ABSTRACT
This study presents a dual-platform simulation and validation framework for thermodynamic performance analysis of a micro gas turbine (MGT) intended for long-endurance unmanned aerial vehicle (UAV) applications. Using Gas Turbine Simulation Program (GSP) and Flownex, key performance metrics such as thrust, turbine inlet temperature (TIT), mass flow rate (MFR), and thrust-specific fuel consumption (TSFC) were evaluated across varying Mach numbers (0.1–0.6) and pressure ratios (1.3–1.5). Quantitative comparisons using root-mean-square error (RMSE) and percentage deviation reveal strong agreement between the two tools. This cross-validation provides confidence in simulation reliability and supports the design optimization of lightweight propulsion systems for UAVs operating at low to medium altitudes. © Akadémiai Kiadó Zrt 2025.
