Objective
The intended research project "3-D Motion Analysis in Full-scale Wind Turbines" addresses crucial technical aspects in the assessment and testing of next designs and development in the next generation of wind turbines. These are characterized by increasing size and increasingly flexible structures.
The dynamics of rotor blades, as well as their interaction with the hub, tower and generator structures must be well understood in the design phase, and must be fully validated by experiment on the full-scale product. Structural fatigue and the risk of dramatic failure must be at an absolute minimum to warrant social and environmental acceptance without which there is no economic future.
Current experimentation on rotor blade motion is limited to specially instrumented prototypes, the sensors being of the strain gauge and accelerometer type which are attached onto the structures under test either at the surface or into specially machined cavities. Both by this fact plus by the necessary wiring and elaborate electric collector structures at the hub these methods exert a generally unaccountable influence on the test object behaviour.
The present proposal removes the physical sensors and wiring from the rotor blades, and instead uses a set of passive optical markers, which are no more than sub-millimeter thin stickers of commercial retro-reflective sheet glued at landmark points to the rotor blade, hub and tower surfaces. The markers are imaged by a high-resolution multiple camera and computer system, which yields the marker coordinates in real time at 100 images/s, so that this non-contacting method plus associated software can deliver a full 3-D movement analysis in a minimum of time.
By implication, this remote camera/computer method can be applied to otherwise unprepared structural prototypes as well as to standard production samples, which shall benefit the penetration of an encompassing test and verification programme in wind turbine design and validation. The method is targeted at the national or European-level R&D and testing facilitiesi n the renewable (wind) energy sector, to the benefit and support of this sector's innovative manufacturers.
This new, rapid turnover facility should then contribute to a better and dependable, economic and safe product.
