Number_reference_aid_programme: SA.41471(2015/X) Purpose of public aid: Article 25 of Regulation (EC) No 651/2014 of 17 June 2014 declaring certain categories of aid compatible with the internal market in the application of Articles 107 and 108 of the Treaty That’s it. EU L 187/1 of 26.06.2014). The qualitative competitiveness of high-pressure turbine blades with a dendritic — column structure is determined by very high requirements in terms of precision of castings, repetitive chemical composition of alloys, permissible content of gases and undesirable elements, metallurgical purity of alloys, permissible foundry defects, surface quality, reproduction of complex cooling channels, structure of alloys in cast and heat treatment, as well as mechanical properties of superalloy and durability of products. Precise castings of blades with dendritic structure — column structure are made only by a few foundries in the world, and the technology of their production is strictly protected. The project will produce blade castings using directional crystallisation with column grains, parallel to the direction of crystallisation <001 >. This will increase the quality competitiveness of products produced in the CPP foundry. The aim of the project is to improve individual processes of production of complex geometrically complex and meet the strict operational requirements of critical precision castings of nickel superalloys with dendritic structure — column by carrying out the works described in the project, and then on their basis, development and implementation (after the end of the project) into the manufacturing practice of the production technology, a new precision casting of the high pressure turbine rotor blade from nickel superalloys with internal cooling channels, intended for operation in harsh operating conditions. Internal channels will be mapped with comb ceramic cores
