Details

This project is in collaboration with Rolls-Royce, and will carried out within the Department of Mechanical Engineering at the University of Sheffield

In aero-engine design, ensuring gas flow does not leak around the periphery of the compressor is an essential requirement for efficient performance, and low specific fuel consumption. This is achieved by ensuring clearances between the rotating blades and surrounding casing are minimised. Abradable linings are also used on the inside of the casing, to provide a soft material for the blades to incur into, should the blades come into contact with it as the engine flexes during flight.

However, even with the use of abradable linings, compressor blades are still prone to wear resulting in gas flow leakage. The aim of this studentship is to investigate the use of engineered foams as an alternative abradable lining material, with the target of demonstrating an improvement in cutting performance over traditional solutions. The foams will be developed with specific material properties ensuring that they are cut efficiently by the blade tip, reducing the possibility of blade wear and damage.

Testing will be undertaken on a novel high-speed test platform for abradable linings at the University. Project work be focused on understanding the cutting performance of a range of different abrasive tipping materials available, along with some contact modelling in order to further understand the mechanics of the system. This studentship is closely aligned to a range of on-going Rolls-Royce development programmes leading to a close working relationship, and will involve a series of short placements within Rolls-Royce.
