Gas Turbine and Transmissions Research Centre


The Gas Turbine and Transmissions Research Centre (G2TRC) is a 45-strong multi-disciplinary research group focussed on developing new technologies, analysis methods and understanding for existing and future gas turbine core and transmissions architectures.

The engineering of high-performance gas turbine transmission systems requires competences and expertise in:  

  • fluid-flow and heat transfer to understand and model complex two-phase flows of oil
  • material strength properties and characteristics, contact analysis, wear and fatigue at standard and elevated temperatures
  • static and dynamic modelling of seals, shafts and bearings and the mechanical behaviour of support structures  

G2TRC is home to the Rolls-Royce University Technology Centre (UTC) in Gas Turbine Transmission Systems, established in 1997 to work closely with senior engineers in Rolls-Royce on projects that impact directly on the development of new engines.

Key aims and expertise

  • mathematical and CFD modelling of gas-liquid flows for simulation of engine core and transmission systems with heat transfer
  • the previous with meshing gears and associated tribology
  • rotor-dynamics and gearbox dynamics; coupled electromechanical systems
  • CFD modelling for blades, seal, cavity and cooling flow applications
  • sealing engineering and technologies
  • thermomechanical properties of high-performance alloys
  • modelling and controlling solidification processes
  • structural integrity assessment of aero-engine (transmission) components including shafts, splines and casing structures through experimental testing and modelling
  • modelling of component manufacture including welding and joining
  • design guidelines for bearing chambers, gearboxes and oil systems
  • contribution to WEM and CAE-based design
  • engine-airframe near-direct solution approaches
  • optimisation
  • 2-phase flow Smooth Particle Hydrodynamics (SPH)
