KNOWLEDGE-BASED CONCEPTUAL DESIGN METHODS FOR GEOMETRY AND MASS ESTIMATION OF RUBBER AERO ENGINES
J. Häßy¹, J. Schmeink¹; ¹DLR, Germany
A knowledge-based conceptual design method for estimating engine geometry and mass at part level based on thermodynamic cycle data and an advanced parameterization of turbo components utilizing splines is presented. The procedure is validated for a modern geared turbofan and the applicability in the context of MDAO is shown by means of an engine design study.
