Today, technically complex systems, whether in aviation, aerospace, energy, or transport, are equipped with a large number of different sensors to ensure functionality and operational safety. Common to all systems is the effort to drastically reduce environmental emissions and increase operational safety and automation. The combination of sensors with data-based models, with the goal of "sensor data consistency", is considered crucial for the safe and efficient operation of technically complex systems.
In the SAFER² impulse project, scientists from a total of 12 institutes are therefore bringing together the expertise available at DLR from the fields of sensor technology, actuator technology, machine learning, and artificial intelligence in a cross-focus manner. By linking sensor data with system information from machine learning models, they want to establish a veritable "nervous system" of a complex technical system in the project. This nervous system is to monitor and recognize deviations, such as weather influences, sensor failures, structural damage, noise emissions, etc., and react to them at an early stage. In a total of five demonstrator tests, the project participants want to bundle and further develop their skills from the fields of aviation, energy, and transport. From the beginning, the focus will also be on the system’s certifiability.
The Institute of Aerodynamics and Flow Technology is leading the project and is responsible for the demonstrator "wind energy blade", as well as for the further development and integration of the MEMS measurement technology for aerodynamic and aeroacoustic measurements. In addition, the scientists prepare the model hardware for wind tunnel tests and deal with the further development and application of machine learning models for real-time prediction of complex systems based on sensor data.
