The Rostec State Corporation is increasing the production of high-tech parts for gas turbine aircraft engines. Power plant blades are among the most knowledge-intensive and difficult components to manufacture, the press service said.
Only about 5% of countries possess the technology to create them, and Russia is among them. The parts have a complex external geometry, and the cooled turbine blades have an equally complex geometry of internal cavities and channels designed for cooling.
During engine operation, the temperature of the gases rotating the turbine can rise to 2000 degrees Celsius.
This is higher than the melting point of the metal from which the turbine blades are made. Only a set of measures – the use of high-tech heat-resistant alloys, the use of a cooling system, and the application of a heat-protective coating – allows such blades to work in extreme conditions, maintaining integrity throughout the entire established service life.
Specialists produce several hundred types of compressor and turbine blades for engines. Today, the pace and volume of production of these parts for power plants that equip domestic aircraft and helicopters are growing.
One engine can have more than 3,000 different blades, from miniature compressor blades about 20 mm high to engine fan blades a meter or more high. For example, the height of the working blade of the PD-35 engine fan is 1.3 meters.
Earlier www1.ru reported that a unified maintenance system for Baikal, Osvey, and Ladoga aircraft will appear in Russia.
