TY - CHAP A1 - Hendler, Marco A1 - Bestle, Dieter A1 - Flassig, Peter Michael T1 - Cloning Strategy for Aerodynamic Compressor Design based on Throughflow Analysis T2 - Proceedings of Montreal 2018, Global Power and Propulsion Forum, 7-9.05.2018 N2 - Due to their high complexity, aero engine development is a time-consuming and cost-intensive process. Therefore, pre-developed proven aerodynamic and geometric compressor information is often used as starting point and transferred to new compressor designs. In the present paper, a new approach for aerodynamic cloning of an already existing compressor flow to a new compressor geometry by use of a streamline curvature based Throughflow solver is presented. Parameterized compressor quantities are automatically modified with the help of optimization strategies, and the resulting compressor aerodynamics are compared to a reference design in each iteration step. The target is to minimize the discrepancy between reference design and new design regarding essential flow parameters like de Haller number, Mach number etc., and thereby to reproduce the aerodynamic image of the reference design. Thus, already collected experience from existing compressor flow fields can be used to reduce costs for developing as well as testing of new compressor configurations. Conducted investigations show a notable acceleration of the design process in comparison to former strategies starting from scratch while achieving an acceptable compliance of aerodynamic parameters.

An optimization with the AAO (All-At-Once) approach is performed as a baseline and compared against the performance and results of three cascaded optimization strategies: CO (Collaborative Optimization), BLISS 2000 (Bi-Level Integrated System Synthesis) and ISOC (Interface Segmentation Optimization Concept). The optimization problem is based on a thermodynamic core engine model representing an industrial application example. The results are assessed with respect to typical requirements for multidisciplinary core engine design. The impact of the used optimization strategy on the performance of the optimization concept is investigated and discussed.
