Abstract

The generation of an overall propulsion system performance deck is key for the block fuel analysis of aircraft within an aircraft design workflow. In case of a hybrid electric propulsion system, it requires a sufficiently detailed modeling of the electric components and the turbo-machinery to generate such a deck. The values for the performance deck then result out of the steady-state solution of the drive train that needs to be found robustly despite non-linearities and dealing with novel limitations resulting from the electric machines. This paper describes how the author met this challenge by building a framework for the hybrid electric deck generation on top of a dedicated object-oriented modeling library for hybrid electric propulsion. A hybrid-electric single-aisle aircraft with an aft fan for boundary-layer ingestions thereby represents the prime application example.
