title: Reverse engineering and numerical modeling of the viscous gas flow of the centrifugal compressor stage of the TS-21 turbo starter to construct a pressure characteristic for the purpose of further modernization
abstract: n the research, reverse engineering of the centrifugal compressor stage of the TS-21 auxiliary power unit is carried out. The calculation is also modeled in the finite element method program taking into account all recommendations using computational gas dynamics methods. As a result, the compressor pressure characteristics are built for its further modernization. An assessment of reverse engineering for industrial tasks in modern realities is also carried out. Some shortcomings of 3D-scanning f
