Validated for measurement results thanks to HBK
Within the context of testing and validation, the CoLT testing team relies on measurement technology from HBK. To ensure the best possible measurement results, only HBK strain gauges were used in the test rig. In total, over 550 flexible and easy to deploy HBK strain gauges were used in the Airbus A350-900 Winglet Wingtip Full Scale Certification Program - including 307 strain gauge rosettes 1 RY91-6 / 120 for the analysis of biaxial stress state with unknown principal stress directions and 257 linear strain gauges 1-LY41-6 / 120 to measure strain in one direction. Their task: validating the FEM calculation results required for type certification of the new Airbus model. During these tests, the HBK components confirmed the test engineers' positive experiences from the past. Even under challenging test conditions, they provided the expected precise measured values which confirmed the calculated interdependencies of component behavior. This completes another major step towards type certification.
