WMC helps rotor blades fly


Where WMC usually is active in in the field on non-flying wind turbine rotor blades , we have recently been involved in certification testing of rotor blades for a flying car, the PAL-V ONE.

As part of the product development and certification procedure, a number of structural tests were performed on a rotor blade for PAL-V's hybrid car and gyroplane. Quasi static tests were successfully performed in WMC's large test frame, which can accommodate specimens of up to ca. 5 m and loads of up to 350 tonnes.

WMC at the 20th ICCM in Copenhagen

A team of WMC material researchers attended the 20th International Conference on Composite Materials (ICCM20) in Copenhagen, from 19 to 24 July 2015.

The WMC material research team, represented by Francisco Lahuerta, Iuri Barcelos and Sibrand Raijmaekers, contributed with three oral presentations based on submitted scientific papers. The works by Iuri and Sibrand focused on the natural and accelerated ageing of composite materials, while the one by Francisco dealt with characterization of thick laminates.

WMC contribution to certification of ENO rotor blade EB 56

Knowledge Centre WMC contributed with an extensive program consisting of static and fatigue testing to the successful completion of the overall certification of the Rostock-based manufacturer ENO rotor blade EB 56 per the GL and IEC guidelines by renowned certification body DNV GL. Testing at WMC was carried out according to the IEC-61400-23 test protocol.
For details on this rotor blade and its specific applications, see www.eno-energy-com.

Contact group Fractography Meeting

November 4, 2015 WMC will host a meeting of the Dutch "Contactgroep Fractografie (Contact group Fractography)". At the two annual meetings, material failures and failure causes are discussed. The meetings are open for everyone, but registration is required because the number of attendencies is limited.

The following topics will be discussed: 'Long-term protection of steel offshore structures: is that possible?; 'Material Failure after Hydrothermal Ageing of Glass/Epoxy Composites for Wind Turbine Blades'; 'Testing Methods for Thick Laminates and Fracture models Calibrations' and 'Oil filter analyses prevent damage'. For more details, including how to attend the meeting, see the programme leaflet (in Dutch).

Full-scale blade testing

WMC has developed the procedures for blade tests since 1984 and has tested many blades for many of the largest blade manufacturers ever since.
