Research on Parameterized Aerodynamic Optimization Design of Fan Blade
Based on a fan blade,a parameterized model of the blade was established and a multi-disciplinary optimization de-sign platform was built.Single-objective optimization was carried out with the air volume and torque of the fan as the goals.The optimized design variables are the airfoil installation angle,airfoil chord length,blade camber and blade stacking line camber and sweep.The particle swarm optimization algorithm is used to optimize,and the optimal fan blade configuration under differ-ent indicators is obtained.The design weight and influence law of the key design parameters of the fan blade are determined.The airfoil installation angle and chord length have the greatest influence on air volume and torque.As the airfoil installation angle and chord length increase,the air volume increases and the torque also increases.
