Purpose The purpose of this paper is to present the advantages computer-aided design/rapid prototyping (CAD/RP) usage in designing and manufacturing core models used for precise casting with direct single solidification aircraft engine turbine blade cores.
Superalloys have been developed for specific, dedicated properties and applications. One of the main application this material is advanced, high-performance aircraft engines elements. Turbine engine creates harsh environments materials due to high operating temperature stress level. Hence, as described in article, many alloys used turbine section these are very complex highly optimized. This article provides an overview structural changes that occur during aging process wrought cast insight...
Purpose The purpose of this paper is to present coordinate measuring system possibilities in the meaning geometric accuracy assessment hot zone elements aircraft engines. aim prove that method, which uses blue light and most sufficient cost-saving can be used production line for serial manufacturing elements, a high level required.
Abstract A study of the crystal orientation and structural perfection single blades obtained by Bridgeman method from CMSX‐4 nickel superalloy at various withdrawal rates between 1 5 mm/min was carried out using Laue diffraction X‐ray topography methods as well electron scanning microscopy. Blades consisted mainly regular γ' phase, with [001] ‐type direction close to blade axis. The angle deviation in relation axis changes locking piece end. dependence this on distance has been named...
