The design and construction of a new experiment, to investigate the steady and unsteady heat transfer and aerodynamic behaviour of a rotating turbine in a transient facility, is described. The need for this experiment is discussed in the context of previous rotating bar wake and shock simulation work carried out in the Oxford transient cascade facility, and research elsewhere on the effects of rotating and three-dimensional flowfields on turbine aerodynamics and heat transfer. The outline concept and mode of operation of the turbine module are given before novel features of the design are presented in detail. Reference is made to a parallel paper also presented at this conference[18] which gives full details of the developments that have been necessary to allow the measurement of steady and unsteady heat transfer in this facility. Finally, the future work programme and possible plans for further facility improvements are given.
