Posters
Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in the academic community. We look forward to seeing you there!
PO256: Spider - the fully automated ultrasonic system - a reliable solution for the detailed examination and condition assessment of individual critical areas of rotor blades onshore and offshore.
Pawel Lesniewski, Head of Non-Destructive Testing, Mistras Group
Abstract
Ultrasonic testing is the non-destructive testing method that enables to define the condition of the rotor blade in great detail. Visual inspections (drones or internal camera inspections) indicate visible damage, but often a hidden defects lead to the loss of wind blades. It is caused due to any production or service failure that only become noticeable when the blade component is exposed to particularly high loads.. With optimization of production costs, a lack of early detection can often have a catastrophic effect. This work describes non-destructive testing with the Spider system which transfers the possibility of serial inspection (known from laboratories or industrial facilities) to the field (onshore or offshore). It is proven and possible to detect hidden damages, cost effective in acceptable short time. The system allows only a team of two operators to effectively examine part of the rotor blade. The ability to apply it variety conditions: in test facilities after fatigue tests [1], uptower, onshore (blades without visible defects)[2] and offshore (visually damaged blades)[3], makes the system unique. It is an extension of the base version of the instrument, which was used for the detection of structural damage such as delamination, debondings and wrinkles. More attention has been paid to the safety of the application and the reduction of the human factor throughout the inspection process, when working under difficult conditions.
