EMTD chaired the Blade Tip Timing papers session at the AIVELA conference in Ancona Italy.

Four papers were presented covering sensors and BTT technology uncertainty and its link with model validation using SLDV.

We attended the 7^th EVI-GTI Gas Turbine Instrumentation conference at the Millennium Hotel in London.

There were a number of interesting articles covering many aspects of measurement in the Gas Turbine Industry. EMTD led the Blade Tip Timing standards committee meeting although this was limited to conference attendees where the aims of the ISA107.1 group were re-visited and a request for volunteers to head some of the work packages was made.

To support some of the work being undertaken in the ISA 107.1 EMTD have launched a call for potential partners for a Horizon 2020 project.

Horizon 2020 is the biggest EU Research and Innovation programme ever with nearly €80 billion of funding available over 7 years (2014 to 2020) – in addition to the private investment that this money will attract. It promises more breakthroughs, discoveries and world-firsts by taking great ideas from the lab to the market.

We are working with Loughborough University of Aeronautical and Automotive Engineering to define the project and work packages. We have gained support from a number of large companies who have shown an interest in our outline proposal.

What and who we are seeking?

• Potential collaborators/industrial partners.
• Involvement with H2020 Calls.
• Organisations interested in instrumentation, health monitoring, advanced sensors and method validation.
• Software companies in FEM, CFD arena, sensor developers, mechanical test houses.
• End Users.

What are the market opportunity are we addressing?

• Encouraging market opportunity.
• Reduce costs of health monitoring systems projects.
• Validating new technology and methods for the supply chain.
• Creating new standards for applying measurement technology providing consistent & repeatable product certification data.
• Defining & validating the relationship between FEM, CFD and measurement.

We are excited to announce that we have a new product available. The Blade Tip Timing (BTT) hardware simulator is our first hardware product.

For more information see the new Products Page.

Validation of axial position algorithms can be performed using our modified spinning rig. A spring loaded fan allows axial shift with increasing fan load.  The axial movement is acquired accurately from the rotor using optical techniques and this can then be compared to that calculated from the tip timing probes.

This allows us to improve the accuracy and resolution of our methods

The BTT spinning rig has been adapted to allow the investigation of axial movement measurement and to produce data sets that will allow surge deflection algorithms to be validated.

A reference disk and a new high speed motor enable us to precisely measure the axial movement of a spring loaded rotor that is used to create axial position shifts with increasing load.  The motor rating has been increased to 500W and the maximum speed is now 3000 rpm.

A new video has been added. Validation of axial position algorithms can be performed using our modified spinning rig with a spring loaded fan that allows
axial shift with increasing fan load.  The axial movement is acquired accurately from the rotor using optical techniques and this can then be compared to that calculated form the tip timing probes.

It is a few weeks since we attended this conference and presented at a panel session discussing Gas Turbine Instrumentation and at the technical session  presenting our latest work on blade health monitoring systems.

The work of AVT 229 has now concluded and we are working closely with our colleagues to propose a new activity to include predicted and measured remaining life and maturation of Engine Health Monitoring (EHM) systems for gas turbine applications.

We hope to attend the EVI-GTI conference in London later this year where we will be presenting some of our finding from the BTT research we are undertaking.

The small scale rig work has started and you can watch the first of many YouTube videos of it in operation. Watch to the end to see the first blanking plate we are testing in order to excite the blades. Much more work is planned and updates will be posted on here and on the rig page.

We will be presenting a paper covering the topic of Blade Health Monitoring at this symposium in Poland 20/4/2015 – 23/04/2015.

We will be happy to discuss any BTT relatred questions you may have whilst at the conference.

 

We have just delivered a training course over a period of three days to a group of customers based in Europe.  This course covered the theory of how BTT processing works followed by analysis examples and the use of currently available BTT analysis software tools.  Demonstrations of hardware were also provided with a look at a simple BTT rig that is currently under construction allowing the creation of controlled data sets.
