The validity of such theoretical or empirical prediction models can only be established if researchers apply their flutter and forced vibration predictions to a number of well documented experimental test cases. In the present report, the geometrical and time-averaged flow conditions of nine two-dimensional or quasi three-dimensional experimental standard configurations for aeroelasticity in turbomachine cascades are given. For each configuration some aeroelastic test cases are defined, comprising different incidence angles, Mach numbers, interblade phase angle, reduced frequencies, etc. Furthermore a proposal for unified nomenclature and reporting formats is included, in order to facilitate the comparison between the different experimental data and the theoretical results.
