1 1 | Program Name or Ancillary Water Power Peer Review Remote Monitoring of the Structural Health of Hydrokinetic Composite Turbine Blades Joshua L. Rovey, Ph.D. Missouri University of Science & Technology 573-341-4613 Sept. 27, 2011 Remote Monitoring of the Structural Health of Hydrokinetic Composite Turbine Blades Joshua L. Rovey, PI K. Chandrashekhara, Co-PI Mechanical & Aerospace Engineering Missouri University of Science & Technology

2 2 | Wind and Water Power Purpose, Objectives, & Integration Purpose: Reduce operation and maintenance (O&M) costs of hydrokinetic energy systems by remotely monitoring the health of turbine blades Specific Objective: Proof-of-concept demonstration of a composite turbine blade that can acquire and transmit data about its structural health Larger DoE Program Mission: Focused on accelerating development and deployment of MHK systems for clean, affordable energy Project Relevance to Mission: Typical O&M costs are 70- 95% of total investment cost, reducing O&M costs with remote monitoring may make these systems viable on a large scale with widespread use

3 3 | Wind and Water Power Component Concept Fiber optic strain gage embedded in composite turbine blade of hydrokinetic energy system Internal blade electronics module acquires strain data Data broadcast acoustically underwater to stationary relay module Data broadcast wirelessly through air to remote monitoring personnel

4 4 | Wind and Water Power Technical Approach Proof of Concept Demonstration of Concept Parallel development of 1) embedded sensor technology and 2) underwater communication capability Integration of parallel efforts to demonstration proof of concept

5 5 | Wind and Water Power Fabricated composite material with embedded “dummy” fibers Completed initial strain measurements on composite material – electrical strain gage Demonstrated PC-in-the-loop underwater acoustic communication Progress to Date Coated fiber Uncoated fiber Strain response for free deflection Composite material with embedded fibers Signals sent and received thru water

6 6 | Wind and Water Power Important Issues Is there Industry Interest in Our Technology? YES! PI attended GMREC in May 2011, met industry leaders in hydrokinetic energy Follow-up discussions with Free Flow Power and THOR Energy revealed YES there is interest, that interest is two-fold: 1.Monitoring of commercially deployed final systems, reducing O&M costs 2.Monitoring of in-water testing of prototype systems to detect real-time transient effects/impacts on blades Key Technological Issue Signal processing of embedded fiber optic strain gage data Strain frequency spectrum must be analyzed before being communicated and broadcast Our data shows what range of frequencies important to analyze, but how to analyze these data in-situ? Key Technological Solution Incorporate new data analysis algorithms and electronics We are collaborating with a colleague in electrical eng. who has experience developing signal analyzers for fiber optic strain gages

9 9 | Wind and Water Power Additional Slides The following slides are for information purposes only

10 10 | Wind and Water Power Guidelines for number of slides (Not a template slide – for information purposes only) Because of time constraints, lower TRL level projects (shorter term and smaller award amounts) will be introduced and briefly presented by DOE staff, though project PIs will be responsible for providing project background material and slides. Presentations for these projects will be allotted only 5 minutes per project, therefore please provide no more than 5-6 slides. Slides may include pictures, graphics, or information that is additional to what is requested in the template (above), however, slides must include all information that is indicated in the template. Project PIs will also be available for Q&A with the Peer Reviewers (via teleconference) during the timeslot allotted for the lower TRL level projects.

11 11 | Wind and Water Power Preparation Instructions (Not a template slide – for information purposes only) Do not include any proprietary, copyrighted, or confidential information. Do not mark any slide with “Official Use Only” or any similar restriction used by your organization. Please name your electronic MS PowerPoint presentation file as follows (use the first 4 letters of your title): [Title_Organization_LastName.ppt]. Do not incorporate animations or special effects since all presentations will be saved as PDF files for presentation and for posting on the web. Animations critical to describing the project may be presented as separate files, however they must be approved by the Program and presented within your allotted time.

12 12 | Wind and Water Power Final Instructions (Not a template slide – for information purposes only) Your presentation, in MS PowerPoint format, is due to Ed Eugeni at by September 27 th. If your presentation is too large to email, contact Ed Eugeni at 240-223-5552 for alternative delivery options. Reviewers will be receiving your presentation prior to the meeting. In order to supply adequate time for the reviewers to review your material prior to the meeting, you MUST submit your presentation by close of business on September 27th. Your project is subject to a score reduction penalty if you fail to meet this deadline.
