft structures less susceptible to icing in future – which could reduce energy and material costs.
