Research on Performance Optimization of Fuel Supply System for Aviation Piston Engines in High Altitude Environments

The high-altitude environment features low air pressure and thin air, which significantly affects the performance of the fuel supply system of aviation piston engines. This paper conducts an in-depth study on the influence mechanism of the high-altitude environment on the performance of the fuel supply system of aviation piston engines. Through theoretical analysis and data statistics, targeted optimization measures are proposed, and the effectiveness of the optimization scheme is verified through simulation experiments, aiming to improve the reliability and economy of the engine in high-altitude environments.
