BladeSave Destructive Testing Trials

As the BladeSave project is drawing to a close, the consortium has completed the final stage of the project, by performing destructive testing trials with the BladeSave system.  

By proficiently merging the partners’ expertise in structural health monitoring, fibre optic sensors and management software, the BladeSave consortium has put together a system designed to reduce the risks associated with wind turbine blade failure.  

Project partner EWT has already performed a series of tests over a 3 month period, which yielded satisfying results concerning the system’s ability to detect blade cracks in early stages. But in order to further confirm the detecting capabilities of the BladeSave system, it has been submitted to one final test, executed by TWI. This involved undertaking destructive testing on a wind turbine blade, by simulating blade cracking and propagation using controlled loading. An additional ratification of the system was planned by running the BladeSave solution along with an existing commercial system and comparing the delivered results.  

As expected by the consortium, the tests demonstrated the capabilities of the system to detect early signs of damage caused by a series of factors, such as impacts or lightning strikes. The BladeSave solution monitors the amplification of these flaws and sends the information through the cloud for assessment. The solution developed within the BladeSave project supports maintenance decision-making for wind turbine operators, ensuring the inspection and repair processes occur precisely when needed, thus maximising component life span and reducing unscheduled repair, replacement and breakdown. 

A demonstration of the BladeSave system is programmed to take place on the 27th of August 2020, from 11.00 a.m to 12.00 a.m. CET, when project partners TWI and Renewable Advice are holding a free online webinar.
