Abstract: Turbocharger is an effective approach to satisfy the power performance and safety of Unmanned Aerial Vehicle during high altitude long endurance flight. According to simulation principle of engine operation, the simulation model of turbocharger and engine for onestage turbocharger engine has been initially established through applying GT-POWER, the validity of model was verified by experimental data. Furthermore, based on the specific requirement for power recovery of aero-engine in high altitude environment, the principle of engine and turbocharger at different attitude has been investigated, while the adjustable discipline of waste gate for turbocharger system was proposed. The results demonstrate that the simulation model is valid and the selection of turbocharger can meet requirements of safety design and matching.In the mean time,the model-based analysis can provide efficient evidence to improve turbocharged engine system performance under the circumstance of guaranteed system matching.
