This paper demonstrates the application of Kriging based approximations to the aerodynamic
shape optimisation of a transonic compressor rotor where multiple ?delities of analysis are
available. An extension to the co-Kriging method is implemented, and attention is paid to the
ef?cient construction of the approximate models. The initial data sample within each level of
the model is selected using space-?lling designs, and the covariance structure of the co-Kriging
models is obtained using a maximum likelihood estimation based on gradient optimisation with
adjoint functions. An ef?cient leave-one-out cross-validation method is used to estimate model
accuracy and is used to guide initial model re?nement.
