A medium-scale test bench (see Figure 5) was developed to test a 10-15m long blade sections. These tests complement the results of the full-scale tests, since additional load combinations may be applied and the strength of each part of the blade is checked separately. Finally, the full-scale tests were redesigned to reproduce real field conditions as much as possible, applying full-scale aircraft design techniques based on various testing cycles at several different load levels and enlargement of the blade tests to consider all the hard-fatigue cycles expected in operation.

- The Gamesa high-efficiency lightning protection system (LPS) has been adapted to the size and modularity of G10X blades. The G10X LPS is already validated according to IEC61400-24 2010 requirements. - An optional light beacon system, made of non-conductive materials to prevent influences on the LPS, may be installed at the tip of the blade.
of the intermediate joint was validated according to aircraft regulations for fail-safe structures – the most demanding industrial standards worldwide-. The blade validation process included four levels: material tests, subcomponent tests, medium-scale tests and full-scale tests. All the critical design details (such as the intermediate joint system components) were tested at the subcomponent scale. At this validation level, several specimens were tested for each component and failure mode, ageing and temperature effects were tested and the effect of the critical process parameters was evaluated.
The complete validation programme included more than 250 coupon tests, 150 subcomponent tests, 25 mediumscale tests and a final series of fullscale tests according to IEC-61400-23 specifications. This programme required more than a hundred thousand skilled engineering man-hours. The field results of the first G10X4.5MW confirm the high performance of the wind turbine, including G10X modular blades. With the positive results of the highly demanding validation plan, the G10X-4.5MW is now ready for commercial exploitation with full confidence in the new technologies. n

Validation of G10X blades
A new blade validation concept was developed together with the new technologies. G10X blades comply with IEC regulations (the Type Certificate was obtained in 2011) and the design
