Election of optimal methods for cleaning blades of closed monowheels of turbopump units obtained by the additive method of direct laser powder sintering

The creation of complex structural elements of aircraft using is promising and is widely used since such elements have several structural and technological advantages over the manufacture of parts using classical technologies. However, it requires the solution of several scientific and technical pro...

description The creation of complex structural elements of aircraft using is promising and is widely used since such elements have several structural and technological advantages over the manufacture of parts using classical technologies. However, it requires the solution of several scientific and technical problems to obtain products of high accuracy and roughness, the development of a technological process, the development of processing modes, and sometimes the development of a new design of products. For the development of technologies in modern rocketry, improving the quality and accuracy of the production of turbines of turbopump units, an important task is to search for new and improve existing technological solutions for the manufacture of such parts with high surface quality. The work aimed to analyze the existing processing methods for parts of turbopump units with complex geometry and select the most technologically advanced one for further use in technological processes. The objective of this article is an analytical review of existing methods of surface treatment of critical parts and the selection of the most technologically advanced method for finishing the blades of a closed-type turbine (with a shroud) to reduce the roughness and improve the quality of the working surface.
