Key performance indicators for turboelectric distributed propulsion

Purpose Recent advancements in electrified transportation have been necessitated by the need to reduce environmentally harmful emissions. Accordingly, several aviation organisations and governments have introduced stringent emission reduction targets for 2050. One of the most promising technologies proposed for achieving these targets is turboelectric distributed propulsion (TeDP). The objective of this study was to explore and identify key indicators for enhancing the applicability of TeDP in air transportation. Design/methodology/approach An enhancement valuation method was proposed to overcome the challenges associated with TeDP in terms of technological, economic and environmental impacts. The result indicators (RIs) were determined; the associated performance indicators (PIs) were analysed and the key RIs and PIs for TeDP were identified. Quantitative measurements were acquired from a simulated TeDP case study model to estimate the established key PIs. Findings It was determined that real-world TeDP efficiency could be enhanced by up to 8% by optimising the identified key PIs. Originality/value This study is the first to identify the key PIs of TeDP and to include a techno-economic environmental risk analysis (TERA) based on the identified key PIs. The findings could guide developers and researchers towards potential focus areas to realise the adoption of TeDP.

Automated summary

This study introduces an enhancement valuation method to overcome challenges associated with TeDP in terms of technological, economic, and environmental impacts. Key result indicators and performance indicators for TeDP were identified and analysed to determine potential improvements in real-world efficiency. This research is the first to conduct a techno-economic environmental risk analysis based on the identified key indicators, providing valuable guidance for developers and researchers in the adoption of TeDP.
