To solve the resin blade precision control problem of low-speed research compressor of aeroengine, a reverse deformation optimization method is proposed. First, based on the reverse deformation theory, the optimization model is established. On this basis,the displacement field of resin blade is achieved through numerical simulation. Moreover, the mold cavity is optimized.Finally, a simulation sample application is presented for demonstration. And the result shows that the method can control the deformation of the resin blade and improve the manufacturing precision.
