Hybrid Propulsion System Performance Modeling for Regional Turboprop Aircraft

This paper presents the development and validation of an aircraft performance model for regional turboprop aircraft, with a focus on integrating hybrid propulsion systems.Hybrid propulsion technologies, combining traditional gas turbines with hydrogen fuel cells, offer a promising solution to reduce aviation's carbon footprint, addressing the sector's impact to global CO2 emissions.The model, programmed in MATLAB, incorporates key flight phases (take-off, climb, cruise, descent, approach) and accounts for altitudedependent variations in air density, weight, and thrust requirements.Validation of the model was conducted using reference data from standard turboprop aircraft, demonstrating accurate fuel consumption and performance predictions across missions of 200 NM and 300 NM.The results confirm the model's reliability in supporting hybrid propulsion optimization while meeting mission operational requirements.
