Summary

Research at the Department of Engineering Science has produced an innovative method for measuring the capacity of jet engine turbines, resulting in a reduction in engine development times and savings of over £6m for Rolls-Royce between 2008 and 2013. Since this method eradicates the need to run a test facility continuously, the technique is superior for making capacity measurements in respects of cost, turnaround time and accuracy.

As a result of this breakthrough, Rolls-Royce ceased in-house turbine testing in 2008, instead using the Oxford Capacity Facility. This has helped Rolls-Royce to accelerate development of its Trent family of engines, enabling the company to deliver a new generation of cleaner, cheaper-to-run engines at much lower cost.
