Optimization design of resonator tube for two-stroke piston aircraft engine

This study employs the one-dimensional flow simulation capabilities of GT-POWER software to develop a simulation model for an aviation two-stroke piston engine. The model is rigorously validated against experimental data, thereby ensuring a high degree of simulation accuracy. Subsequently, the resonant exhaust pipe of the engine is optimized using the Design of Experiments (DOE) method, with constraints imposed by the engine operating conditions and the spatial arrangement of the exhaust system. The optimization results indicate that the maximum power output of the engine is enhanced by 16.1% and fuel consumption is reduced by 14.2% under full-load operating conditions. These improvements highlight the significant potential of the optimized design for enhancing the performance of two-stroke piston engines in aviation applications.
