C1.1 - Design methods for aircraft energy supply systems

Design methodology for aircraft energy supply system

A systematic methodological approach is proposed for the selection and dimensioning of an appropriate on-board energy supply concept for any given specific propulsion configurations. Its development comprises a detailed model-description of energy consumers and suppliers in the system. From these, physically-motivated reduced order models are derived. An adequate super-structure like framework is used to interlink the single components. To realise this model structure, a methological approach as well as a corresponding software toolbox is developed. Different optimization strategies are then applied to optimize system design as well as operating strategies.

As part of the energy system model, special attention needs to given to the electric and thermal subsystems of the propulsion system. These systems both gain in relevance by a large amount when considering electrified propulsion compared to conventional propulsion systems. For this reason, a strong link needs to be established to the groups of C4 and C5 for electric and thermal system design.

In cooperation with ICA-B, this project also aims to link the energy system design to the overall aircraft design. For this, design choices as well as requirements need to be coordinated with the aircraft design and the integration of the energy sytsem design into the aircraft design process is established. The interdependencies with other Projects within SE²A are also shown in the Figure below..
