Gas Turbine Engine Off-Design Calculations Using Matlab
Keywords:

It is a common practise not only in turbomachinery to use lookup tables in engine models to describe some characteristics. These characteristics are often available in graphical form of a diagram with multiple plots which were formerly used in calculations for manual reading. Using an example of centrifugal compressor map calculation, this paper shows how a diagram with multiple plots can be transformed into a lookup table that is used in automatic calculation.
