A Three-shaft Resource for Investigation of Engineering Phenomena in High Performance Transmission Systems Facility

The next generation of aero-engines will need to meet more stringent environmental targets than today’s engines; they will need to be more cost effective to operate in order to meet airline customer demands; and they will also need to be more reliable to meet our expectations as the travelling public.

In order to achieve these targets, the next generation of aero-engines will have to run hotter, at higher shaft speeds, and the core of the engine which contains the bearing chambers will need to become smaller. It is already a very difficult task to design bearing chambers and internal gear boxes so that the oil can reach all of the components it needs to lubricate, and so that the oil collects as much of the heat from inside the chamber as possible without the oil getting too hot and becoming degraded. Higher temperature, faster running engines with smaller chambers will make this even more difficult.

For these reasons, a three-shaft test facility was proposed to be built at the University of Nottingham, as part of the Gas Turbine and Transmissions Research Centre (G2TRC). This is designed to be a national facility that will allow the University and UK gas turbine manufacturers to test and evaluate new technologies for the development of engine and power gas-turbine oil systems and bearing chambers. It will also enable them to perform basic science to better understand how oil behaves in the harsh conditions found in a bearing chamber at flight conditions. This facility will better prepare the UK to perform in the global aerospace market and have translational benefits to related industries.
