The paper presents the results of calculating the strength properties for the fan blades of a regional aircraft gas turbine engine under consideration of manufacturing deviations. The models of blades with different geometric deviations on the airfoil being analyzed, the design model of the fan assembly, the strength properties being estimated, and the design scheme for a set of blades are described. An example of the calculation results is given.
