Abstract
The article analyzes the problems arising during the repair of gas turbine engines. Based on the analysis of problems, a gas turbine engines rotor repair scheme is proposed using virtual assembly technology. The proposed scheme will allow to reduce the cost and to increase the efficiency of repair work. Example of gas turbine rotor repair using virtual assembly technology is considered. The results of predicting the dimensional accuracy of assembly parameters based on the simulation of parts with real geometry are presented.
