    Abstract
  • Trailing edge slots are important cooling structures in turbine blade. In order to realize the precise modeling of these structures in bowed-twisted turbine blade and improve the modeling efficiency, a rapid generative modeling method was proposed, including the tool body creation step and the slot windows creation step. Firstly, the tool body with the same or similar bowed-twisted condition as the blade was created via the matching algorithm of inside and outside blade profiles and the direction determining algorithm of pressure and suction sides. Then the groups of slot windows with different sizes were created by employing specific data structure to store the window groups information. Finally, a rapid trailing edge slots modeling program was de-veloped based on UG Open API, and the modeling result validates the feasibility of the method.
