Objective Research objectives and content This proposal deals with the vibration analysis of turbomachinery rotor blades which are subjected to time-varying aerodynamic forces produced by the gas flow past the stator blades, the industrial term for the phenomenon beingforced response. State-of-the-art analysis and design tools for estimating such aeroelastic behaviour are deficient in terms of predicting blade response levels quantitatively and hence blade fatigue life cannot be assessed to a required degree of accuracy. It is therefore proposed to develop a numerical predictive model with the following features: (i) accurate modelling of the unsteady flow including wake behaviour and gust response, (ii) structural model including non-linear friction damping, (iii) flexible rotor blades and their effect on the flow, and (iv) adequate representation of blade cooling. Training content (objective, benefit and expected impact) The objective of the project is to acquire a deeper knowledge and a wider competence in the field of fluid-structure interaction in a turbomachinery environment. This is multidisciplinary topic in which the applicant has a good basic knowledge and for this reason the benefit and the expected impact can only be positive. Links with industry / industrial relevance (22) The work will take place at the Centre of Vibration at Imperial College which is a Centre of Excellence in these studies. The Centre has very close links with Rolls-Royce plc which will contribute to the project by making available in-house expertise as well as measured data.
