Research activities

Dynamics research focusses on the aeroelasticity and structural dynamics phenomena in turbomachinery. Particular strengths are:

  • modelling of aero-engine  unsteady flows and associated phenomena such as rotating stall and surge 
  • prediction of blade and component vibration resulting from excitation in, or interaction with, unsteady aerodynamics: flutter, forced response, buffeting
  • the influence of nonlinear interfaces on the vibration of structural assemblies 
  • the integration of hybrid experimental and analytical technologies in modelling complex machinery structures

Much of the research is undertaken through the Rolls-Royce Vibration University Technology Centre, which has about 12 full-time research staff. Recent highlight successes include extensive application of the VUTC-developed forced response calculation methodology (the AU3D code) to the design of the Joint Strike Fighter LiftFan.
