Application of Probabilistic Set-Based Design Exploration on the Energy Management of a Hybrid-Electric Aircraft

The energy management strategy of a hybrid-electric aircraft is coupled with the design propulsion system itself. A new space exploration methodology based on Set-Based Design introduced to analyse effects different strategies fuel consumption, NOx and take-off mass. Probabilities are used evaluate discard areas not capable satisfying constraints requirements, saving computational time corresponding an average 75%. study carried 50-seater regional turboprop parallel architecture. modelled as piecewise linear functions degree hybridisation applied mission phases explore how complexity number hybridised segments can influence behaviour system. results indicate that parametrisation does affect trade-off between consumption emissions. On contrary, significant identified which hybridised. That is, least obtained only by hybridising longest phase, while less emissions generated if more Finally, maximum mass was investigated parameter, impact objectives analysed. Three were suggested from these findings, achieved reduction up 10% 15%.
