Conceptual Design Methods for Sizing and Performance of Hybrid-Electric Transport Aircraft

Abstract

The consideration of hybrid-electric propulsion systems disrupts the traditional methods for aircraft sizing and performance. Conceptual design methods for sizing, performance and identification of flight techniques for hybrid-electric transport aircraft are proposed in this thesis. The integrated performance and flight technique optimality of narrow-body hybrid-electric aircraft concepts are investigated to derive design heuristics, sizing axioms and to determine suitable market application.
