EVALUATION OF HYBRID ELECTRIC POWERTRAIN TOPOLOGIES AND THEIR INTEGRATION IN FUTURE AIRCRAFT CONCEPTS FOR GENERAL AVIATION

Kurzfassung

The presented paper introduces a methodology to evaluate novel powertrain topologies in early stages of the conceptual aircraft design. This methodology can be adapted to the requirements of an investigated aircraft concept. Specific criteria and weighting factors were derived from the requirements in preparation of the evaluation. The evaluation allows the identification of the most promising options for the powertrain topology. After the evaluation, a sensitivity study of the methodology was conducted, analysing the influence of the weighting factors on the final outcome. Furthermore, an integration concept of the selected powertrain topology for one aircraft concept is presented.
