This paper addresses the topic of multidisciplinary analysis (MDA) applied to hybrid electric aircraft (HEA) design focusing on the analysis of multi-fidelity models for hybrid electric powertrain design. The motivation behind this work is the retrofit of a turboprop aircraft with hybrid electric propulsion system. An adapted MDA for multi-fidelity conceptual aircraft design is set in place for the evaluation of the aircraft performance with a hybrid electric propulsion architecture. For the gas turbine system, high fidelity data have been used to develop multi-fidelity models with different levels of detail and complexity. These models have been integrated into the MDA to evaluate the performance of the vehicle for a given mission. Fuel consumption is the main metric used to assess the aircraft performance in the presence of uncertainty introduced on each propulsion model.
