Aims

Placeholder2
 
The TRENT series of Rolls-Royce civil aeroengines employs a three-shaft system to transmit power from the three turbines to the fan and two compressors.  There are three bearing chambers, each with a support structure connecting it to the engine casing.  There is also a system of gearboxes incorporating gears that operate with high peripheral speeds that connects the mainline shafts to the auxiliaries on the outside of the engine.  These are all critical components involved in meeting the industry’s need for major reductions in damaging emissions, noise and drag.  This will require shafts to have smaller diameters, transmit higher torque and run at higher speeds and higher temperatures.  The TRENT series of Rolls-Royce civil aeroengines employs a three-shaft system to transmit power from the three turbines to the fan and two compressors.  There are three bearing chambers, each with a support structure connecting it to the engine casing.  There is also a system of gearboxes incorporating gears that operate with high peripheral speeds that connects the mainline shafts to the auxiliaries on the outside of the engine.  These are all critical components involved in meeting the industry’s need for major reductions in damaging emissions, noise and drag.  This will require shafts to have smaller diameters, transmit higher torque and run at higher speeds and higher temperatures.  

The Group’s aim is to provide the technology to enable these improvements to take place.

We are doing internationally-leading work on new advanced materials, novel designs for shafts, couplings, support structures and casings, the use of high duty bearings, the dynamic behaviour of high performance gearboxes for driving auxiliaries, the performance of the oil system that lubricates and cools the bearings and gears and the design of seals to prevent oil leaking from the transmission system.
