摘要

An opti mization process is used to redesign blades of a high-pressure compressor.An artificial neural network (ANN) method is coupled to Navier-Stokes solvers and is applied to three different redesigns.A newrotor blade of a transonic compressor is designed by modifying thick

stacking line andinlet angle using a 3Dapproach

with a significant efficiencyi mprovement at the design point.The off-design behavior of this new compressor is also checked afterwards

which shows that the whole performance of the inlet stage is improved over a wide range of mass flow.The losses are reduced

proving the good performance of the opti mum.The whole results indicate that the opti mization method can find i mproved design and can be integrated in a design procedure.
