| Abstract: | Considering the geometric features of the air cooled turbine blades of 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 was instanced 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. |
