摘要：
This paper demonstrates how, by means of Reduced Order Modelling (ROM), CFD cost can be drastically reduced and, in addition, a more complete investigation of a continuous design space obtained by adding experimental fluid dynamics (EFD) and flight fluid dynamics (FFD) data. The 'Gappy' Proper Orthogonal Decomposition (GPOD) method is used to enrich the EFD and FFD data to the size of their companion CFD. All three are then combined in a multidimensional database providing a much finer real-time exploration of a design space. Examples from aerodynamics and in-flight icing are given.
