United Engine Corporation has launched the manufacture of PD-8 engine blades capable of withstanding high loads. The parts are made at the innovative casting facility of UEC-Saturn in Rybinsk from advanced heat-resistance alloys created together with VIAM researchers.
A total of five new alloys have been developed in cooperation with National Research Center "Kurchatov Institute” – VIAM (Russian Research Institute of Aircraft Materials) to be used in a range of PD-8 engine components for SJ-100 regional jet, including highly loaded blades and vanes of low and high pressure turbines.
These alloys meet all world standards in terms of chemical stability, residual impurity level and mechanical properties.
“Any modern engine is primarily a result of scientific research and discoveries. The developed cast alloys helped implement advanced concepts incorporated by the designers in the power plant. Please note that new materials have been introduced in the blade workpiece manufacture without rearrangement of the production chain. In future, these alloys, that are capable of withstanding the required loads, may be used in new types of gas turbine engines,” pointed out Igor Ilyin, Chief Engineer of PJSC UEC-Saturn.
