In the paper the authors study the problem of turbine blades design. For computer-aided design in Mathcad the application program was developed as an element of the CAD system. A blade is shaped by three parabolas: back side– by one parabola, and pressure side – by two parabolas prescribing the maximum thickness of the profile. The program was tested on more than 30 profiles of blades for gas turbine engines.
