“We typically receive a 3D drawing from the customer, which we process in our CAD system, and there are a number of processing and assembly requirements
that we have to comply with. A finished wind turbine blade, for example, has no joints, so neither do our blade profiles. During the final processing stage, all blade profiles are polished by hand so that even the slightest groove is completely removed. The blade model contains a number of 0.4 mm pressure holes that are connected to a pressure scanner by means of thin urethane hoses.”
In its work with blade profiles, RIVAL focuses on surface smoothness, homogeneity and contour in order to create the best flow around the blade profile and achieve the best approximation of the theoretical dimensions. This produces the best possible data for analysis by the customer.
Well-documented blade profiles
The blade profiles are also very well documented, and measurements are taken to check all the customer’s dimensions. Everything is documented in a report, which is attached to the individual profile. The profile is packed in a custom-made transport box which protects it both during transport and subsequent storage at the customer’s premises.
