EMTD are pleased to announce a partnership arrangement with TALENT based in Shanghai, China. TALENT will provide all of the installation, operation and training services for the EMTD suite of Blade Tip Timing technology in China.

We are also continuing our work with Shanghai Jiao Tong University to develop the use of BTT for a number of aerospace applications including Cross Wind testing and core compressor testing at the new Turbine test facility in Linggang.

EMTD made a number of presentations covering BTT technology awareness , in depth analysis techniques and the potential use of BTT in component certification testing to the Civil Aviation Administration of China (CAAC).

We hope to return to Shanghai in the near future to continue building internal measurement capability for Chinese companies.

 

EMTD attended the EVI-GTI meeting in Berlin at the end of September. Here we gave an update on the problems of developing Blade Health Monitoring (BHM) for aerospace applications. We are seeing great interest for this form of technology especially from the power generation industry.

EMTD launched a call for partners for a proposal under the Horizon 2020 programme and we now have had sufficient interest to begin the process of submission. We have tied up with a major power generation business in Europe in creating the proposal.

Our links with University of Manchester PhD programme is beginning to show signs of progress and we are now participating in a second round of measurement research. Further afield we are forging links in South Africa for the future development of the Blade Tip Timing technology.

One of our strengths is in providing a measurement consultancy service to help companies new to the advances in measurement choose the correct technology for the task and to manage their expectations. Unlike many turn-key suppliers EMTD intend to equip end users with the knowledge to apply and develop instrumentation with their own resource if required.

We have now begun shipping our networked BTT data acquisition system and MultiTool software to selected customers. Our next training course will take place in Shanghai week commencing 26th November 2016

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.

A short bio of the founder of EMTD has been added under the About EMTD Ltd page. Have a look at the page and find out more about Dr Peter Russhard.
