Abstract: The development status of the composite blade general strip theory and airfoil numerical simulation method is briefly described. A method of two-dimensional flow field analysis is used to deal with the different states of a typical airfoil section, so the stress nephogram and velocity nephogram in different states are obtained. According to the stress condition and gas velocity distribution in various states, the applicable area and basic requirements of the principle of aerodynamic rehabilitation are discussed and derived. The repair principle and prospect of composite blade are prospected.

Key words: blade design, numerical simulation, repair principle
