Abstract:
details of rocket-space technology of complex geometry for ideal work require roughness of the surface layer Ra = 0.09 - 0.31 µm , which is not achieved by the applied processing
methods and the requirements of the design documentation are not reached. The use of traditional
methods of finishing causes the unreliability of certain components and parts of rocket-space systems (RKS) are operating in extreme conditions. Abrasive-extrusion processing of parts provides
the conditions for design documentation on the surface roughness of parts of rocket and space technology. The best conditions for the treatment process were determined when using nitro lignin as working mixture, and an economic analysis was made of this treatment method compared with the methods used. The project demonstrates acceptable performance, net income and net present value are positive.
