Aero-engines involve numerous design variables that strongly influence mission block fuel, climate impact and costs. Evaluating many engine designs at overall aircraft level using detailed design workflows is computationally expensive. This paper proposes a more efficient sub-level engine optimization strategy based on sensitivities to efficiently solve engine optimization problems.
