“…For this purpose, the procedure of geometry extension within the dimensions meeting the conditions of the part mounting into the assembly, and simplification of the initial topology of the item to be designed are performed [1]. Static loading diagrams and loads variation rates are defined based on the operation force diagrams in different flight modes.…”

Abstract. This paper addresses a new approach to aircraft engine parts designing using the topological optimization algorithm for production by additive manufacturing. The full mathematical formulation which includes the problem statement within the elasticity theory and the SIMP optimization procedure is presented. The criterion particularities for evaluation of strength properties of the gas turbine engines parts according to the Aviation Regulations are specified. Optimization of the typical hinge bracket topology is performed, and the stress state of the part with the initial geometry and the optimized geometry is evaluated.

The paper studies the matters of numeric simulation of the processes of casting, crystallizing and cooling down to room temperature, and addresses the related problem of the stress-strain state of the casting process in manufacturing the cast parts of a gas turbine engine. 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.

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.
