The project is directly concerned with safety & reliability of aero engines, addressing the problem of High Cycle Fatigue of turbine blading & the measures needed to avoid it. On average 2.5 HCF incidents occur for each new engine design despite use of the best available tools today, and compromising the efficiency of the design to reduce risk. The objective of the project is to target a 50% reduction in such incidents by gaining a deeper understanding of the complex aero elastic phenomena involved. This will be achieved by performing a series of experiments. One set will provide data about one of the more complex, least understood forcing functions, Low Engine Order and the other focuses on the prediction of blade response including sources of scatter causing the mistune phenomenon. The data obtained (measured unsteady pressures & individual blade responses) will be used to validate & improve the partner's aero elastic codes, used for prediction of this multidisciplinary problem that depends on knowledge of both aerodynamic & mechanical behaviour.
