    Abstract
  • Impingement pipe is the core component of the impingement cooling in turbine blade. In order to realize the rapid modeling of impingement pipe in turbine blade with complex cooling structure, a generative rapid modeling method was proposed.Firstly, the body of pipe was created by section curves which suits the shape of channel in blade and generated by curves created by insect-shape method. Then by using envelope surface trimming method and along-curve array method, the modeling stability and efficiency of cooling hole and hump are guaranteed.And the fitting precision between impingement pipe and blade is guaranteed by an iterative formula about protrude position.Finally, a rapid impingement pipe modeling program was developed based on UG Open API, and the modeling result validated the feasibility of the proposed method.
