Research on Aero-Engine Performance Deterioration Model Based on the Cloud Particle Swarm Optimization

Compressor and turbine are the key components of aero-engine.Their performance deterioration has important effect on the engine performance.The component characteristic is corrected through the compressor and turbine revised factor.The performance deterioration model is established based on the revised component characteristics,and a new cloud particle swarm optimization is carried out in order to accelerate convergence.The effects of component performance deterioration are analyzed using the nonlinear performance deterioration model.The results offer theoretical referenced value to engine performance deterioration and relative influence between components.
