JSC “ODK” experience in implementing digital twin technologies in the design of gas turbine engines

The prerequisites for the formation, basic principles and approaches of the GTE design technology used in JSC “UEC” based on the concept of “digital twin” are considered. The components of the DT technology are fixed, three types of computer models included in the perimeter of the digital twin: models “as designed”, “as manufactured”, “as tested”, are considered. The necessity for constructing automated computational chains is noted and a brief description of the process is given.
