This paper considers the optimized analytic algorithm of constructing the mathematical model for determining the crosssection area of the aircraft gas turbine engine (GTE) air inlet (AI) channel surfaces with hyperbolic-elliptical shape contours with the first order smoothness. The resulting model advantage is the possibility to calculate the hyperbolic-elliptical shape contour areas and obtain their images on computer according to pre-specified dimension. Developed model accelerates solution of optimal selection of the AI contour geometrical dimension and its shape control.
