Original pylon architecture design using 3D HPC topology optimization

Abstract : In the context of fuel consumption reduction, integrated power-plant system optimization plays a central role in the definition of on-wing engine performance. The fuel consumption is affected, among other, by specific engine deformations, called tip clearances. This study con- cerns the optimization of the engine-pylon attachment structure with respect to the tip clear- ances (and thus the fuel consumption). A hyper-static concept for engine to aircraft attach- ment structure is considered for the design zone and optimized within a topology optimization framework. A simple engine model is integrated to a 3D design zone model through static con- densation. Stress based constraints as well as the fuel consumption based objective function are implemented within the proposed topology optimization framework. In order to achieve realistic designs, high density for the mesh of the design zone is needed. Accordingly a parallel implementation within an HPC framework was considered. First results in this direction are presented.
