Considering the geometric features of the air-cooled turbine bladesof the aircraft engines, the methods to sort the features in the parametric modeling of the blades were advanced. A parametric design system was developed with feature-based modeling technology. The development of the parametric module wasinstanced by the parametric design of a straight-back air-cooled turbine blade, which is the basis of the parameterization of the configuration accessory in the aircraft engines.
