An application of numerical optimization to axial compressor design is illustrated in this paper. A design-point efficiency model is coupled to an optimization routine to create a method of deriving designs that are optimized for efficiency. Numerous constraints, many non-linear, are applied to control parameters to which the efficiency model is insensitive, such as rotor hub choking. The High Pressure Compressor of the Energy Efficient Engine that was designed for NASA by the General Electric Company is used as a vehicle to demonstrate the potential merits of the procedure; design-point efficiency increases of several points are projected for optimized designs.
