Zusammenfassung:	The method CND (200) of non-destructive testing of a wind turbine blade (10), comprises a step (201) of stressing the structure of the blade through a modification of a physical characteristic of a fluid filling the hollow interior volume (18) of the blade, a step (202) of observing zones to be tested of the exterior surface (19) of the blade, with the contactless measurement of a physical parameter on points of the exterior surface (19) of the blade and a step (203) of comparing the map of the values of the physical parameter measured with a reference map. A system CND for checking the structural integrity of a wind turbine blade (10) according to the method CND comprises an aerothermic device (40) for modifying the physical conditions, temperature or pressure, of a fluid filling the hollow interior volume (18) of the blade, a device for contactless measurement (50) of a physical parameter, temperature or dimensions, of the exterior surface (19) of the blade, and a device for processing the measurements.
