The Institute of Flight Systems and Automatic Control (FSR) at TU Darmstadt has an ongoing research history in the field of predictive maintenance, also referred to as Prognostics and Health Management (PHM). With the aim of predicting a remaining useful lifetime (RUL) of an individual unit, this novel technique fosters new possibilities for cost savings (e.g. reduced downtimes) and maintenance optimization (e.g. spare part logistics). In parallel, it can be used to improve the overall system safety by monitoring the current health status of safety critical components.
In several projects, the FSR has worked on the development of (mainly) data-based diagnosis and prognosis algorithms as well as on concepts for the implementation and realization of condition-based maintenance (CBM) applications. By operating own test stands, the FSR is able to generate realistic degradation data, which is used to support the evaluation and benchmarking of the developed methods. In this context, the FSR is active in all six steps of the OSA-CBM process, reaching from the data acquisition and diagnosis to the prognosis and decision-making. With the use of cost-benefit analyses, also the economic view is accounted for..

Our current projects in this field include
DFG – Evaluation of the Technical Mission Risk of Unmanned Aerial Systems (2021-2024)
The evaluation of the technical mission risk of unmanned aerial systems is being progressed at the FSR funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation). The goal of the project is to aggregate all technical risks of an unmanned flight operation in a dynamic data-based estimation. For this purpose, suitable methods from the field of machine learning will be combined at both the component and system level. More…
smartHUMS (2020-2023)
The project smartHUMS is a joint research project funded by the Federal Ministry of Economics and Energy (BMWi) as part of the Aviation Research Programme (LuFo VI-1). The aim of the project is to develop a Health and Usage Monitoring System (HUMS) for monitoring and forecasting the technical condition of helicopter gearboxes and rotor blade e-actuators. The focus is on the coordinated integration of sensor technology and machine learning algorithms for remaining useful life (RUL) estimation. More…
RTAPHM (2019-2022)
The RTAPHM (“Real Time Analytics, Prognostics and Health Management”) project, a research project funded by the German Federal Ministry of Economics and Energy from the German Aeronautics Research Programme (LuFo V-3), is concerned with the development of a digital platform for automated service provision for Unmanned Aerial Vehicle (UAV) fleets. More..
INDI (2018-2021)
INDI (“Intelligent Data Utilization in Maintenance“) is a LuFo () funded joint research project with project partner Lufthansa Technik. Within this project, the FSR assesses the development of intelligent algorithms and data analysis strategies in the field of machine learning and artificial intelligence in order to optimize the maintenance of aircrafts. Aviation research program of the Federal Ministry of Economics and Energy More …
SiFliegeR (2016-2019)
With the SiFliegeR project the FSR investigates how PHM can be leveraged to generate a dynamic and system specific safety analysis, based on the current system health status. The applicability of this method is demonstrated on an unmanned aerial vehicle’s control surface actuation system. More…
MAAM (2016-2018)
MAAM (Mission-based Availability Assessment for Multirotor UAVs) is a third party funded project with the aim to increase the safety of autonomous multirotor UAVs through modern PHM algorithms and intelligent monitoring systems. More …
