Bladed discs are one of the most critical and heavily loaded components of gas-turbine engines. Increasing requirements for efficiency, reliability and environmental friendliness of gas-turbine engines demand from the industry development of new designs and, hence, the effective methods for numerical analysis of bladed discs which can enable such a development are needed.
This project is aimed at development of numerical methods for the effective analysis of sensitivity of bladed discs to variation of some design parameters for specified characteristics. Moreover, the sensitivity-based methods allowing fast assessment of effects of variability and uncertainty of material properties and geometry of blades on the static deformation and vibration amplitudes of bladed discs will be developed.
Realistic large-scale finite element models will be used for bladed discs and the nonlinear interaction forces at blade-disc and shroud friction contact interfaces and anisotropy of material properties will be allowed for. Two major types of deformation will be considered: (i) static and (ii) dynamic. The sensitivity and statistic characteristics will be analysed for a number of characteristics for structural deformation, including: stresses, strains, natural frequencies, mode shapes and vibration amplitudes.
The PhD study will be performed in a close cooperation with an industrial customer within a research project fully-funded by one of the leading European gas-turbine engine company.

One PhD scholarship is available for a suitable candidate from UK, EU, or North America with a strong interest in structural dynamics and numerical analysis. The scholarship is for 3 years and offers a stipend (£14,296 per annum for 2016-17), tuition fees (at the current UK/EU rate) and a research support grant. Depending on the needs of the project the scholarship may be extended up to 6 months to implement the results of the projects on the company premises in Europe. Candidates with strong capacity in numerical modelling, finite element analysis, mathematics and programming are particularly welcome to apply.
