Computer-Aided Design of Gating Systems for Gas Turbine Engine Rotor Blades

摘要

The article describes use of an application package (AP) for designing gating systems. Possibilities of using the AP in casting rotor blades are examined. To determine the program's capabilities, a number of basic input parameters, as well as schemes of gating systems being designed and used and their geometrical and technological design parameters are given. The program was used to design a more efficient gating system than that is used in the production practice. Use of a designed gating system allowed improvement of productivity by 1.7 times and cost effectiveness of the production (metal recovery) by 27 percent. Basing on the results given in the article one can make conclusions about the possibility of effective AP use to modernize the process technology in the production practice.
