Vibration Issues in the Aero-Engine Domain

Speaker: Rob Sutton (Atkins)

Rob Sutton is a Principal Engineer with Atkins Limited and Member of the Institution of Mechanical Engineers. He has extensive experience of structural analysis of airframe and gas turbine components. He has spent a number of years working for and with Rolls-Royce plc gaining experience in various aspects of aero engine vibration assessment from preliminary design requirements through to detailed analysis, testing and support to in-service engines.


Vibration is an inherent problem in rotating machinery and one of the main concerns when designing aero engine components. The effects of vibration can be an ongoing issue during aircraft service and are a common feature of failure investigations. The presentation will provide a practical guide to the tools and methods commonly adopted in the assessment of aero engine vibration. The presentation will focus on the analysis of blades and vanes covering the following areas.

  • Sources of blade vibration.
  • Prediction of blade/assembly frequencies and resonances using finite element analysis.
  • Rig testing of blades/vanes and assemblies.
  • Blade strength assessments.
  • Engine testing and vibration measurement techniques.
  • Vibration management and mitigation methods.

Recordings of past events

Most of our evening meetings are recorded, including the biennial Mallet-Milne Lecture. The recordings are managed by the ICE and are made available for a year after the event. Go to ICE's Event Archive to find recordings of recent SECED events. SECED members (and ICE members) get exclusive early access to recorded lectures for a period of three months after the event. After this period, recordings are made available to all users.


The events archive is not actively maintained. This means that the information provided for each past event may no longer be correct. For example, people may no longer work for the companies to which they were previously affiliated, and hyperlinks may be broken. SECED assumes no responsiblity for the accuracy of any information contained in the events archive.
