Noise reduction has now become one of the crucial issues in aeroengine design. In modern systems much of the noise is generated by the fan, particularly by the interaction between the fan-blade wakes and downstream vanes, as well as by rotor-stator interactions in the compressor. At present, however, methods for predicting the noise resulting from these interactions, and the passage of this noise through other blade rows, are of limited scope. In this proposal we aim to rectify this situation by developing new, analytically-based prediction methods, which will model all the important features of the interactions and which will therefore represent a considerable improvement over the methods currently available. In particular, we will be especially concerned to extend the state-of-the-art by: modelling three-dimensional effects, including blade sweep, radial phasing of the unsteady fields and the action of the blade tips; by including swirl behind the fan; by including the effects of blade camber and thickness; and by studying the noise generation in transonic flow. The aims of the proposal are to develop new prediction methods which account for these features, and which can be incorporated into existing prediction methodologies, to validate these methods by comparison with data, and to exploit the analytically-based nature of the models to provide important scaling information to be used at the early stages of design.
