In the joint project STELAR, a general aviation aircraft is being optimized and adapted to the requirements of an electric propulsion system. The project is based on the findings from previous research projects on flight strategies, the development of safety-critical software in small teams and new powertrain concepts. The project of the Technische Universität Berlin is helping to make a contribution to more environmentally friendly aviation within the joint project STELAR.
TU Berlin develops a guidance function that incorporates the current status of the drive components and the atmospheric conditions into the trajectory planning. This leads to a reduction in emissions and an increase in range, which is essential for electric aircraft. The function is validated in flight simulator tests and hardware-in-the-loop tests. Basis for these developments is a model-based approach. A modular simulation environment has been created on the basis of models of aerodynamics and the propulsion system. An energy-optimized and therefore resource-conserving trajectory control system for the general aviation is being developed using this simulation environment.
As part of the project STELAR, the Institute of Aeronautics and Astronautics at the Technical University of Berlin is making a contribution to more environmentally friendly aviation.
The TUB is currently working on the STELAR function. The following publications have been produced for this purpose:
