Measurement of safety critical components NPL's extensive turbine blade measurement expertise helps customer improve safety and drive down costs. A customer from the aerospace sector approached NPL Huddersfield to measure their high value machined turbine blades. NPL measured in-use wear of the components, helping the customer to trouble shoot any potential safety issues. The challenge Turbine blades used in aerospace engines are very complex, freeform, high value components that are very challenging to measure to first principles. Yet the measurement tolerances for them are very tight due to the obvious safety issues that can arise if a part is out of tolerance (i.e. in-use engine failure). The solution NPL staff with between them over nine decades of experience of measuring turbine blade
