Hybrid-electric propulsion has been investigated as a concept that could address this problem by potentially bring fuel-saving and emissions reduction. This research assesses whether an electrically assisted regional turboprop aircraft could reduce exhaust emission gases in the LTO cycle. A mission analysis routine was developed to estimate the aircraft's performance throughout a 1000 Km mission. Moreover, it was built a turboprop engine model that computes accurate engine performance and a simplified electrical system model to estimate its weight with the power requirements. The degree of hybridization (percentage of electric power provided) was varied from 10 to 100 % and the battery specific energy from 300 to 1000 Wh/kg in the simulations. The performance and emissions of an ATR72-600 were compared to the electrically assisted versions, and the impacts of hybridization were outlined.
