Replication Data and Model for: Comparative Techno-Economic Assessment of Sustainable Propulsion Architectures for Regional Aircraft

Companion dataset and analytical model for a manuscript submitted to Aerospace Science and Technology (Special Issue: Sustainable and Green Aerospace Propulsion). This repository contains: (1) an Excel workbook (TEA_Regional_Aircraft.xlsx) implementing the complete Direct Operating Cost (DOC) and infrastructure cost model with editable input parameters for six propulsion architectures for a 72-seat regional aircraft — Conventional Kerosene, SAF Turboprop, Battery-Electric, H₂ Fuel Cell, H₂ Combustion, and Parallel Hybrid-Electric; (2) a Python script (TEA_MC.py) reproducing the Monte Carlo uncertainty analysis (10,000 iterations, triangular distributions); (3) the Supplementary Material (Tables S1–S4, Appendix A) with full DOC component equations and data tables; and (4) a README and requirements.txt documenting software dependencies and reproduction steps. All input parameters, distribution bounds, and model assumptions are documented in the Supplementary Material (Tables S1–S4). The reference mission is a 500 km flight at 80% load factor for an ATR 72-600 class aircraft under 2025 European baseline conditions.
