A framework for electrified propulsion architecture and operation analysis

Gokcin Cinar, Elena Garcia, Dimitri N. Mavris

The purpose of this paper was to create a generic and flexible framework for the exploration, evaluation and side-by-side comparison of novel propulsion architectures. The intent…

Methods to improve UAV performance using hybrid-electric architectures

Axel Yezeguelian, Askin T. Isikveren

When comparing and contrasting different types of fixed-wing military aircraft on the basis of an energetic efficiency figure-of-merit, unmanned aerial vehicles (UAVs) dedicated…

Energy management-based design of a Wankel hybrid-electric UAV

Teresa Donateo, Antonio Ficarella, Claudia Lucia De Pascalis

The purpose of this study is to investigate the optimization of design and energy management in a parallel hybrid-electric powertrain to replace the conventional engine of an…

Optimum sub-megawatt electric-hybrid power source selection

Benoit Picard, Mathieu Picard, Jean-Sébastien Plante, David Rancourt
