The MOTOR project focuses on three main objectives related to the creation of novel CAE technologies, their seamless integration into existing industrial use-case design workflows, and the validation and exploitation of the modernized process chains.

The impact of new automatic design optimization technologies for industrial applications strongly depends on the ease of integrating them into existing process chains. To maximize the impact, MOTOR develops a modular toolbox of computational components to enable

  • Accurate unified geometry modeling of fluid energy machines
  • Domain-matching volumetric mesh generation and analysis-suitable parameterization for multi-domain geometries
  • Geometry-aware multi-physics simulations based on the isogeometric analysis approach
  • Geometry-aware design optimization loops that explore the full design space efficiently


Novel simulation-driven shape optimization methods will make it possible to design fluid energy machines in a much more automatized way than this is possible with conventional workflows. The aim of the MOTOR project is to get a 50% time reduction for four proof-of-concept demonstrators as compared to reference times for designing comparable prototypes using conventional state-of-the-art workflows used in daily production.


Novel simulation-driven shape optimization methods will enable the creation of fluid energy machines with increased efficiency. The aim of the MOTOR project is to design

  • Turning-Mid-Turbine-Frame for aircraft engines with a significant axial shortening while maintaining the overall pressure loss and the influx for the downstream Low-Pressure-Turbine
  • High-end ship propellers with low-noise requirement and increased cavitation inception speed
  • Kaplan or Francis water turbines with better efficiency over a wide range of operating conditions, increased unit flow rate through a turbine, and reduced cavitation
  • Screw machines with variable rotor pitch
