This paper presents a full-flight energy consumption modeling method for hybrid-electric commercial aircraft. A global optimization process based on this model is established to optimize fuel economy. This process enables the rapid determination of the optimal hybrid electric propulsion system (HEPS) configuration and its corresponding reference power output curve. The results for a single-aisle commercial aircraft indicate that the optimized HEPS can achieve fuel savings of 6.78%. This study provides a valuable reference for parameter design and energy management strategies for retrofitted aircraft.

摘要

This paper presents a full-flight energy consumption modeling method for hybrid-electric commercial aircraft. A global optimization process based on this model is established to optimize fuel economy. This process enables the rapid determination of the optimal hybrid electric propulsion system (HEPS) configuration and its corresponding reference power output curve. The results for a single-aisle commercial aircraft indicate that the optimized HEPS can achieve fuel savings of 6.78%. This study provides a valuable reference for parameter design and energy management strategies for retrofitted aircraft.
