The modern design process is based on multi-criteria optimization methods. They require at the initial stage collecting a maximum amount of reliable information. In the case of centrifugal compressor would be desirable to obtain specified performance maps in the form of a digital array. High-resolution arrays are suitable to interpolate values between their nodes. Access to digital resources is often limited, because they are an intellectual property of the certain companies. As a temporary replacement is possible, the use of the characteristics published as illustrative or design characteristics published from solutions of the previous generations. Presented article takes the issue of adapting simplified compressor characteristics to the requirements of PMDO (preliminary multidisciplinary optimization) process. Selected characteristics due to the low density of the contour lines on the map field was not suitable for direct conversion into digital form Presented map was reconstructed by the method of approximation using a polynomials of nth degree. Reverse engineered map generates correct values at compressor contour map nodes. Chosen method is characterized by low demands in terms of computational power requirements, which makes it suitable to use also in embedded microprocessor control systems. Main advantage of presented method is allowed to create a working replacement of digital map that can be used until time when inputs will be complemented by experimental data.
