N2 - The goal of the presented work is an optimization of the tip seal with honeycomb land in order to reduce the leakage flow in the counter-rotating LP turbine of an open rotor aero engine. The goal was achieved in two ways: by means of the commercial software delivered by ANSYS with the Goal Driven Optimization tool and with the use of an in-house optimization code based on the evolutionary algorithm. A detailed study including mesh generation, computational domain simplification, geometry variants and a comparison of both methods is presented. The optimization methods give very similar optimal geometry configurations, where a significant mass flow rate reduction through the seal was obtained. Moreover, a sensitivity analysis and the results verification are presented.
