Although development of the line of gas turbine engines on the basis of a unified engine core is a widely used practice, the method of selection of the most efficient values of engine core parameters has virtually never been published.

The paper describes the method of optimization of values of engine core parameters jointly with optimization of values of every engine forming the line of engines developed on the basis of this core. Both stages of optimization are multi-objective and fulfilled using the results of simulation of engine as a subsystem of the airframe.
