Deformations and casting defects depending on the gating system for gas turbine engine castings

Abstract

The article covers researching the processes of pouring, crystallizing and cooling to room temperature, while simultaneously solving the related task of the stress-strain behaviour of the casting process in course of the heat-protective panels manufacture. The influence of the technological parameters of casting onto the development of the deformation defects was evaluated. The works were performed on incorporating predeformation into the burn-out model for compensating temperature deformations during casting, and on production and control of the above casting with predeformation.
